138-0249 GENERAL
NOTICE TO CONTRACTOR – ASBESTOS CONTAMINATED SOIL AND ENVIRONMENTAL INVESTIGATIONS Environmental site investigations have been conducted that involved the sampling and laboratory analysis of soil, sediment, surface water and groundwater, collected from various locations within the Project Limits. The results of these investigations indicated the presence of asbestos contaminated soil and sediment (ACS) within the Project Limits. In addition, detectable concentrations of volatile organic compounds (VOCs), extractable total petroleum hydrocarbons (ETPH), polynuclear aromatic hydrocarbons (PAHs), and RCRA metals (total and leachable arsenic and lead and leachable chromium) in the soil within proposed construction areas, at concentrations that exceed the Connecticut Remedial Standard Regulations (CT RSR) criteria applicable to Residential Direct Exposure Criteria and/or Industrial/Commercial Direct Exposure Criteria and the GB Pollutant Mobility Criteria. Based on the investigation results, several ACS Areas of Environmental Concern (ACS AOECs) have been identified within the Project Limits. The remaining portion of the Project Limits not identified as an ACS AOEC shall be considered by the Contractor to be an AOEC. The CTDEEP groundwater classification beneath the Project is “GB” and the surface water classification of the Housatonic River within the Project Limits is “SB”. Limited groundwater and surface water data collected in and in the vicinity of the Project Limits indicate the potential for constituents of concern to be present at elevated concentrations in groundwater or wastewater generated during construction dewatering/solidification and decontamination activities. Water from these activities will require special management in accordance with Item No. 0204213A - Handling Contaminated Groundwater. The Contractor is hereby notified of the following and shall refer to the Project Specifications for additional details:
• For the purposes of health and safety, and as specified in more detail in Item No. 0101021A – Environmental Health and Safety – Asbestos Contaminated Soil, the Contractor shall consider that asbestos fibers are present in all soils, sediment, and dewatering and decontamination fluids and prepare the HASP and plan all work activities accordingly. WORKER HEALTH AND SAFETY PROTOCOLS WHICH ADDRESS POTENTIAL AND/OR ACTUAL RISK OF EXPOSURE TO SITE SPECIFIC HAZARDS ARE SOLELY THE RESPONSIBILITY OF THE CONTRACTOR.
• Given the presence of ACS, the Contractor will be responsible for designing and implementing (using properly trained, experienced and credentialed personnel) a rigorous Air Monitoring Plan to address the risk of exposure to both on-site workers and that of individuals beyond the work site throughout the duration of the Project.
10/04/17
138-0249 GENERAL
• Given the presence of ACS, the Contractor will be responsible for defining Regulated Areas within the Project Limits as necessary. A “Regulated Area” is where airborne concentrations of asbestos exceed (or there is a reasonable possibility they may exceed) a permissible exposure limit (PEL). Said area(s) shall be demarcated such that the number of people allowed in the area is strictly controlled (authorized personnel only) and the people outside the area are protected from exposure. The Contractor shall refer to 29 Code of Federal Regulations (CFR) 1926.1101 for additional details. Note that equipment or materials exposed to ACS or any ACS-impacted items shall not be left outside of a Regulated Area.
• There is an existing Project WSA in Stratford that is to be relocated by the Contractor. Prior to relocation, materials present in the bins from previous Project activities must be disposed of by the Contractor. In addition, ACS AOEC 3 must be excavated prior to the reconstruction of one of the WSA bins in Stratford as indicated on the Project Plans. The proposed temporary WSAs shown on the plans are to be used exclusively for temporary stockpiling of excavated ACS and/or Controlled Materials from within the Project AOECs for determination of disposal classification.
• Two specifications have been prepared for handling materials derived from the Project; one relates to the handling of ACS whereas the other relates to the handling of Controlled Materials. The Contractor shall be aware that the provisions of Item No. 0020805A - Handling Asbestos Contaminated Soil specification differ from those outlined in Item No. 0101117A – Controlled Material Handling.
• The Contractor shall be responsible for the decontamination of all items that have been exposed to ACS prior to materials or equipment leaving a Regulated Area (or before a Regulated Area is closed out) and/or passing over any public roadway at any time.
• Soil investigations conducted for an adjacent proposed CTDOT Project have indicated the presence of Raymark Waste in defined areas within Project Limits for 0138-0249 as shown on Project Plan ENV-3. The Contractor shall be aware that no intrusive work may be conducted within these defined areas of Raymark Waste without the prior notification to the Department and approval from the United States Environmental Protection Agency (US EPA).
The Sections which shall be reviewed by the Contractor include, but are not limited to, the following:
• Item No. 0020805A – Handling Asbestos Contaminated Soil
• Item No. 0020806A – Disposal of Asbestos Contaminated Soil • Item No. 0020807A – Dewatering and Solidification of Asbestos Contaminated Soil and
Sediment

3 Typha spp. are native species which provide good water quality renovation and other
functions/values. However, they are aggressive colonizers which, given the opportunity,
will preclude establishment of other native species. They are included in this list as species
not to be planted, not because they are undesirable in an established wetland, but to provide
opportunities for other species to become established. It is likely they will eventually move
in without human assistance.

GENERAL
Placement: The mixture shall be placed and compacted to provide a smooth, dense surface with
a uniform texture and no segregation at the specified thickness and dimensions indicated in the
plans and specifications.
When unforeseen weather conditions prevent further placement of the mixture, the Engineer is
not obligated to accept or place the bituminous concrete mixture that is in transit from the Plant.
In advance of paving, traffic control requirements shall be set up, maintained throughout
placement, and shall not be removed until all associated work including density testing is
completed.
The Contractor shall inspect the newly placed pavement for defects in the mixture or placement
before rolling is started. Any deviation from standard crown or section shall be immediately
remedied by placing additional mixture or removing surplus mixture. Such defects shall be
corrected to the satisfaction of the Engineer.
Where it is impractical due to physical limitations to operate the paving equipment, the Engineer
may permit the use of other methods or equipment. Where hand spreading is permitted, the
mixture shall be placed by means of suitable shovels and other tools, and in a uniformly loose
layer at a thickness that will result in a completed pavement meeting the designed grade and
elevation.
Placement Tolerances: Each lift of bituminous concrete placed at a specified thickness shall
meet the following requirements for thickness and area. Any pavement exceeding these limits
shall be subject to an adjustment or removal. Lift tolerances will not relieve the Contractor from
meeting the final designed grade. Lifts of specified non-uniform thickness, i.e. wedge or shim
course, shall not be subject to thickness and area adjustments.
a) Thickness- Where the average thickness of the lift exceeds that shown on the plans
beyond the tolerances shown in Table 4.06-3, the Engineer will calculate the thickness
adjustment in accordance with Article 4.06.04.
TABLE 4.06-3: Thickness Tolerances
Mixture Designation Lift Tolerance
S1 +/- ⅜ inch
S0.25, S0.375, S0.5 +/- ¼ inch
Where the thickness of the lift of mixture is less than that shown on the plans beyond the
tolerances shown in Table 4.06-3, the Contractor, with the approval of the Engineer, shall
take corrective action in accordance with this specification.
b) Area- Where the width of the lift exceeds that shown on the plans by more than the
specified thickness, the Engineer will calculate the area adjustment in accordance with
Article 4.06.04.
Rev. Date 9/30/2016
English
GENERAL
c) Delivered Weight of Mixture - When the delivery ticket shows that the vehicle exceeds the
allowable gross weight for the vehicle type, the Engineer will calculate the weight
adjustment in accordance with Article 4.06.04.
Transverse Joints: All transverse joints shall be formed by saw-cutting to expose the full
thickness of the lift. Tack coat shall be applied to the sawn face immediately prior to additional
mixture being placed.
Compaction: The Contractor shall compact the mixture to meet the density requirements as
stated in Article 4.06.03 and eliminate all roller marks without displacement, shoving, cracking,
or aggregate breakage.
When placing a lift with a specified thickness less than one and one-half (1 ½) inches, or a
wedge course, the Contractor shall provide a minimum rolling pattern as determined by the
development of a compaction curve. The procedure to be used shall be documented in the
Contractor’s QCP for placement and demonstrated on the first day of placement.
The use of the vibratory system on concrete structures is prohibited. When approved by the
Engineer, the Contractor may operate a roller using an oscillatory system at the lowest frequency
setting.
If the Engineer determines that the use of compaction equipment in the dynamic mode may
damage highway components, utilities, or adjacent property, the Contractor shall provide
alternate compaction equipment. The Engineer may allow the Contractor to operate rollers in the
dynamic mode using the oscillatory system at the lowest frequency setting.
Rollers operating in the dynamic mode shall be shut off when changing directions.
These allowances will not relieve the Contractor from meeting pavement compaction
requirements.
Surface Requirements:
Each lift of the surface course shall not vary more than ¼ inch from a Contractor-supplied 10
foot straightedge. For all other lifts, the tolerance shall be ⅜ inch. Such tolerance will apply to
all paved areas.
Any surface that exhibits these characteristics or exceeds these tolerances shall be corrected by
the Contractor at its own expense.
7. Longitudinal Joint Construction Methods: The Contractor shall use Method I- Notched
Wedge Joint (see Figure 4.06-1) when constructing longitudinal joints where lift thicknesses are
between 1½ and 3 inches. S1.0 mixtures shall be excluded from using Method I. Method II Butt
Joint (see Figure 4.06-2) shall be used for lifts less than 1½ inches or greater than or equal to 3
inches. During placement of multiple lifts, the longitudinal joint shall be constructed in such a
Rev. Date 9/30/2016
English
GENERAL
manner that it is located at least 6 inches from the joint in the lift immediately below. The joint
in the final lift shall be at the centerline or at lane lines. Each longitudinal joint shall maintain a
consistent offset from the centerline of the roadway along its entire length. The difference in
elevation between the two faces of any completed longitudinal joint shall not exceed ¼ inch in
any location.
Method I - Notched Wedge Joint:
FIGURE 4.06-1: Notched Wedge Joint
A notched wedge joint shall be constructed as shown in Figure 4.06-1 using a device that is
attached to the paver screed and is capable of independently adjusting the top and bottom vertical
notches. The device shall have an integrated vibratory system.
The taper portion of the wedge joint must be placed over the longitudinal joint in the lift
immediately below. The top vertical notch must be located at the centerline or lane line in the
final lift. The requirement for paving full width “curb to curb” as described in Method II may be
waived if addressed in the QC plan and approved by the Engineer.
The taper portion of the wedge joint shall be evenly compacted using equipment other than the
paver or notch wedge joint device.
The taper portion of the wedge joint shall not be exposed to traffic for more than 5 calendar days.
Any exposed wedge joint must be located to allow for the free draining of water from the road
surface.
The Engineer reserves the right to define the paving limits when using a wedge joint that will be
exposed to traffic.

If Method I, Notched Wedge Joint cannot be used on lifts between 1.5 and 3 inches, Method III
Butt Joint may be substituted according to the requirements below for “Method III – Butt Joint
with Hot Pour Rubberized Asphalt Treatment.”
Method II - Butt Joint:
FIGURE 4.06-2: Butt Joint
When adjoining passes are placed, the Contractor shall utilize equipment that creates a near
vertical edge (refer to Figure 4.06-2). The completing pass (hot side) shall have sufficient
mixture so that the compacted thickness is not less than the previous pass (cold side). The end
gate on the paver should be set so there is an overlap onto the cold side of the joint.
The Contractor shall not allow any butt joint to be incomplete at the end of a work shift unless
otherwise allowed by the Engineer. When using this method, the Contractor is not allowed to
leave a vertical edge exposed at the end of a work shift and must complete paving of the roadway
full width “curb to curb.”
Method III- Butt Joint with Hot Poured Rubberized Asphalt Treatment: If Method I
Wedge Joint cannot be used due to physical constraints in certain limited locations; the
contractor may submit a request in writing for approval by the Engineer, to utilize Method III
Butt Joint as a substitution in those locations. There shall be no additional measurement or
payment made when the Method III Butt Joint is substituted for the Method I Notched Wedge
Joint. When required by the contract or approved by the Engineer, Method III (see Figure 4.06-

All of the requirements of Method II must be met with Method III. In addition, the longitudinal
vertical edge must be treated with a rubberized joint seal material meeting the requirements of
ASTM D 6690, Type 2. The joint sealant shall be placed on the face of the “cold side” of the
butt joint as shown above prior to placing the “hot side” of the butt joint. The joint seal material
shall be applied in accordance with the manufacturer’s recommendation so as to provide a
uniform coverage and avoid excess bleeding onto the newly placed pavement.
8. Contractor Quality Control (QC) Requirements: The Contractor shall be responsible for
maintaining adequate quality control procedures throughout the production and placement
operations. Therefore, the Contractor must ensure that the materials, mixture and work provided
by Subcontractors, Suppliers and Producers also meet contract specification requirements.
This effort must be documented in Quality Control Plans and address the actions, inspection, or
sampling and testing necessary to keep the production and placement operations in control, to
determine when an operation has gone out of control and to respond to correct the situation in a
timely fashion.
The Standard QCP for production shall consist of the quality control program specific to the
production facility.
There are three components to the QCP for placement: a Standard QCP, a Project Summary
Sheet that details project specific information, and if applicable a separate Extended Season
Paving Plan as required in Section 9 “Temperature and Seasonal Requirements”.
The Standard QCP for both production and placement shall be submitted to the Department for
approval each calendar year and.at a minimum of 30 days prior to production or placement.
Production or placement shall not occur until all QCP components have been approved by the
Engineer.
Each QCP shall include the name and qualifications of a Quality Control Manager (QCM). The
QCM shall be responsible for the administration of the QCP, and any modifications that may
become necessary. The QCM shall have the ability to direct all Contractor personnel on the
project during paving operations. All Contractor sampling, inspection and test reports shall be
reviewed and signed by the QCM prior to submittal to the Engineer. The QCPs shall also
include the name and qualifications of any outside testing laboratory performing any QC
functions on behalf of the Contractor.
Approval of the QCP does not relieve the Contractor of its responsibility to comply with the
project specifications. The Contractor may modify the QCPs as work progresses and must
document the changes in writing prior to resuming operations. These changes include but are not
limited to changes in quality control procedures or personnel. The Department reserves the right
to deny significant changes to the QCPs.

GENERAL
QCP for Production: Refer to Section M.04.03-1.
QCP for Placement: The Standard QCP, Project Summary Sheet, and Extended Season Paving
Plan shall conform to the format provided by the Engineer. The format is available at http://www.ct.gov/dot/lib/dot/documents/dconstruction/pat/qcp_outline_hma_plac
ement.pdf.
The Contractor shall perform all quality control sampling and testing, provide inspection, and
exercise management control to ensure that placement conforms to the requirements as outlined
in its QCP during all phases of the work. The Contractor shall document these activities for each
day of placement.
The Contractor shall submit complete field density testing and inspection records to the Engineer
within 48 hours in a manner acceptable to the Engineer.
The Contractor may obtain one (1) mat core and one (1) joint core per day for process control,
provided this process is detailed in the QCP. The results of these process control cores shall not
be used to dispute the Department determinations from the acceptance cores. The Contractor
shall submit the location of each process control core to the Engineer for approval prior to taking
the core. The core holes shall be filled to the same requirements described in sub-article 4.06.03-
10.
9. Temperature and Seasonal Requirements: Paving, including placement of temporary
pavements, shall be divided into two seasons, “In-Season” and “Extended-Season”. In-Season
paving occurs from May 1 – October 14, and Extended Season paving occurs from October 15-
April 30. The following requirements shall apply unless otherwise authorized or directed by the
Engineer:
• Mixtures shall not be placed when the air or sub base temperature is less than 40°F
regardless of the season.
• Should paving operations be scheduled during the Extended Season, the Contractor must
submit an Extended Season Paving Plan for the project that addresses minimum delivered
mix temperature considering WMA, PMA or other additives, maximum paver speed,
enhanced rolling patterns and the method to balance mixture delivery and placement
operations. Paving during Extended Season shall not commence until the Engineer has
approved the plan.
10. Obtaining Bituminous Concrete Cores: This Section describes the methodology and
sampling frequency the Contractor shall use to obtain pavement cores.
Coring shall be performed on each lift specified to a thickness of one and one-half (1 ½) inches
or more within 5 days of placement. The Contractor shall extract cores (4 or 6 inch diameter for
S0.25, S0.375 and S0.5 mixtures 6 inch diameter for S1.0 mixtures) from locations determined

GENERAL
by the Engineer. The Engineer must witness the extraction, labeling of cores and filling of the
core holes.
A density lot will be complete when the full designed paving width and length of the lot has been
placed and shall include all longitudinal joints between the curb lines. HMA S1 mixes are
excluded from the longitudinal joint density requirements.
A standard density lot is the quantity of material placed within the defined area exclusive of any
structures. A combo density lot is the quantity of material placed within the defined area
inclusive of structures less than or equal to 500 feet long. A bridge density lot is the quantity of
material placed on a structure larger than 500 feet in length.
Prior to paving, the type and number of lot (s) shall be determined by the Engineer. The number
of cores per lot shall be determined in accordance to Tables 4.06-4, 4.06-5A and 4.06-5B.
Noncontiguous areas such as highway ramps may be combined to create one lot. Combined
areas should be set up to target a 2000 ton lot size. The longitudinal locations of mat cores
within a lot containing multiple paving passes will be determined using the total distance covered
by the paver. The locations of the joint cores will be determined using the total length of
longitudinal joints within the lot.
Sampling is in accordance with the following tables:

Note: (1) If a combo lot mat or joint core location randomly falls on a structure, the core is to be obtained on the structure in
addition to the core(s) required on the structure.
After the lift has been compacted and cooled, the Contractor shall cut cores to a depth equal to or
greater than the lift thickness and remove them without damaging the lift(s) to be tested. Any
core that is damaged or obviously defective while being obtained will be replaced with a new
core from a location within 2 feet measured in a longitudinal direction.
A mat core shall not be located any closer than one foot from the edge of a paver pass. If a
random number locates a core less than one foot from any edge, the location will be adjusted by
the Engineer so that the outer edge of the core is one foot from the edge of the paver pass.
Method I, Notched Wedge Joint cores shall be taken so that the center of the core is 5 inches
from the visible joint on the hot mat side (Figure 4.06-5).
FIGURE 4.06-5: Notched Wedge Joint Cores
When Method II or Method III Butt Joint is utilized, cores shall be taken from the hot side so the

approved by the Engineer. The container shall have a lid capable of being locked shut and
tamper proof. The Contractor shall use foam, bubble wrap, or another suitable material to
prevent the cores from being damaged during handling and transportation. Once the cores and
MAT-109 are in the container the Engineer will secure the lid using a security seal. The security
seal’s identification number must be documented on the MAT-109. Central Lab personnel will
break the security seal and take possession of the cores.
FIGURE 4.06-4: Labeling of Cores
Each core hole shall be filled within four hours upon core extraction. Prior to being filled, the
hole shall be prepared by removing any free water and applying tack coat using a brush or other
means to uniformly cover the cut surface. The core hole shall be filled using a bituminous
concrete mixture at a minimum temperature of 240ºF containing the same or smaller nominal
maximum aggregate size and compacted with a hand compactor or other mechanical means to
the maximum compaction possible. The bituminous concrete shall be compacted to ⅛ inch
above the finished pavement.
11. Acceptance Sampling and Testing: Sampling and testing shall be performed at a frequency
not less than the minimum frequency specified in Section M.04 and sub-article 4.06.03-10.
Sampling shall be performed in accordance with ASTM D 3665, or a statistically based
procedure of stratified random sampling approved by the Engineer.
Plant Material Acceptance: The Contractor shall provide the required sampling and testing
during all phases of the work in accordance with Section M.04. The Department will verify the
Contractor’s acceptance test results. Should any test results exceed the specified tolerances in
the Department’s current QA Program for Materials, the Contractor test results for a subject lot
or sub lot may be replaced with the Department’s results for the purpose of calculating
adjustments. The verification procedure is included in the Department’s current QA Program for
Materials.
Density Acceptance: The Engineer will perform all acceptance testing in accordance with
AASHTO T 331. The density of each core will be determined using the daily production’s

average maximum theoretical specific gravity (Gmm) established during the testing of the parent
material at the Plant. When there was no testing of the parent material or any Gmm exceeds the
specified tolerances in the Department’s current QA Program for Materials, the Engineer will
determine the maximum theoretical density value to be used for density calculations.
12. Density Dispute Resolution Process: The Contractor and Engineer will work in partnership
to avoid potential conflicts and to resolve any differences that may arise during quality control or
acceptance testing for density. Both parties will review their sampling and testing procedures
and results and share their findings. If the Contractor disputes the Engineer’s test results, the
Contractor must submit in writing a request to initiate the Dispute Resolution Process within 7
calendar days of the notification of the test results. No request for dispute resolution will be
allowed unless the Contractor provides quality control results within the timeframe described in
sub-article 4.06.03-9 supporting its position. No request for Dispute Resolution will be allowed
for a Density Lot in which any core was not taken within the required 5 calendar days of
placement. Should the dispute not be resolved through evaluation of existing testing data or
procedures, the Engineer may authorize the Contractor to obtain a new set of core samples per
disputed lot. The core samples must be extracted no later than 14 calendar days from the date of
Engineer’s authorization.
The number and location (mat, joint, or structure) of the cores taken for dispute resolution must
reflect the number and location of the original cores. The location of each core shall be
randomly located within the respective original sub lot. All such cores shall be extracted and the
core hole filled using the procedure outlined in Article 4.06.03. The dispute resolution results
shall be added to the original results and averaged for determining the final in-place density
value.

4.06.04—Method of Measurement:
1. HMA S* or PMA S*: The quantity of bituminous concrete measured for payment will be
determined by the documented net weight in tons accepted by the Engineer in accordance with
this specification and Section M.04.
2. Adjustments: Adjustments may be applied to bituminous concrete quantities and will be
measured for payment using the following formulas:
Yield Factor for Adjustment Calculation = 0.0575 Tons/SY/inch
Actual Area = [(Measured Length (ft)) x (Avg. of width measurements (ft))]
Actual Thickness (t) = Total tons delivered / [Actual Area (SY) x 0.0575 Tons/SY/inch]
a) Area: If the average width exceeds the allowable tolerance, an adjustment will be made
using the following formula. The tolerance for width is equal to the specified thickness
(in.) of the lift being placed.
Tons Adjusted for Area (TA) = [(L x Wadj)/9] x (t) x 0.0575 Tons/SY/inch = (-) Tons
Where: L = Length (ft)
(t) = Actual thickness (inches)
Wadj = (Designed width (ft) + tolerance /12) - Measured Width)
b) Thickness: If the actual average thickness is less than the allowable tolerance, the
Contractor shall submit a repair procedure to the Engineer for approval. If the actual
thickness exceeds the allowable tolerance, an adjustment will be made using the
following formula:
Tons Adjusted for Thickness (TT) = A x tadj x 0.0575 = (-) Tons
Where: A = Area = {[L x (Designed width + tolerance (lift thickness)/12)] / 9}
tadj = Adjusted thickness = [(Dt + tolerance) - Actual thickness]
Dt = Designed thickness (inches)

c) Weight: If the quantity of bituminous concrete representing the mixture delivered to the
project is in excess of the allowable gross vehicle weight (GVW) for each vehicle, an
adjustment will be made using the following formula:
Tons Adjusted for Weight (TW) = GVW – DGW= (-) Tons
Where: DGW = Delivered gross weight as shown on the delivery ticket or
measured on a certified scale.
d) Mixture Adjustment: The quantity of bituminous concrete representing the production
lot at the Plant will be adjusted as follow:
i. Non-PWL Production Lot (less than 3500 tons):
The adjustment values in Table 4.06-6 and 4.06-7 shall be calculated for each sub lot
based on the Air Void (AV) and Asphalt Binder Content (PB) test results for that sub
lot. The total adjustment for each day’s production (lot) will be computed using
tables and the following formulas:
Tons Adjusted for Superpave Design (TSD) = [(AdjAVt + AdjPBt) / 100] X Tons
Percent Adjustment for Air Voids = AdjAVt = [AdjAV1 + AdjAV2 + AdjAVi + … +
AdjAVn)] /n
Where: AdjAVt = Total percent air void adjustment value for the lot
AdjAVi = Adjustment value from Table 4.06-7 resulting from each sub
lot or the average of the adjustment values resulting from multiple tests
within a sub lot, as approved by the Engineer.
n = number of sub lots based on Table M.04.03-2

ii. PWL Production Lot (3500 tons or more):
For each lot, the adjustment values shall be calculated based on PWL for AV, VMA
and PB test results. The lot will be considered as being normally distributed and all
applicable equations in AASHTO R9 and AASHTO R42 Appendix X4 will apply.
Only one test result will be considered for each sub lot. The specification limits are
listed in Section M.04.
For AV, PB and voids in mineral aggregate (VMA), the individual material quality
characteristic adjustment (Adj) will be calculated as follow:
For PWL between 50 and 90%: Adj(AVt or PBt or VMAt)= (55 + 0.5 PWL) - 100
For PWL at and above 90%: Adj(AVt or PBt or VMAt)= (77.5 + 0.25 PWL) - 100
Where: AdjAVt = Total percent AV adjustment value for the lot
AdjPBt= Total percent PB adjustment value for the lot
AdjVMAt= Total percent VMA adjustment value for the lot
Lots with PWL less than 50% in any of the three individual material quality
characteristics will be evaluated under 1.06.04.
The total adjustment for each production lot will be computed using the following
formula:
Tons Adjusted for Superpave Design (TSD) = [(0.5AdjAVt + 0.25AdjPBt + 0.25
AdjVMAt) / 100] X Tons
iii. Partial Lots:
Lots with less than 4 sublots will be combined with the prior lot. If there is no prior
lot with equivalent material or if the last test result of the prior lot is over 30 calendar
days old, the adjustment will be calculated as indicated in 4.06.04-2.d.i.
Lots with 4 or more sublots will be calculated as indicated in 4.06.04-2.d.ii.

GENERAL
Mix status is defined as:
“A” – Approved:
Assigned to each mixture type from a production facility with a current rating of 70% or
greater, or to each mixture type completing a successful PPT.
“PPT” – Pre-Production Trial:
Temporarily assigned to each mixture type from a production facility when:
1. there are no compliant acceptance production test results submitted to the Department
from the previous year;
2. there is a source change in one or more aggregate components
3. there is a component percentage change of more than 5% by weight;
4. there is a change in RAP percentage;
5. the mixture has a rating of less than 70% from the previous season;
6. a new JMF not previously submitted.
Bituminous concrete mixtures with a “PPT” status cannot be used on Department projects.
Testing shall be performed by the Producer with NETTCP certified personnel on material
under this status. Test results must confirm that specifications requirements in Table M.04.02-
2 and Table M.04.02-5 are met before material can be used. One of the following methods
must be used to verify the test results:
Option A: Schedule a day when a Department Inspector can be at the facility to witness
testing or,
Option B: When the Contractor or their representative performs testing without being
witnessed by an Inspector, the Contractor shall submit the test results and a split sample
including 2 gyratory molds, 5,000 grams of boxed bituminous concrete, and 5,000 grams
of cooled loose bituminous concrete for verification testing and approval.
Option C: When the Contractor or their representative performs testing without being
witnessed by a Department Inspector, the Engineer may verify the mix in the Contractor’s
laboratory.
Witnessing or verifying by the Department of compliant test results will change the mix’s
status to an “A”.
The differences between the Department’s test results and the Contractor’s must be within the
“C” tolerances included in the Department’s QA Program for Materials, Acceptance and
Assurance Testing Policies and Procedures in order to be verified.

performing any QC functions on behalf of the Contractor. The QCP must also include a list of
sampling & testing methods and frequencies used during production, and the names of all Quality
Control personnel and their duties.
Approval of the QCP does not imply any warranty by the Engineer that adherence to the plan
will result in production of bituminous concrete that complies with these specifications. The
Contractor shall submit any changes to the QCP as work progresses.
2. Acceptance Requirements:
i. General:
Acceptance samples shall be obtained from the hauling vehicles and tested by the Contractor at
the Plant.
The Contractor shall submit all acceptance tests results to the Engineer within 24 hours or prior
to the next day’s production. All acceptance test specimens and supporting documentation must
be retained by the Contractor and may be disposed of with the approval of the Engineer. All
quality control specimens shall be clearly labeled and separated from the acceptance specimens.
Contractor personnel performing acceptance sampling and testing must be present at the facility
prior to, during, and until completion of production, and be certified as a NETTCP HMA Plant
Technician or Interim HMA Plant Technician and be in good standing. Production of material
for use on State projects must be suspended by the Contractor if such personnel are not present.
Technicians found by the Engineer to be non-compliant with NETTCP policies and procedures
or Department policies may be removed by the Engineer from participating in the acceptance
testing process for Department projects until their actions can be reviewed.
Anytime during production that testing equipment becomes defective or inoperable, production
can continue for a maximum of 1 hour. The Contractor shall obtain box sample(s) in accordance
with Table M.04.03-2 to satisfy the daily acceptance testing requirement for the quantity shipped
to the project. The box sample(s) shall be tested once the equipment issue has been resolved to
the satisfaction of the Engineer. Production beyond 1 hour may be considered by the Engineer.
Production will not be permitted beyond that day until the subject equipment issue has been
resolved.
Verification testing will be performed by the Engineer in accordance with the Department’s QA
Program for Materials.
Should the Department be unable to verify the Contractor’s acceptance test result(s) due to a
failure of the Contractor to retain acceptance test specimens or supporting documentation, the
Contractor shall review its quality control plan, determine the cause of the nonconformance and
Rev. Date 9/30/2016
English
GENERAL
respond in writing within 24 hours to the Engineer describing the corrective action taken. In
addition, the Contractor must provide supporting documentation or test results to validate the
subject acceptance test result(s). The Engineer may invalidate any adjustments for material
corresponding to the subject acceptance test(s). Failure of the Contractor to adequately address
quality control issues at a facility may result in suspension of production for Department projects
at that facility.
ii. Curb Mix Acceptance Sampling and Testing Procedures:
Curb Mix shall be tested in accordance to Table M.04.03-1 by the Contractor at a frequency of one
test per every 250 tons of cumulative production, regardless of the day of production.

a. Determination of Off-Test Status:
i. Curb Mix is considered “off test" when the test results indicate that any single value
for bitumen content or gradation are not within the tolerances shown in Table M.04.02-
1. If the mix is “off test”, the Contractor must take immediate actions to correct the
deficiency and a new acceptance sample shall be tested on the same day or the
following day of production.
ii. When multiple silos are located at one site, mixture supplied to one project is
considered as coming from one source for the purpose of applying the “off test” status.
iii. The Engineer may cease supply from the plant when test results from three consecutive
samples are not within the JMF tolerances or the test results from two consecutive
samples not within the control points indicated in Table M.04.02-1 regardless of
production date.
b. JMF revisions
Rev. Date 9/30/2016
English
GENERAL
i. If a test indicates that the bitumen content or gradation are outside the tolerances, the
Contractor may make a single JMF revision as allowed by the Engineer prior to any
additional testing. Consecutive test results outside the requirements of Table M.04.02-
1 JMF tolerances may result in rejection of the mixture.
ii. Any modification to the JMF shall not exceed 50% of the JMF tolerances indicated in
Table M.04.02-1 for any given component of the mixture without approval of the
Engineer. When such an adjustment is made to the bitumen, the corresponding
production percentage of bitumen shall be revised accordingly.
iii. Superpave Mix Acceptance:
a. Sampling and Testing Procedures
Production Lot: The Lot will be defined as one of the following types:
- Non-PWL Production Lot for total estimated project quantities per mixture less
than 3500 tons: All mixture placed during a single continuous paving operation.
- PWL Production Lot for total estimated project quantities per mixture of 3500 tons
or more: Each 3500 tons of mixture produced within 30 calendar days.
Production Sub Lot:
- For Non-PWL: As defined in Table M.04.03 – 2
- For PWL: 500 tons (the last Sub Lot may be less than 500 tons)
Partial Production Lots (For PWL only): A Lot with less than 3500 tons due to:
- completion of the Course
- a Job Mix Formula revision due to changes in:
o cold feed percentages over 5%
o target combined gradation over 5%
o target binder over 0.15%
o any component specific gravity
- a Lot spanning 30 calendar days
The acceptance sample(s) location(s) shall be selected using stratified – random sampling
in accordance with ASTM D 3665 based on:
- the total daily estimated tons of production for non-PWL lots, or
- the total lot size for PWL lots.
One acceptance sample shall be obtained and tested per Sub Lot. The Engineer may
direct that additional acceptance samples be obtained. For non-PWL lots, one acceptance
test shall always be performed in the last sub-lot based on actual tons of material
produced.
Rev. Date 9/30/2016

If the average ignition oven corrected binder content differs by 0.3% or more from the
average of the Plant ticket binder content in five (5) consecutive tests regardless of the
production date (moving average), the Contractor shall immediately investigate, determine
an assignable cause and correct the issue. When two consecutive moving average
differences are 0.3% or more and no assignable cause has been stablished, the Engineer
may require a new ignition oven aggregate correction factor to be performed or to adjust
the current factor by the average of the differences between the corrected binder content
and production Plant ticket for the last five (5) acceptance results.
Rev. Date 9/30/2016
English
GENERAL
The test specimen must be placed in an ignition oven for testing in accordance with
AASHTO T 308 within thirty minutes of being obtained from the hauling vehicle and the
test shall start immediately after.
The Contractor shall perform TSR testing within 30 days after the start of production for
all design levels of HMA- and PMA- S0.5 plant-produced mixtures, in accordance with
AASHTO T 283(M). The TSR test shall be performed at an AMRL certified laboratory by
NETTCP certified technicians. The compacted specimens may be fabricated at the Plant
and then tested at an AMRL accredited facility. The test results and specimens shall be
submitted to the Engineer for review. Superpave mixtures that require anti-strip additives
(either liquid or mineral) shall continue to meet all requirements specified herein for binder
and bituminous concrete. The Contractor shall submit the name, manufacturer, percent
used, technical datasheet and SDS for the anti-strip additive (if applicable) to the Engineer.
b. Determination of Off-Test Status:
i. Superpave mixes shall be considered “off test” when any Control Point Sieve, binder
content, VA, VMA, or Gmm value is outside of the limits specified in Table
M.04.03-4 or the target binder content at the Plant is below the minimum binder
content stated in Table M.04.02-5. Note that further testing of samples or portions of
samples not initially tested for this purpose cannot be used to change the status.
ii. Any time the bituminous concrete mixture is considered Off-test:
1. The Contractor shall notify the Engineer when the Plant is "off test" for any mix
design that is delivered to the project in any production day. When multiple silos
are located at one site, mixture supplied to one project is considered as coming from
one source for the purpose of applying the “off test” determination.
2. The Contractor must take immediate actions to correct the deficiency, minimize “off
test” production to the project, and obtain an additional Process Control (PC) test
after any corrective action to verify production is in conformance to the
specifications. A PC test will not be used for acceptance and is solely for the use of
the Contractor in its quality control process.
c. Cessation of Supply for Superpave Mixtures in non-PWL lots:
A mixture shall not be used on Department’s projects when it is “off test” for:
i. four (4) consecutive tests in any combination of VA, VMA or Gmm, regardless
of date of production, or,
ii. two (2) consecutive tests in the Control Point sieves in one production shift.
As a result of cessation of supply, the mix status will be changed to PPT.

GENERAL
d. JMF revisions:
JMF revisions are only permitted prior to or after a production shift. A JMF revision is
effective from the time it was submitted and is not retroactive to the previous test(s).
JMF revisions shall be justified by a documented trend of test results.
Revisions to aggregate and RAP specific gravities are only permitted when testing is
performed at an AMRL certified laboratory by NETTCP certified technicians.
A JMF revision is required when the Plant target RAP and/or bin percentage deviates
by more than 5% and/or the Plant target binder content deviates by more than 0.15%
from the active JMF.

ITEM NO. 0020805A – HANDLING ASBESTOS CONTAMINATED SOIL Description: Work under this Item is intended to provide specific procedural requirements to be followed by the Contractor during the excavation of asbestos contaminated soil and sediments (ACS) from within ACS areas of environmental concern (ACS AOECs), as shown on the Project Plans. This supplements Specifications Section 2.02, 2.03, 2.05, and 2.06 and Contract Special Provisions for excavation wherever ACS is encountered. Work under this item shall include transporting and stockpiling of ACS at the designated temporary waste stockpile areas (WSAs); and covering, securing, and maintaining the stockpiled materials throughout the duration of the Project. In addition, the work under this item may also include preparation of shipping containers, sealing loaded shipping containers as required for shipping asbestos waste, and transporting loaded and sealed shipping containers to a designated staging area. This item does not include ACS that is direct-loaded for transport for off-site disposal in accordance with Item No. 0020806A – Disposal of Asbestos Contaminated Soil. With the exception of decontaminated materials and materials previously imported for the creation of the east and west trestle ramps that are not in direct contact with the underlying ACS (as shown in Subset 07 - FOI of the Project Plans), all material excavated from the defined ACS AOECs are considered to be ACS. Where ACS is excavated, such material will not be reusable as backfill and will require special handling, storage, disposal and documentation procedures. Dewatering and/or solidification, if required, shall be performed in accordance with Item No. 00208007A – Dewatering and Solidification of Asbestos Contaminated Soil and Sediment. Note that ACS and other ACS-impacted materials (e.g., hay bales) are currently located within the existing Project WSA to the west of the Dock Access Road in Stratford that will need to be properly managed and disposed of as part of this Project before the WSA can be relocated to the new location shown on the plans. In addition, as part of the Project, there will be wooden piles that comprise the dolphin structure that will be removed and that cannot be adequately decontaminated. As such, these wooden piles will need to be disposed of as ACS-impacted materials. Any material processing (including, but not limited to the removal of scrap metal and resizing large stone, concrete, polyethylene sheeting or similar material) required by the Contractor’s selected facility will be completed by the Contractor prior to the material leaving the site. It is solely the Contractor’s responsibility to meet any such requirements of its facility. Materials: The required materials are detailed on the Project Plans. All materials shall conform to the requirements of the Contract.
• Polyethylene plastic sheeting for underlayment and covering excavated material shall be at least six (6) mils thick and at least three (3) meters wide.

lined with six (6) mil polyethylene sheeting and sealed to prevent contamination or leakage.
• Spray equipment for misting stockpiles in the WSA, as needed.
• No damaged or deteriorated materials shall be used. If material becomes contaminated
with ACS, the material shall be decontaminated or disposed of as asbestos-containing waste material.
• Runoff control barrier shall be constructed with hay bales (0.4 meters x 1 meter x 0.5
meters, typical).
• Sandbags used to secure polyethylene covers shall be at least 15 kilograms.
• Sorbent boom shall be 200 millimeters in diameter by 3 meters long and possess petrophilic and hydrophobic properties. Sorbent booms shall also have devices (i.e., clips, clasps, etc.) for connection to additional lengths of boom.
Construction Methods: A. General Health and safety provisions shall conform to the appropriate sections of the Contract. Provisions shall include air and personal monitoring, the use of chemical protective clothing (CPC), personal protective equipment (PPE), implementation of engineering controls as necessary, and decontamination procedures in accordance with Item No. 0101124A - Decontamination. All employees to be involved in ACS management shall have the necessary training, medical monitoring, and PPE as indicated in 29 Code of Federal Regulations (CFR) 1926.1101 and detailed in Contractor’s Health and Safety Plan, prepared in accordance with Item 0101021A – Environmental Health and Safety – Asbestos Contaminated Soil. Where practicable, ACS removed from any excavation within an ACS AOEC shall be transported directly from its point of origin on the Project to the nearest temporary WSA for the Project. The stockpiles of excavated ACS shall be maintained as shown on the Project Plans. The Contractor shall plan excavation activities within ACS AOECs in consideration of the capacity of WSA, the anticipated extent of material dewatering and/or solidification, and the material testing and disposal requirements of the applicable Contract item. No claims for delay shall be considered based on the Contractor’s failure to coordinate excavation activities as specified herein.

0138-0249 ITEM NO. 0020805A
Pre-characterization sampling of the ACS AOECs (specifically outside of the riverbed and banks) has been conducted to facilitate material disposal. Additional in-situ characterization shall be conducted as necessary by the Engineer. Sediments requiring dewatering and solidification will not be pre-characterized. When required, the Engineer will sample the stockpiled ACS at a frequency and for the constituents to meet the acceptance criteria of the treatment/recycling/disposal facilities submitted by the Contractor. The Contractor is hereby notified that laboratory turnaround time is expected to be fifteen (15) working days. Turnaround time is the period of time beginning when the Contractor notifies the Engineer which facility it intends to use and that the stockpile is ready for sampling and ending with the Contractor’s receipt of the laboratory analytical results. Any change of intended treatment/recycling/disposal facility may prompt the need to resample and will therefore restart the time required for laboratory turnaround. The laboratory will furnish such results to the Engineer. Upon receipt, the Engineer will make available to the Contractor the results of the final waste characterization determinations. No delay claim will be considered based upon the Contractor’s failure to accommodate the laboratory turnaround time as identified above. B. Transportation and Stockpiling In addition to following all pertinent Federal, State and local laws or regulatory agency policies, the Contractor shall adhere to the following precautions during transport of non-hazardous ACS:
• Transported ACS is to be covered prior to leaving the point of generation and is to remain covered until the arrival at the WSA;
• All vehicles departing the site are properly logged to show the vehicle identification,
driver’s name, time of departure, destination, and approximate volume and content of materials carried;
• All vehicles shall have secure, watertight containers free of defects for material
transportation; • No material shall leave the site until there is adequate lay down area prepared in the
WSA; and,
• Documentation must be maintained indicating that all applicable laws have been satisfied and that the materials have been successfully transported and received at the WSA.
• With the exception of the ACS area in Stratford (ACS AOEC 3 as shown on Project Plan
Sheet ENV-5) which underlies a proposed bin area, construction/relocation of the temporary WSA bins shall be completed prior to the initiation of construction activities generating ACS. Plastic polyethylene sheeting shall underlay all excavated ACS. Measures shall be implemented to divert rainfall away from the WSA bins. ACS AOEC 3 shall be fully excavated and placed in either one of the existing bins, a proper shipping container and sealed, or one of the newly constructed bins that does not conflict.

ITEM NO. 0101021A - ENVIRONMENTAL HEALTH AND SAFETY – ASBESTOS CONTAMINATED SOIL Description Under this Item, the Contractor shall establish protocols and provide procedures to protect the health and safety of its employees and subcontractors as related to the proposed construction activities performed within the Project Areas of Environmental Concern (AOECs) and across the Project Limits as a whole. This health and safety plan (HASP) shall also cover visitors to the site that have not prepared their own HASPs, and may include, but not be limited to, representatives of the Town of Stratford, the City of Milford, the Connecticut Department of Energy and Environmental Protection (CTDEEP), suppliers, truck drivers and easement holders. It shall also be sufficiently protective to prevent individuals from entering the Regulated Area and protect individuals outside the limits of a Regulated Area from being exposed to contaminants associated with the work. A “Regulated Area” is where airborne concentrations of asbestos exceed (or there is a reasonable possibility they may exceed) the OSHA permissible exposure limit (PEL) of 0.1 fibers per cubic centimeter based upon an 8 hour time weighted average (TWA). Said area(s) shall be demarcated such that the area is strictly controlled (authorized personnel only) and the people outside the area are protected from exposure. The Contractor shall refer to 29 Code of Federal Regulations (CFR) 1926.1101 for additional details. Work under this Item consists of the development and implementation of a written Health and Safety Plan (HASP) that addresses the relative risk of exposure to potential hazards, including, controlled materials, asbestos contaminated soil and sediment (ACS), and dewatering fluids present within Project Limits. As presented in the “Notice to Contractor – Asbestos Contaminated Soil and Environmental Investigations”, asbestos fibers have been found in soils within the Project Limits in Stratford and in sediments of the Housatonic River. Based on these findings, for health and safety purposes, the Contractor shall consider that asbestos fibers are present in soils, sediment, and dewatering fluids and prepare the HASP accordingly. The HASP shall establish health and safety protocols that address the relative risk of exposure to asbestos in accordance with the Occupational Health and Safety Administration (OSHA) asbestos regulations in 29 CFR 1926.1101 and regulated substances in accordance with 29 CFR 1910.120 and 29 CFR 1926.65. Such protocols shall address all regulatory provisions applicable to site conditions. The HASP developed by the Contractor, as indicated below, shall include provisions for site layout, security and control, with particular attention paid to the designation of Regulated Areas. The security shall include the consideration of appropriate methods for prevention of members of the public or otherwise unauthorized personnel from entering any portion of the site through the installation of physical barriers or other methods as site access controls. It shall further ensure that full coordination between the Project and the easement holders (UB Dockside, LLC and UB
10/04/17

ITEM NO. 0101117A - CONTROLLED MATERIAL HANDLING Description: Work under this Item is intended to provide specific procedural requirements to be followed by the Contractor during the excavation of Controlled Materials from within the Area of Environmental Concern (AOEC) that does not contain asbestos contaminated soil or sediment (ACS) as shown on the Project Plans. (Note that any area not designated as an ACS AOEC on the Project Plans shall be considered an AOEC.) This supplements Specifications Section 2.02, 2.03, 2.05, and 2.06 and Contract Special Provisions for excavation wherever contaminated materials are encountered. Work under this Item shall include transporting and stockpiling materials at the Waste Stockpile Areas (WSAs) (in bins either designated for non-ACS or in separate bins designated in some manner (e.g., caution tape) so as to prevent comingling of ACS materials with the non-ACS materials) and covering, securing, and maintaining the stockpiled materials throughout the duration of the Project. All materials, excluding the existing pavement structure (asphalt and subbase), rock, ledge, concrete and material previously imported for the creation of the east and west trestle ramps that is not in direct contact with the underlying ACS (as shown in Subset 07 - FOI of the Project Plans), excavated within AOECs are to be considered Controlled Materials. Controlled Materials consisting of non-hazardous levels of regulated substances (and that have not tested positive for asbestos fibers) have been documented to exist within the Project. Such contamination is documented in the reports listed in the “Notice to Contractor – Asbestos Contaminated Soil and Environmental Investigations.” Where contaminated soil is excavated, special handling, disposal, and documentation procedures will be required. All suitable Controlled Materials excavated within the AOECs may be reused as fill/backfill within the Project limits. Excess or unsuitable Controlled Material that cannot be reused within the Project limits, as determined by the Engineer, must be transported to and stockpiled in the WSAs, sampled by the Engineer, and transported off-site for disposal, if necessary. Materials: The required materials are detailed on the Project plans. All materials shall conform to the requirements of the Contract. Plastic Sheet: Polyethylene plastic sheeting for covering excavated material shall be a thickness of at least ten (10) mil and at least three (3) meters wide. Covers for roll-off/storage containers shall be made of polyethylene plastic, or similar water-tight material, that is of sufficient size to completely cover top opening and can be securely fastened to the container. Sand Bags: Sandbags used to secure polyethylene covers shall be at least fifteen (15) kilograms.

0138-0249 ITEM NO. 0101117A
Sorbent Boom: Shall be approximately two hundred (200) millimeters in diameter and three (3) meters long and possess petrophilic and hydrophilic properties. Sorbent booms shall also have devices (i.e., clips, clasps, etc.) for connection to additional lengths of boom. Construction Methods: A. General When Controlled Materials are encountered during the course of the work, health and safety provisions shall conform to the appropriate sections of the Contract. Provisions may include implementation of engineering controls, air and personal monitoring, the use of chemical protective clothing (CPC), personal protective equipment (PPE), and decontamination procedures. All suitable Controlled Material excavated from the AOECs may only be reused within the Project limits, as determined by the Engineer. Controlled Materials that are to be immediately reused within Project limits shall be temporarily stockpiled adjacent to the excavation for reuse. Controlled Materials that are to be reused at a later date within Project limits may be transported to the WSAs (non-ACS bins only) or temporarily stockpiled at another location within the Project limits as allowed by the Engineer. Only the volume of Controlled Material that is reasonably estimated to be reused within the Project limits shall be temporarily stockpiled in this way. Controlled Materials from individual AOECs to be reused at a later date shall be placed in separate stockpiles and shall not be intermingled with Controlled Materials from other AOECs, unless otherwise directed by the Engineer. Individual stockpiles of Controlled Materials that are to be reused at a later date shall be covered with polyethylene plastic sheeting at all times, except when the piles are being worked, and shall have proper erosion and sedimentation controls. Excess Controlled Material from an AOEC that cannot be reused within the Project limits must be transported directly to the WSAs and placed within a designated storage bin (for storage of non-ACS only) for disposal characterization sampling by the Engineer. The stockpiles of excavated Controlled Materials shall be maintained as shown on the Project plans. The Contractor shall plan excavation activities within the AOECs in consideration of the capacity of WSAs and the material testing and disposal requirements of the applicable Contract item. No claims for delay shall be considered based on the Contractor’s failure to coordinate excavation activities as specified herein. The Engineer will sample the Controlled Materials stockpiled within a WSA bin at a frequency and for the constituents to meet the acceptance criteria of the treatment/recycling/disposal facilities submitted by the Contractor. The Contractor is hereby notified that laboratory turnaround time is expected to be fifteen (15) working days. Turnaround time is the period of time beginning when the Contractor notifies the Engineer which facility it intends to use and that the stockpile is ready for sampling and ending with the Contractor’s receipt of the laboratory analytical results. Any change of intended treatment/recycling/disposal facility may prompt the
10/04/17
0138-0249 ITEM NO. 0101117A
need to resample and will therefore restart the time required for laboratory turnaround. The laboratory will furnish such results to the Engineer. Upon receipt, the Engineer will make available to the Contractor the results of the final waste characterization determinations. No delay claim will be considered based upon the Contractor’s failure to accommodate the laboratory turnaround time as identified above. B. Transportation and Stockpiling In addition to adhering to all pertinent Federal, State, and local laws or regulatory agency policies, the Contractor shall adhere to the following precautions during transport of non-hazardous materials: • Transported Controlled Materials are to be covered prior to leaving the point of generation
and are to remain covered until the arrival at a Project WSA;
• All vehicles departing the site are properly logged to show the vehicle identification, driver’s name, time of departure, destination, and approximate volume and content of materials carried;
• All vehicles shall have secure, watertight containers free of defects for material transportation;
• No Controlled Material shall be transported from the AOECs until there is adequate lay down area prepared in the WSA(s) or an area is prepared to stockpile the Controlled Material for later reuse within the Project limits; and,
• Documentation must be maintained indicating that all applicable laws have been satisfied and that the materials have been successfully transported and received at a Project WSA.
Construction of the WSAs and preparation of any temporary area(s) to stockpile Controlled Materials for reuse shall be completed prior to the initiation of construction activities generating Controlled Materials. Measures shall be implemented to divert rainfall away from the WSAs and away from temporary stockpiles of Controlled Materials to be reused. No Controlled Materials shall be excavated or transported to the WSAs until registration under the General Permit for Contaminated Soil and/or Sediment Management (Staging and Transfer) has been obtained by ConnDOT, if required. Placement of sorbent boom along the perimeter of the WSAs shall be conducted should the soil be saturated with petroleum product. Excavated materials shall be staged as shown on the Project plans or as directed by the Engineer. C. WSA Maintenance The Contractor shall provide all necessary materials, equipment, tools, and labor for anticipated activities within the WSAs. Such activities include, but are not limited to, handling and

management of stockpiles and drummed CPC/PPE; uncovering and recovering stockpiles; maintenance of WSAs; replacement of damaged components (i.e., sand bags, plastic polyethylene sheeting, etc.); and waste inventory record management. The Contractor shall manage all materials in the WSAs in such a way as to minimize tracking of potential contaminated materials across the site and off-site and minimize dust generation. Each stockpile shall be securely covered when not in active use with a cover of sufficient size to prevent generation of dust and infiltration of precipitation. The staged stockpiles shall be inspected at least daily by the Contractor to ensure that the cover and containment have not been damaged and that there is no apparent leakage from the piles. If the cover has been damaged, or there is evidence of leakage from the piles, the Contractor shall immediately replace the cover or containment as needed to prevent the release of materials to the environment from the piles. An inventory of stockpiled materials and drummed CPC/PPE shall be conducted on a daily basis. Inventory records shall indicate the approximate volume of material/drums stockpiled per day; the approximate volume of material/drums stockpiled to date; material/drums loaded and transported off-site for disposal; any materials loaded and transported for on-site reuse; and identification of stockpiles relative to their points of generation. Following the removal of all stockpiled Controlled Materials, residuals shall be removed from surfaces of the WSAs as directed by the Engineer. This operation shall be accomplished using dry methods such as shovels, brooms, mechanical sweepers, or a combination thereof. Residuals shall be disposed of as Controlled Materials. D. Dewatering Dewatering activities shall conform to items in pertinent articles of the Contract. E. Decontamination All equipment shall be provided to the work site free of contamination. The Engineer may prohibit from the site any equipment that in his opinion has not been thoroughly decontaminated prior to arrival. Any decontamination of the Contractor’s equipment prior to arrival at the site shall be at the expense of the Contractor. The Contractor is prohibited from decontaminating equipment on the Project that has not been thoroughly decontaminated prior to arrival. The Contractor shall furnish labor, materials, tools, and equipment for decontamination of all equipment and supplies that are used to handle Controlled Materials. Decontamination shall be conducted at an area designated by the Engineer and may be required prior to equipment and supplies leaving the Project, between stages of the work, or between work in different AOECs. Dry decontamination procedures are recommended. Residuals from dry decontamination activities shall be collected and managed as Controlled Materials. If dry methods are

The above list contains treatment/recycle/disposal facilities which can accept the waste stream generated by the Project in quantities that may be limited by their permits and their operational restrictions. It is the responsibility of the Contractor to verify that a facility will be available and capable of handling the volume as well as the chemical and physical characteristics of the material generated by the Project. Construction Methods: A. Material Disposal The Engineer will sample materials stored at the WSAs at a frequency established by the selected treatment/recycling/disposal facilities. The Contractor shall designate to the Engineer which facility(ies) it intends to use, as well as the facility acceptance criteria and sampling frequency, prior to samples being taken. The Contractor is hereby notified that laboratory turnaround time is expected to be fifteen (15) working days. Turnaround time is the period of time beginning when the Contractor notifies the Engineer which facility it intends to use and that a bin within the WSAs is full and ready for sampling, and ending with the Contractor’s receipt of the laboratory analytical results. Any change of intended treatment/recycling/disposal facility may prompt the need to resample and will therefore restart the time required for laboratory turnaround. The laboratory will furnish such results to the Engineer. Upon receipt, the Engineer will make available to the Contractor the results of the final waste characterization determinations. No delay claim will be considered based upon the Contractor’s failure to accommodate the laboratory turnaround time as identified above. The Contractor shall obtain and complete all paperwork necessary to arrange for material disposal (such as disposal facility waste profile sheets). It is solely the Contractor’s responsibility to co-ordinate the disposal of Controlled Materials with its selected treatment/recycling/disposal facility(ies). Upon receipt of the final approval from the facility, the Contractor shall arrange for the loading, transport and treatment/recycling/disposal of the materials in accordance with all Federal and State regulations. No claim will be considered based on the failure of the Contractor’s selected disposal facility(ies) to meet the Contractor’s production rate or for the Contractor’s failure to select sufficient facilities to meet its production rate. Any material processing (including but not limited to the removal of woody debris, scrap metal, pressure-treated and untreated wood timber, large stone, concrete, polyethylene sheeting or similar material) required by the Contractor’s selected facility will be completed by the Contractor prior to the material leaving the site. It is solely the Contractor’s responsibility to meet any such requirements of its facility. Any materials removed shall be disposed of or recycled in a manner acceptable to the Engineer at no additional cost. All manifests or bills of lading utilized to accompany the transportation of the material shall be prepared by the Contractor and signed by an authorized Department representative, as Generator, for each truck load of material that leaves the site. The Contractor shall forward the appropriate original copies of all manifests or bills of lading to the Engineer the same day the material leaves

the Project. A load-specific certificate of treatment/recycling/disposal, signed by the authorized agent representing the disposal facility, shall be obtained by the Contractor and promptly delivered to the Engineer for each load. B. Material Transportation In addition to all pertinent Federal, State and local laws or regulatory agency policies, the Contractor shall adhere to the following precautions during the transport of Controlled Materials off-site:
1. Transported Controlled Materials are to be covered sufficiently to preclude the loss of material during transport prior to leaving the site and are to remain covered until their arrival at the selected treatment/recycling/disposal facility.
2. All vehicles departing the site are to be properly logged to show the vehicle
identification, driver’s name, time of departure, destination, and approximate volume and contents of materials carried.
3. No materials shall leave the site unless a treatment/recycling/disposal facility willing to
accept all of the material being transported has agreed to accept the type and quantity of waste.
C. Equipment Decontamination All equipment shall be provided to the work site free of gross contamination. The Engineer may prohibit from the site any equipment that in his opinion has not been thoroughly decontaminated prior to arrival. Any decontamination of the Contractor’s equipment prior to arrival at the site shall be at the expense of the Contractor. The Contractor is prohibited from decontaminating equipment on the Project that has not been thoroughly decontaminated prior to arrival. The Contractor shall furnish labor, materials, tools and equipment for decontamination of all equipment and supplies that are used to handle Controlled Materials. Decontamination shall be conducted at an area designated by the Engineer and shall be required prior to equipment and supplies leaving the Project, between stages of the work, and between work in different Project areas. The Contractor shall use dry decontamination procedures. Residuals from dry decontamination activities shall be collected and managed as Controlled Materials. If the results from dry methods are unsatisfactory to the Engineer, the Contractor shall modify decontamination procedures as required. The Contractor shall be responsible for the collection and treatment/recycling/disposal of any liquid wastes that may be generated by its decontamination activities in accordance with applicable regulations.

0138-0249 ITEM NO. 0202315A
Method of Measurement: The work of “Disposal of Controlled Materials” will be measured for payment as the actual net weight in metric tons of material delivered to the treatment/recycling/disposal facility. Such determinations shall be made by measuring each hauling vehicle on the certified permanent scales at the treatment/recycling/disposal facility. Total weight will be the summation of weight bills issued by the facility specific to this Project. Excess excavations made by the Contractor beyond the payment limits specified in Specification Sections 2.02, 2.03, 2.05, 2.06, or the Contract Special Provisions (as appropriate), will not be measured for payment and the Contractor assumes responsibility for all costs associated with the appropriate handling, management and disposal of this material. The disposal of excavated materials, originally anticipated to be Controlled Materials, but determined by characterization sampling not to contain concentrations of regulated chemicals (non-polluted or “clean” materials) will not be measured for payment under this item but will be considered as surplus excavated materials and will be paid in accordance with Article 1.04.05. Any materials stored in the WSAs, and which are reused within Project limits, will not be measured for payment under this Item. This material will be paid for in accordance with Article 1.04.05. Equipment decontamination, the collection of residuals, and the collection and disposal of liquids generated during equipment decontamination activities, will not be measured separately for payment. Any material processing required by the Contractor-selected disposal facility(ies), including the proper disposal of all removed materials, will not be measured for payment. Basis of Payment: This work will be paid for at the Contract unit price, which shall include the loading and transportation of Controlled Materials from the WSAs to the treatment/recycling/disposal facility; the fees paid to the facility for treatment/recycling/disposal; the preparation of all related paperwork; and all equipment, materials, tools, and labor incidental to this work. This unit price will be applicable to all of the listed disposal facilities and will not change for the duration of the Project. This price shall also include equipment decontamination; the collection of residuals generated during decontamination and placement of such material in the WSA; and the collection and disposal of liquids generated during equipment decontamination activities.

As indicated in the “Notice to Contractor – Asbestos Contaminated Soil and Environmental Investigations,” some soil and sediments to be excavated within the Project Limits have been demonstrated to contain asbestos. Environmental investigations have also identified the presence of other constituents of concern including total and leachable arsenic and lead, leachable chromium, ETPH, PAHs and select VOCs. Wastewater generated during dewatering of ACS may also contain those contaminants of concern and will therefore require special provisions for management and disposal. The specific activities that generate the subject wastewater will be managed under separate items, including Item Nos. 0020807A – Dewatering and Solidification of Asbestos Contaminated Soil and Sediment and 0101124A - Decontamination. The Contractor shall design, furnish, install, and operate a coordinated system that provides for the temporary containment of contaminated wastewater encountered or generated during construction operations (i.e., free draining liquid from excavated ACS, water from dewatering activities during construction, and decontamination water). After temporary containment, the Contractor shall either: (1) transport the wastewater off-site to be disposed of at a Department-approved, permitted disposal facility (Option 1), or (2) treat the contaminated wastewater and discharge to the sanitary sewer, as authorized by the Connecticut Department of Energy and Environmental Protection (CTDEEP), local municipality, and/or utility company (Option 2). This Item does not apply to the possible diversion of existing storm water flow around the construction site during Project activities. Diversion of existing storm water or surface flows shall be completed in accordance with the Contract and all applicable permits. Construction Methods:

ITEM #0948013A – TIDAL WETLAND CREATION
Description:
The work shall consist of the construction of a Tidal Creation, Tidal Restoration or Tidal
Enhancement area (“mitigation area”) at the site(s) identified on the Tidal Wetland Mitigation
Plans. The work generally consists of excavating, backfilling, and preparing appropriate site grades
under the direction of an Environmental Inspector from the Connecticut Department of
Transportation’s Office of Environmental Planning (OEP).
Materials:
Planting Soil : Natural or manmade planting substrate or topsoil may be used, which shall consist
of soils containing no less than 75% sand by weight and an organic content no less than 10% and
no more than 15%. The soil must be analyzed by USDA-approved methodology for organic matter
by loss-on-ignition of oven-dried samples dried at 105 degrees centigrade. The mineral fraction
must be analyzed to determine weight percentage of sand, as determined after passing a 2-
millimeter (mm) sieve. Sand particles are defined to be between 0.05 and 2.0 mm in diameter.
The topsoil must be free of seeds and roots of invasive species and inspected and approved by the
Connecticut Department of Transportation Office of Environmental Planning (CT DOT OEP)
prior to its application.
Planting soil not furnished by the Contractor shall be native soil material from areas free of
invasive species stripped from permitted earth excavation areas within the project limits if it meets
the criteria described above and the Certified Material test results are approved by OEP. If these
soils do not meet the criteria, additional make-up material from off-site areas may be substituted
or mixed with the on-site project material provided the resultant soil composition meets the
applicable criteria. Clean leaf compost is the preferred soil amendment to achieve the organic
content criteria. If other soil amendments are more readily available than clean leaf compost they
can be used to meet the requirement for organic content.
The soils must be analyzed by USDA-approved methodology for organic matter by loss-on-
ignition of oven-dried samples dried at 105 degrees centigrade. The mineral fraction must be
analyzed to determine weight percentage of sand, as determined after passing a 2-millimeter (mm)
sieve. Sand particles are defined to be between 0.05 and 2.0 mm in diameter. Certified Materials
Test results are to be submitted to OEP for approval. The soils must be free of seeds and roots of
invasive species and inspected and approved by OEP prior to their application.
If soil must be supplemented with organic material, the following sources are acceptable but must
meet the specification of planting soil described above:
a) Native Wetland Soil: The top layer of native wetland soil excavated from within the
project limits or from another permitted wetland source. The bottom of this layer shall be
defined as the depth at which the soil color and texture changes, indicating the beginning
rev. 4/29/2015
ITEM #0948013A
of the subsoil. Each source must be inspected in place at least 6 months prior to excavation
and determined by OEP to be free from seeds and roots of invasive species.
b) Compost: Compost shall meet the requirements of Subarticle M.13.06 – Compost.
c) Peat: Peat shall meet the requirements of Subarticle M.13.07 – 13 – Peat. Peat material
excavated from the project site may be substituted for commercially packaged peat, at the
discretion of the Engineer, if the on-site peat meets all the requirements of the specification.
Backfill: Backfill used in the Tidal Wetland Mitigation Area shall be native or manmade material.
Backfill shall consist of soils meeting the textural classification of silt loam and consist of greater
than 50% silt; the percentage of clay is typically less than 25%. The soils must be analyzed by
USDA-approved methodology. The mineral fraction must be analyzed to determine the particle
gradation to meet the above textural requirement. Certified Materials Test results are to be
submitted to OEP for approval. The soils must be free of seeds and roots of invasive species and
inspected and approved by OEP prior to their use and application.
Construction Methods:
An Environmental Inspector from OEP will be on-site to monitor construction of the Tidal
Wetland Mitigation Area(s) to ensure compliance with the Tidal Wetland Mitigation Plans.
The Contractor shall submit a construction schedule and an outline of construction methodologies
for the required earthwork of the tidal wetland creation site according to the general construction
sequence and requirements outlined below to OEP for approval. No work associated with the
Wetland Mitigation Area(s) shall commence until OEP approval is granted. OEP shall have 30
days from the date the submission is received from District Construction to review and approve
the submission. The Contractor must schedule wetland creation activities to begin as soon as access
allows. There shall be no inactive period of longer than 10 days between the beginning of the
excavation of the mitigation site and the time which final grades are reached. When applicable,
and when conditions warrant, excavation and final grading shall be completed during and near
times of low tide only unless the work area is contained and isolated from tidal action. The
excavation, final grading, seeding and planting shall be scheduled so that planting will occur within
an approved planting season. Upon completion of final grades, the site shall be exposed to tidal
flushing for a minimum of 7 days and a maximum of 14 days to allow for settlement of the planting
soil and to evaluate final grades. At the end of the first 7 days, the site conditions will be evaluated
by an Environmental Inspector from OEP. Adjustments to final grades or additional placement of
planting soil may be made at this time. Planting of rootstock is to immediately follow the
maximum 14 day period.
During the performance of this work, a CT DOT Environmental Inspector from OEP will be
available to visit the site to direct the construction activities involved in constructing the wetland
creation sites. The Contractor shall arrange through the engineer at least 10 days prior to the
commencement of these activities to ensure that the Environmental Inspector is available. OEP
reserves the option to adjust the mitigation site Final Grading and Planting Plans to ensure
mitigation site success. During Planting, a qualified wetland professional (or OEP

(3) Setting Plants: Setting Plants: All planting within the Wetland Mitigation Area(s) shall
conform to the following additional requirements:
(a) – Setting of herbaceous stock in Wetland Areas: Herbaceous stock shall be planted
within planting cells, or clusters, such that individual plants of the same species are grouped
together within each cell, at the spacings directed by a member of the CT DOT OEP. All
plants shall be set manually. The placement of the cells shall be identified in the field and
approved by a member of the CT DOT OEP.
During planting, a member of the CT DOT OEP may relocate up to 50% of the planting
cells, from the locations identified in the field or shown on the plans, if as-built site
conditions would pose an unreasonable threat to the survival of plantings installed according
to the mitigation plan. The planting cells shall be relocated to locations with suitable
hydrology and soils and where appropriate structural context with other planting cells can be
maintained. The term planting cells means the discrete clusters of plants shown on the
approved planting plan. If plant species are not planted in discrete clusters, the planting cell
is the entire mitigation site.
(b) – Setting of Shrub Plants in the Wetland Area: All shrub plants in the Tidal Wetland
Mitigation Area shall be set as to be level with the microtopography of that immediate area.
Shrubs will be irregularly placed within a planting cell, at a minimum spacing specified in the
Planting Schedule. For each species, the number of plants shall be as indicated in the Planting
Schedule.
(4) Fertilizing: Do not fertilize plantings within the Tidal Wetland Mitigation Area(s).

site for the presence of invasive species including, but not limited to phragmites, purple
loosetrife, autumn olive, Multiflora rose, Morrow’s and Tartarian honeysuckle and reed
canary grass. If such species are found, the Contractor must use mechanical methods for
removal of all invasive plants from within the Tidal Wetland Mitigation Area, including
all roots.
Rev. 9/27/17
ITEM # 0949029A
If a member of the CT DOT OEP determines that the mechanical removal methods have
been unsuccessful, the Contractor shall employ a licensed herbicide applicator to treat these
individual plants with glyphosphate-based herbicide or other approved equivalent to
control and/or eliminate such species from the mitigation area. The herbicide RoundupTM
shall not be used in or near wetlands because the surfactant in RoundupTM is believed to
harm wetland invertebrates. Instead, RodeoTM or other appropriate options shall be used if
required.

TRAFFIC CONTROL DURING CONSTRUCTION OPERATIONS (Metric Version)
The following guidelines shall assist field personnel in determining when and what type of traffic
control patterns to use for various situations. These guidelines shall provide for the safe and
efficient movement of traffic through work zones and enhance the safety of work forces in the
work area.
Rev. 9/27/17
ITEM #0971001A
TRAFFIC CONTROL PATTERNS: Traffic control patterns shall be used when a work
operation requires that all or part of any vehicle or work area protrudes onto any part of a travel
lane or shoulder. For each situation, the installation of traffic control devices shall be based on the
following:
Speed and volume of traffic
Duration of operation
Exposure to hazards
Traffic control patterns shall be uniform, neat and orderly so as to command respect from the
motorist.
In the case of a horizontal or vertical sight restriction in advance of the work area, the traffic control
pattern shall be extended to provide adequate sight distance for approaching traffic.
If a lane reduction taper is required to shift traffic, the entire length of the taper should be installed
on a tangent section of roadway so that the entire taper area can be seen by the motorist.
Any existing signs that are in conflict with the traffic control patterns shall be removed, covered,
or turned so that they are not readable by oncoming traffic.
When installing a traffic control pattern, a Buffer Area should be provided and this area shall be
free of equipment, workers, materials and parked vehicles.
Typical traffic control plans 20 through 25 may be used for moving operations such as line striping,
pot hole patching, mowing, or sweeping when it is necessary for equipment to occupy a travel
lane.
Traffic control patterns will not be required when vehicles are on an emergency patrol type activity
or when a short duration stop is made and the equipment can be contained within the shoulder.
Flashing lights and appropriate trafficperson shall be used when required.
Although each situation must be dealt with individually, conformity with the typical traffic control
plans contained herein is required. In a situation not adequately covered by the typical traffic
control plans, the Contractor must contact the Engineer for assistance prior to setting up a traffic
control pattern.
PLACEMENT OF SIGNS: Signs must be placed in such a position to allow motorists the
opportunity to reduce their speed prior to the work area. Signs shall be installed on the same side
of the roadway as the work area. On multi-lane divided highways, advance warning signs may be
installed on both sides of the highway. On directional roadways (on-ramps, off-ramps, one-way
roads), where the sight distance to signs is restricted, these signs should be installed on both sides
of the roadway.
Rev. 9/27/17
ITEM #0971001A
Allowable Adjustment of Signs and Devices
Shown on the Traffic Control Plans
The traffic control plans contained herein show the location and spacing of signs and devices under
ideal conditions. Signs and devices should be installed as shown on these plans whenever possible.
The proper application of the traffic control plans and installation of traffic control devices depends
on actual field conditions.
Adjustments to the traffic control plans shall be made only at the direction of the Engineer to
improve the visibility of the signs and devices and to better control traffic operations. Adjustments
to the traffic control plans shall be based on safety of work forces and motorists, abutting property
requirements, driveways, side roads, and the vertical and horizontal curvature of the roadway.
The Engineer may require that the traffic control pattern be located significantly in advance of the
work area to provide better sight line to the signing and safer traffic operations through the work
zone.
Table I indicates the minimum taper length required for a lane closure based on the posted speed
limit of the roadway. These taper lengths shall only be used when the recommended taper lengths
shown on the traffic control plans cannot be achieved.

SECTION 1. WORK ZONE SAFETY MEETINGS
1.a) Prior to the commencement of work, a work zone safety meeting will be conducted with
representatives of DOT Construction, Connecticut State Police (Local Barracks),
Municipal Police, the Contractor (Project Superintendent) and the Traffic Control
Subcontractor (if different than the prime Contractor) to review the contract requirements
and discuss the Department’s procedures. Other work zone safety meetings during the
course of the project should be scheduled as needed.
1.b) A Work Zone Safety Meeting Agenda, (see Section 9), shall be developed and used at the
meeting to outline the anticipated traffic control issues during the construction of this
project. Any issues that can’t be resolved at these meetings will be brought to the attention
of the District Engineer and the Office of Construction.
Rev. 9/27/17
ITEM #0971001A
SECTION 2. INSTALLING AND REMOVING TRAFFIC CONTROL PATTERNS
2.a) Lane Closures shall be installed beginning with the advanced warning signs and proceeding
forward toward the work area.
2.b) Lane Closures shall be removed in the reverse order, beginning at the work area, or end of
the traffic control pattern, and proceeding back toward the advanced warning signs.
2.c) Stopping traffic may be allowed:
• As per the contract for such activities as blasting, steel erection, etc.
• During paving, milling operations, etc. where, in the middle of the operation, it is
necessary to flip the pattern to complete the operation on the other half of the
roadway and traffic should not travel across the longitudinal joint or difference in
roadway elevation.
• To move slow moving equipment across live traffic lanes into the work area.
2.d) Under certain situations when the safety of the traveling public and/or that of the workers
may be compromised due to conditions such as traffic volume, speed, roadside
obstructions, or sight line deficiencies, as determined by the Engineer and/or State Police,
traffic may be briefly impeded while installing and/or removing the advanced warning
signs and the first ten traffic cones/drums only. Appropriate measures shall be taken to
safely slow traffic. If required, State Police may use traffic slowing techniques, including
the use of Truck Mounted Impact Attenuators (TMAs) as appropriate, for a minimum of
1.6 km in advance of the pattern starting point. Once the advanced warning signs and the
first ten traffic cones/drums are installed/removed, the two TMAs and sign crew should
continue to install/remove the pattern as described in Section 4c and traffic shall be allowed
to resume their normal travel.
2.e) The Contractor must adhere to using the proper signs, placing the signs correctly, and
ensuring the proper spacing of signs.
2.f) Additional devices are required on entrance ramps, exit ramps, and intersecting roads to
warn and/or move traffic into the proper travelpath prior to merging/exiting with/from the
main line traffic. This shall be completed before installing the mainline pattern past the
ramp or intersecting roadway.
2.g) Prior to installing a pattern, any conflicting existing signs shall be covered with an opaque
material. Once the pattern is removed, the existing signs shall be uncovered.
2.h) On limited access roadways, workers are prohibited from crossing the travel lanes to install
and remove signs or other devices on the opposite side of the roadway. Any signs or
devices on the opposite side of the roadway shall be installed and removed separately.
SECTION 3. USE OF HIGH MOUNTED INTERNALLY ILLUMINATED FLASHING
ARROW
3.a) On limited access roadways, one Flashing Arrow shall be used for each lane that is closed.
The Flashing Arrow shall be installed concurrently with the installation of the traffic
control pattern and its placement shall be as shown on the traffic control plan. For multiple
Rev. 9/27/17
ITEM #0971001A
lane closures, one Flashing Arrow is required for each lane closed. If conditions warrant,
additional Flashing Arrows should be employed (i.e.: curves, major ramps, etc.).
3.b) On non-limited access roadways, the use of a Flashing Arrow for lane closures is optional.
The roadway geometry, sight line distance, and traffic volume should be considered in the
decision to use the Flashing Arrow.
3.c) The Flashing Arrow shall not be used on two lane, two-way roadways for temporary
alternating one-way traffic operations.
3.d) The Flashing Arrow board display shall be in the “arrow” mode for lane closure tapers and
in the “caution” mode (four corners) for shoulder work, blocking the shoulder, or roadside
work near the shoulder. The Flashing Arrow shall be in the “caution” mode when it is
positioned in the closed lane.
3.e) The Flashing Arrow shall not be used on a multi-lane roadway to laterally shift all lanes of
traffic, because unnecessary lane changing may result.
3.f) If the required number of Flashing Arrows is not available, the traffic control pattern shall
not be installed.
SECTION 4. USE OF TRUCK MOUNTED IMPACT ATTENUATOR VEHICLES
(TMAs)
4.a) For lane closures on limited access roadways, a minimum of two TMAs shall be used to
install and remove traffic control patterns. If two TMAs are not available, the pattern shall
not be installed.
4.b) On non-limited access roadways, the use of TMAs to install and remove patterns closing a
lane(s) is optional. The roadway geometry, sight line distance, and traffic volume should
be considered in the decision to utilize the TMAs.
4.c) Generally, to establish the advance and transition signing, one TMA shall be placed on the
shoulder and the second TMA shall be approximately 300 meters ahead blocking the lane.
The flashing arrow board mounted on the TMA should be in the “flashing arrow” mode
when taking the lane. The sign truck and workers should be immediately ahead of the
second TMA. In no case shall the TMA be used as the sign truck or a work truck. Once
the transition is in place, both TMAs shall travel in the closed lane until all Changeable
Message Signs, signs, Flashing Arrows, and cones/drums are installed. The flashing arrow
board mounted on the TMA should be in the “caution” mode when traveling in the closed
lane.
4.d) A TMA shall be placed prior to the first work area in the pattern. If there are multiple work
areas within the same pattern, then additional TMAs may be positioned at each additional
work area as needed. The flashing arrow board mounted on the TMA should be in the
“caution” mode when in the closed lane.
4.e) TMAs shall be positioned a sufficient distance prior to the workers or equipment being
protected to allow for appropriate vehicle roll-ahead in the event that the TMA is hit, but
not so far that an errant vehicle could travel around the TMA and into the work area. For
Rev. 9/27/17
ITEM #0971001A
additional placement and use details, refer to the specification entitled “Type ‘D’ Portable
Impact Attenuation System”. Some operations, such as paving and concrete repairs, do
not allow for placement of the TMA(s) within the specified distances. In these situations,
the TMA(s) should be placed at the beginning of the work area and shall be advanced as
the paving or concrete operations proceed.
4.f) TMAs should be paid in accordance with how the unit is utilized. When it is used as a
TMA and is in the proper location as specified, then it should be paid at the specified hourly
rate for “Type ‘D’ Portable Impact Attenuation System”. When the TMA is used as a
Flashing Arrow, it should be paid at the daily rate for “High Mounted Internally Illuminated
Flashing Arrow”. If a TMA is used to install and remove a pattern and then is used as a
Flashing Arrow, the unit should be paid as a “Type ‘D’ Portable Impact Attenuation
System” for the hours used to install and remove the pattern, typically 2 hours (1 hour to
install and 1 hour to remove), and is also paid for the day as a “High Mounted Internally
Illuminated Flashing Arrow”.
4.g) If the required number of TMAs is not available, the pattern shall not be installed.
SECTION 5. USE OF STATE POLICE OFFICERS
5.a) On limited access highways, the Engineer may determine that State Police Officers will be
utilized for regional work zone traffic safety and enforcement operations in addition to
project-related work zone assignments. State Police Officers shall be uniformed off-duty
sworn Connecticut State Police Officers. Their services will also include the use of official
State Police vehicles and associated equipment. State Police Officers will be used on all
limited access highways. State Police Officers will not be used on non-limited access
highways unless specifically under their jurisdiction or authorized in writing by the
Engineer. State Police Officers with official State Police vehicles will be used at such
locations and for such periods as the Engineer deems necessary to control traffic operations
and promote increased safety to motorists through the construction sites.
5.b) On a weekly basis, the Contractor shall submit to the Engineer the state police request form
(DPS-0691-C) as an indication of their scheduled operations for the following week. This
form shall be submitted no later than Wednesday Morning of the week prior to the
scheduled operations. The Engineer shall review this schedule and approve the type and
number of Officers required by signing off under the “Completed by DOT’s Authorized
Representative” line on Department of Public Safety Form DPS-0691-C. Once the
Engineer has approved the number of Officers requested the Engineer will fax the order to
the Department of Public Safety’s Overtime Office.
5.c) Prior to the start of operations, a meeting will be held with the Contractor, Trooper in
charge and Engineer to review the Trafficperson operations, lines of responsibility, and
operating guidelines which will be used for the scheduled work.
5.d) At least one Officer should be used per critical sign pattern. Shoulder closures and right
lane closures can generally be implemented without the presence of a State Police Officer.
Likewise in areas with moderate traffic and wide, unobstructed medians, left lane closures
can be implemented without State Police presence. Certain situations may require State
Police presence, if one is available, even though the general guidelines above indicate
Rev. 9/27/17
ITEM #0971001A
otherwise. Examples of this include: nighttime lane closures; left lane closures with
minimal width for setting up advance signs and staging; lane and shoulder closures on
turning roadways/ramps or mainline where sight distance is minimal; and closures where
extensive turning movements or traffic congestion regularly occur.
5.e) Once the pattern is in place, the State Police Officer should be positioned in a non-
hazardous location at the beginning of the pattern or at one of the work areas not protected
by a TMA. If traffic backs up beyond the beginning of the pattern, then the State Police
Officer should be repositioned prior to the backup to give warning to the oncoming
motorists. Where State Police Officer and TMA are in close proximity to each other, the
TMA should be placed to protect the State Police Officer’s vehicle from oncoming traffic.
5.f) Other functions of the State Police Officer(s) shall include:
• *Assisting entering/exiting construction vehicles within the work area.
• *Enhancing worker visibility/safety for workers in close proximity to the open
travel lane(s).
• Speed control of traffic within the work area.
• Enforcement of speed and other motor vehicle laws within the work area.
Typically, the State Police Officer should be out of the vehicle for the functions marked
with an asterisk (*).
5.g) State Police Officers assigned to a work site are to only take direction from the Engineer.

SECTION 6. USE OF (REMOTE CONTROLLED) CHANGEABLE MESSAGE SIGNS
6.a) For lane closures on limited access roadways, one Changeable Message Sign shall be used
in advance of the traffic control pattern. Prior to installing the pattern, the Changeable
Message Sign shall be installed and in operation, displaying the appropriate lane closure
information (i.e.: Left Lane Closed - Merge Right). The Changeable Message Sign shall
be positioned 800 – 1600 meters ahead of the lane closure taper. If the nearest Exit ramp
is greater than the specified 800 – 1600 meter distance, then an additional Changeable
Message Sign shall be positioned a sufficient distance ahead of the Exit ramp to alert
motorists of the lane closure and provide them an opportunity to take the exit.
6.b) On non-limited access roadways, the use of Changeable Message Signs for lane closures
is optional. The roadway geometry, sight line distance, and traffic volume should be
considered in the decision to use the Changeable Message Sign.
6.c) The advance Changeable Message Sign is typically placed off the right shoulder, 1.5 meters
from the edge of pavement. In areas where the Changeable Message Sign cannot be placed
beyond the edge of pavement, it may be placed on the paved shoulder with a minimum of
Rev. 9/27/17
ITEM #0971001A
five (5) traffic drums placed in a taper in front of it to delineate its position. The advance
Changeable Message Sign shall be adequately protected if it is used for a continuous
duration of 36 hours or more.
6.d) When the Changeable Message Signs are no longer required, they should be removed from
the clear zone and have the display screen cleared and turned 90° away from the roadway.
6.e) The Changeable Message Sign generally should not be used for generic messages (ex:
Road Work Ahead, Bump Ahead, Gravel Road, etc.).
6.f) The Changeable Message Sign should be used for specific situations that need to command
the motorist’s attention which cannot be conveyed with standard construction signs
(Examples include: Exit 34 Closed Sat/Sun - Use Exit 35, All Lanes Closed - Use Shoulder,
Workers on Road - Slow Down).
6.g) Messages that need to be displayed for long periods of time, such as during stage
construction, should be displayed with construction signs. For special signs, please
coordinate with the Office of Construction and the Division of Traffic Engineering for the
proper layout/dimensions required.
6.h) Section 11 contains the messages that are allowed on the Changeable Message Sign. For
any other message(s), approval must be received from the Office of Construction prior to
their use. No more than two (2) displays shall be used within any message cycle.
6.i) If the required number of Changeable Message Signs is not available, the pattern shall not
be installed.
SECTION 7. USE OF (REMOTE CONTROLLED) CHANGEABLE MESSAGE SIGNS
WITH RADAR
7.a) (Remote Controlled) Changeable Message Signs with Radar shall be used when
specified, or as directed by the Engineer.
7.b) The typical placement of a (Remote Controlled) Changeable Message Sign with Radar is
in the work zone portion of the traffic control pattern.
7.c) The typical usage of the (Remote Controlled) Changeable Message Sign with Radar is to
display a message when a preset speed is exceeded. The sign will blank when no vehicles
are present.
7.d) The preset speed for activating the message should be set 5-10 MPH above the posted, or
desired, speed.
7.e) Section 12 contains the messages that are allowed on the (Remote Controlled) Changeable
Message Sign with Radar. For any other message(s), approval must be received from the
Office of Construction prior to their use. No more than two (2) displays shall be used within
any message cycle.
SECTION 8. USE OF TRAFFIC DRUMS AND TRAFFIC CONES
Rev. 9/27/17
ITEM #0971001A
8.a) Traffic drums shall be used for taper channelization on limited-access roadways, ramps,
and turning roadways and to delineate raised catch basins and other hazards.
8.b) Traffic drums shall be used in place of traffic cones in traffic control patterns that are in
effect for more than a 72-hour duration.
8.c) Traffic Cones less than 1 meter in height shall not be used on limited-access roadways or
on non-limited access roadways with a posted speed limit of 45 mph and above.
8.d) Typical spacing of traffic drums and/or cones shown on the Traffic Control Plans in the
Contract are maximum spacings and may be reduced to meet actual field conditions as
required.
SECTION 9. GENERAL
9.a) If the required minimum number of signs and equipment (i.e. one High Mounted Internally
Illuminated Flashing Arrow for each lane closed, two TMAs, Changeable Message Sign,
etc.) are not available, the traffic control pattern shall not be installed.
9.b) The Contractor shall have back-up equipment (TMAs, High Mounted Internally
Illuminated Flashing Arrow, Changeable Message Sign, construction signs, cones/drums,
etc.) available at all times in case of mechanical failures, etc. The only exception to this is
in the case of sudden equipment breakdowns in which the pattern may be installed but the
Contractor must provide replacement equipment within 24 hours.
9.c) Failure of the Contractor to have the required minimum number of signs and equipment,
which results in the not being installed, shall not be a reason for a time extension.
9.d) In cases of legitimate differences of opinion between the Contractor and the Inspection
staff, the Inspection staff shall err on the side of safety. The matter shall be brought to the
District Office for resolution immediately or, in the case of work after regular business
hours, on the next business day.
