1. Receiving, reviewing, and approving all correspondence, submittals, and reports before they aresubmitted to the Department

2. Signing QC plans3. Implementing QC plans4. Maintaining QC records

The QC manager must be responsible directly to you for the quality of the work, including materials andworkmanship performed by you and your subcontractors.

The QC manager must be your employee or must be hired by a subcontractor providing only QCservices. The QC manager must not be employed or compensated by a subcontractor or by otherpersons or entities hired by subcontractors who will provide other services or materials for the project.

Notify the Engineer of the name and contact information of the QC manager.

11-2 PRECAST CONCRETE MEMBERS11-2.01 GENERALSection 11-2 applies to PC concrete members fabricated under sections 49 or 51 excluding PC concretemembers fabricated with minor concrete.

Fabricate PC concrete members at a plant on the Authorized Facility Audit List.

11-2.02 PRECAST CONCRETE QUALITY CONTROL MANAGERAssign a PC concrete QC manager for each precasting plant.

11-2.03 QUALITY CONTROL INSPECTORThe QC inspector must witness all PC concrete activities.

The QC inspector must either (1) be registered as a civil engineer in the State or (2) have a current PlantQuality Personnel Certification, Level II from the Precast/Prestressed Concrete Institute.

The QC inspector must perform inspection and testing before precasting, during precasting, and afterprecasting, as specified and as necessary to ensure that materials and workmanship comply with theContract.

Regardless of your acceptance of a PC concrete member, the Engineer inspects PC concrete membersand rejects any members that do not comply with the Contract.

11-2.04 SUBMITTALS11-2.04A GeneralBefore submitting the PC concrete QC plan, hold a meeting to discuss the requirements for PC concreteQC. The meeting attendees must include the Engineer, the PC concrete QC manager, and arepresentative from each plant performing PC concrete activities for the Contract.

When constructing an embankment against an existing slope or when constructing 1/2 the embankmentwidth at a time, prepare the slope by cutting into it at least 6 feet horizontally as you place the newembankment in layers. Compact the cut material along with the new embankment material.

For bridge footings to be constructed in embankment, construct the embankment to the grading planeelevation and extend the finished slope to the grading plane before:

1. Excavating for footings2. Driving piles or drilling holes for CIP piles

The grading plane of embankments beneath structure approach slabs and beneath the thickened portionof sleeper slabs must not project above the grade established by the Engineer.

Grade trenches, holes, depressions, and pits outside of areas where embankments are to be constructedto provide a presentable and well-drained area.

19-6.03B SubsidenceNot Used

19-6.03C Placing and CompactingDo not construct embankments when material is frozen or a blanket of snow prevents proper compaction.

Construct embankment in layers. The loose thickness of each layer must not exceed 8 inches.

Break up clods or hard lumps of earth that are over 8 inches in greatest dimension before compactingmaterial in the embankment, except if material, such as hardpan or cemented gravel, cannot be brokenreadily:

1. Distribute material throughout the embankment2. Place enough earth or other fine material around the larger material as you deposit it to fill the

interstices and produce a dense, compact embankment.

If embankment material contains the following percentages by volume of rock larger than 8 inches ingreatest dimension, before compaction, the loose thickness of each layer of embankment material belowa plane 3 feet below finished grade must comply with the following table:

Percent by volume Loose layer thicknessOver 50 Max. rock sizeFrom 25 to 50 Max. rock size up to 3 feetLess than 25 8 inches in areas between rocks

larger than 8 inches

Reinforcement or metal attached to reinforced concrete rubble placed in embankments must not protrudeabove the grading plane. Trim reinforcement or metal to less than 3/4 inch from the face of the reinforcedconcrete rubble material before placing the material within 2 feet below the grading plane.

In a sidehill embankment where the width, including bench cuts for bonding existing and newembankments, is too narrow to accommodate mobile power compacting equipment, you may place thematerial by end dumping, if authorized.

If end dumping is allowed for constructing embankment against existing slopes or 1/2 the embankmentwidth at a time, then plow or cut the slopes of the original ground or embankment before end dumpingstarts.

Where embankments are constructed across low, swampy ground that cannot support the weight ofhauling equipment, you may construct the lower part of the embankment by dumping successive loads ina uniformly distributed layer that can support equipment for placing subsequent layers.

Construct embankments such that each layer has a cross fall less than 5 percent.

Construct transverse contraction joints within 1 foot of their specified spacing. If a slab length of less than5 feet would be formed, adjust the transverse contraction joint spacing.

Construct transverse contraction joints across the full concrete pavement width regardless of the numberor types of longitudinal joints crossed. In areas of converging and diverging pavements, space transversecontraction joints so their alignment is continuous across the full width where converging and divergingpavements are contiguous. Longitudinal contraction joints must be parallel with the concrete pavementcenterline. Transverse and longitudinal contraction joints must not deviate by more than 0.1 foot fromeither side of a 12-foot straight line, except for longitudinal joints parallel to a curving centerline.

If widening existing concrete pavement, do not construct transverse contraction joints to match theexisting pavement's joint spacing or skew unless specified.

40-1.03E(4) Isolation JointsConstruct isolation joints by saw cutting a minimum 1/8-inch width to full concrete pavement depth at theexisting concrete pavement's edge. Remove the concrete to expose a flat vertical surface. Before placingconcrete, secure joint filler material that prevents new concrete from adhering to the existing concreteface.

40-1.03E(5) Sawing MethodSawing method consists of cutting a groove in the concrete pavement with a power driven concrete saw.Grooves for longitudinal and transverse contraction joints must be the minimum width possible for thetype of saw used. If necessary, the top of the joint must be sawn wider to provide space for joint sealant.Immediately wash slurry from the joint with water at 100 psi maximum pressure.

Saw longitudinal and transverse contraction joints before cracking occurs and after the concrete is hardenough to saw without spalling, raveling, or tearing.

To keep foreign material out of grooves before joint sealant or compression seal installation, you may usea filler in sawed contraction joints. Joint filler material must not react adversely with the concrete or causeconcrete pavement damage. After sawing and washing a joint, install joint filler material that keepsmoisture in the adjacent concrete during the 72 hours after paving. If you install joint filler material, thespecifications for spraying the sawed joint with additional curing compound in section 40-1.03N do notapply. If using absorptive filler material, moisten the filler immediately before or after installation.

40-1.03E(6) Joint Sealant and Compression Seal Installation40-1.03E(6)(a) GeneralDo not seal construction joints.

At least 7 days after concrete pavement placement and not more than 4 hours before installing jointsealant or compression seal materials, use dry sandblasting and other methods to clean the joint walls ofobjectionable material such as soil, asphalt, curing compound, paint, and rust. The maximumsandblasting nozzle diameter must be 1/4 inch. The minimum pressure must be 90 psi. Sandblast eachside of the joint at least once, in at least 2 separate passes. Hold the nozzle at an angle to the joint from 1to 2 inches from the concrete pavement. Using a vacuum, collect sand, dust, and loose material at least 2inches on each side of the joint. Remove surface moisture and dampness at the joints with compressedair that may be moderately hot.

Before you install joint sealant or compression seal, the joint wall must be free of moisture, residue, orfilm.

If grinding or grooving over or adjacent to sealed joints, remove and dispose of joint sealant orcompression seal materials. After grinding or grooving, replace the joint sealant or compression sealmaterials.

40-1.03E(6)(b) Liquid SealantInstall backer rods when the concrete pavement temperature is above the air dew point and when the airtemperature is at least 40 degrees F.

Install liquid sealant immediately after installing the backer rod. Install sealant using a mechanical devicewith a nozzle shaped to introduce the sealant from inside the joint. Extrude sealant evenly and withcontinuous contact with the joint walls. Recess the sealant surface after placement. Remove excesssealant from the concrete pavement surface.

Do not allow traffic over sealed joints until the sealant is set.

40-1.03E(6)(c) Preformed Compression SealInstall preformed compressions seals in isolation joints when specified.

Install longitudinal seals before transverse seals. Longitudinal seals must be continuous except atintersections with transverse seals. Install transverse seals in 1 continuous piece for the entire transverselength of concrete pavement. With a sharp instrument, cut across the longitudinal seal at the intersectionwith transverse construction joints. If the longitudinal seal does not relax enough to properly install thetransverse seal, trim the longitudinal seal to form a tight seal between the 2 joints.

Use a machine specifically designed for preformed compression seal installation. The machine mustinstall the seal:

1. To the specified depth2. To make continuous contact with the joint walls3. Without cutting, nicking, or twisting the seal4. With less than 4 percent stretch

Lay a length of preformed compression seal material cut to the exact length of the pavement joint to besealed. The Engineer measures this length. After you install the length of preformed compression jointsealant, the Engineer measures the excess amount of material at the joint end. The Engineer divides theexcess amount length by the original measured length to determine the percentage of stretch.

40-1.03F Drilled CoresDrill concrete pavement cores under ASTM C 42/C 42M. Core drilling equipment must use diamondimpregnated bits.

Clean, dry, and fill core holes with hydraulic cement grout (non-shrink) or pavement concrete. Coat thecore hole walls with epoxy adhesive for bonding new concrete to old concrete under section 95. Thebackfill must match the adjacent concrete pavement surface elevation and texture.

40-1.03G Test StripsSection 40-1.03G applies to projects with more than 2,000 cubic yards of JPCP or CRCP.

The first paving activity must be to construct a test strip:

1. 700 to 1,000 feet long2. Same width as the planned paving3. With the same equipment used for the planned paving

The Engineer evaluates the test strip for compliance with the specifications for acceptance criteria.

The Engineer selects from 6 to 12 core locations for dowel bars and up to 6 locations for tie bars per teststrip.

If you use mechanical dowel bar inserters, the test strip must demonstrate they do not leave voids,segregations, or surface irregularities such as depressions, dips, or high areas.

Allow the Engineer 3 business days to evaluate the test strip for:

1. Smoothness2. Dowel bar and tie bar alignment3. Thickness4. Final finishing except coefficient of friction

During the 3 business day evaluation, the Engineer rejects a test strip if any of the following occurs:

1. Surface varies more than 0.02 foot from a 12-foot straightedge's lower edge2. Wheel path's individual high points are greater than 0.025 foot in 25 feet3. Dowel bars do not comply with specified placement tolerances4. Concrete pavement thickness deficiency is greater than 0.05 foot5. Final finishing does not comply with the specifications except coefficient of friction

Remove the test strip if the Engineer rejects it for noncompliance with the specifications for dowel baralignment, or thickness. Dispose of rejected test strip material.

If the Engineer rejects the test strip for noncompliance with the smoothness or final finishingspecifications except coefficient of friction, you may grind the test strip into compliance if you intend toleave it as part of the paving.

If the Engineer does not reject the test strip during the 3-business-day evaluation, you may beginproduction paving while the Engineer continues to evaluate the test strip for compliance with the otherspecifications. If the Engineer rejects the test strip for noncompliance with the other specifications, stopproduction paving until you construct a test strip the Engineer accepts.

For rejected test strips, submit a plan for changed materials, methods, or equipment before constructingadditional test strips. Construct additional test strips until the Engineer accepts one.

Construct additional test strips if you:

1. Propose different paving equipment including:1.1. Batch plant1.2. Paver1.3. Dowel bar inserter1.4. Tie bar inserter1.5. Tining1.6. Curing equipment

2. Change concrete mix proportions

The Engineer may authorize paving to start without a test strip if you use a batch plant mixer, pavingequipment, and personnel that completed a Department project of the same type within the preceding 12months. Submit supporting documents and previous project information.

40-1.03H Placing Concrete40-1.03H(1) GeneralPlace concrete pavement with stationary side forms or slip-form paving equipment.

Place consecutive concrete loads within 30 minutes of each other. Construct a transverse constructionjoint when concrete placement is interrupted by more than 30 minutes. The transverse construction jointmust coincide with the next contraction joint location, or you must remove fresh concrete pavement to thepreceding transverse joint location.

Place concrete pavement in full slab widths separated by construction joints or monolithically in multiplesof full lane widths with a longitudinal contraction joint at each traffic lane line.

Do not retemper concrete.

If the concrete pavement surface width is constructed as specified, you may construct concrete pavementsides on a batter not flatter than 6:1 (vertical:horizontal).

40-1.03H(3) Concrete Pavement Transition PanelFor concrete pavement placed in a transition panel, texture the surface with a drag strip of burlap, abroom, or a spring steel tine device that produces scoring in the finished surface. The scoring must beeither parallel with or transverse to the centerline. For the method you choose, texture at the time thatproduces the coarsest texture.

40-1.03H(4) Stationary Side Form ConstructionStationary side forms must be straight and without defects including warps, bends, and indentations. Sideforms must be metal except at end closures and transverse construction joints where other materials maybe used.

You may build up side forms by attaching a section to the top or bottom. If attached to the top of metalforms, the attached section must be metal.

The side form's base width must be at least 80 percent of the specified concrete pavement thickness.

Side forms including interlocking connections with adjoining forms must be rigid enough to preventspringing from subgrading and paving equipment and concrete pressure.

Construct subgrade to final grade before placing side forms. Side forms must bear fully on the foundationthroughout their length and base width. Place side forms to the specified grade and alignment of thefinished concrete pavement's edge. Support side forms during concrete placing, compacting, andfinishing.

After subgrade work is complete and immediately before placing concrete, true side forms and set to lineand grade for a distance that avoids delays due to form adjustment.

Clean and oil side forms before each use.

Side forms must remain in place for at least 1 day after placing concrete and until the concrete pavementedge no longer requires protection from the forms.

Spread, screed, shape, and consolidate concrete with 1 or more machines. The machines must uniformlydistribute and consolidate the concrete. The machines must operate to place the concrete pavement tothe specified cross section with minimal hand work.

Consolidate the concrete without segregation. If vibrators are used:

1. The vibration rate must be at least 3,500 cycles per minute for surface vibrators and 5,000 cycles perminute for internal vibrators

2. Amplitude of vibration must cause perceptible concrete surface movement at least 1 foot from thevibrating element

The Department performs acceptance testing using gamma-gamma logging to test the concrete densityof the pile for homogeneity.

After notification by the Engineer of pile acceptance, dewater the inspection pipes and cored holes and fillthem with grout. Grout must comply section 50-1.02C. Fill inspection pipes and holes using grout tubesthat extend to the bottom of the pipe or hole or into the grout already placed.

49-3.02A(4)(d)(ii) Vertical Inspection PipesInstall vertical inspection pipes for acceptance testing as follows:

1. Inspection pipes must be schedule 40 PVC pipe complying with ASTM D 1785 with a nominal pipesize of 2 inches. Watertight PVC couplers complying with ASTM D 2466 are allowed to facilitate pipelengths in excess of those commercially available. Log the location of the inspection pipe couplerswith respect to the plane of pile cutoff.

2. Cap each inspection pipe at the bottom. Extend the pipe from 3 feet above the pile cutoff to thebottom of the reinforcing cage. Provide a temporary top cap or similar means to keep the pipes cleanbefore testing. If pile cutoff is below the ground surface or working platform, extend inspection pipesto 3 feet above the ground surface or working platform.

3. If any changes are made to the pile tip, extend the inspection pipes to the bottom of the reinforcingcage.

4. Install inspection pipes in a straight alignment, parallel to the main reinforcement, and securelyfastened in place to prevent misalignment during installation of the reinforcement and placing ofconcrete in the hole. Construct CIDH concrete piles such that the relative distance of inspection pipesto vertical steel reinforcement remains constant.

5. Fill inspection pipes with water upon completion of the concrete placement to prevent debonding ofthe pipe.

6. Inspection pipes must be completely clean, dry, and unobstructed at the time of testing providing a 2-inch diameter clear opening.

7. Provide safe access to the tops of the tubes.

After placing concrete and before requesting acceptance testing, test each inspection pipe in thepresence of the Engineer by passing a 1-1/4-inch-diameter by 4.5-foot-long rigid cylinder through thelength of pipe.

If an inspection pipe fails to pass the rigid cylinder:

1. Immediately fill all inspection pipes in the pile with water2. Core a nominal 2-inch diameter hole through the concrete for the entire length of the pile for each

inspection pipe that does not pass the rigid cylinder3. Locate cored holes as close as possible to the inspection pipes they are replacing and no more than

5 inches clear from the reinforcement

Coring must not damage the pile reinforcement. Core holes using a double wall core barrel system with asplit tube type inner barrel. Coring with a solid type inner barrel is not allowed. Coring methods andequipment must provide intact cores for the entire length of the pile. Preserve cores and identify themwith the exact location the core was recovered from the pile.

The coring activity must be logged by an engineering geologist or civil engineer licensed in the State andexperienced in core logging. Coring logs must comply with Caltrans' Soil and Rock Logging,Classification, and Presentation Manual. Coring logs must include core recovery, rock quality designation,locations of breaks, and complete descriptions of inclusions and voids encountered during coring.

The Department evaluates the portion of the pile represented by the cored hole based on the submittedcore logs. If the Department determines that a pile is anomalous based on the coring logs, the pile isrejected.

If inspection pipes are not shown:

1. Include in the pile installation plan a plan view drawing of the pile showing reinforcement andinspection pipes.

2. Place inspection pipes radially around the pile, inside the outermost spiral or hoop reinforcement andno more than 1 inch clear of the outermost spiral or hoop reinforcement.

3. Place inspection pipes around the pile at a uniform spacing not exceeding 33 inches measured alongthe circle passing through the centers of inspection pipes. Use at least 2 inspection pipes per pile.Place inspection pipes to provide the maximum diameter circle that passes through the centers of theinspection pipes while maintaining the spacing required herein.

4. Place inspection pipes at least 3 inches clear of the vertical reinforcement. Where the verticalreinforcement configuration does not allow this clearance while achieving radial locationrequirements, maximize the distance to vertical rebar while still maintaining the requirement for radiallocation.

Where the dimensions of the pile reinforcement do not allow inspection pipes to be placed as specifiedabove, submit a request for deviation before fabricating pile reinforcement.

49-3.02A(4)(d)(iii) Gamma-Gamma LoggingThe Department performs gamma-gamma logging under California Test 233.

Separate reinforcing steel as necessary to allow the Department access to the inspection pipes.

After requesting testing and providing access to the piles, allow 15 days for the Department to performthe testing and to prepare and provide the pile acceptance test report.

During testing, do not perform construction activities within 25 feet of any gamma-gamma logging activity.

If the Department determines that a pile is anomalous under California Test 233, part 5C, the pile isrejected.

49-3.02A(4)(d)(iv) Rejected PilesIf a pile is rejected:

1. Suspend concrete placement in the remaining piles2. Revise the pile installation plan and submit it to the Engineer3. Do not resume concrete placement until the revised pile installation plan is authorized

Allow 30 days for the Department to determine whether the rejected pile requires mitigation and toprovide this information to you. Day 1 of the 30 days is the 1st day after access has been provided to theDepartment to perform acceptance testing.

The Department may perform additional tests to further evaluate a rejected pile. These tests may includecrosshole sonic logging and other means of inspection selected by the Department. The pile acceptancetest report will indicate if the Department intends to perform any additional testing and when the testing

Placing concrete must be a continuous activity lasting no longer than the time specified for each concreteplacing activity at each pile in your pile installation plan.

The delivery tube system must consist of one of the following:

1. A tremie tube or tubes, each of which is at least 10 inches in diameter, fed by one or more concretepumps

2. One or more concrete pump discharge tubes, each fed by a single concrete pump

The delivery tube system must consist of watertight tubes with sufficient rigidity to keep the tube endsalways in the mass of concrete placed. If only 1 delivery tube is used to place the concrete, place the tubenear the center of the hole. Multiple tubes must be uniformly spaced in the hole.

Internal bracing for the steel reinforcing cage must accommodate the delivery tube system. Do not usetremies for piles without space for a 10-inch-diameter tube.

During concrete placement, provide a fully operational standby concrete pump at the job site that isadequate to complete the work in the time specified in the pile installation plan.

Do not allow concrete to fall into the slurry during concrete placing activities. Cap the delivery tube with awatertight cap, or plug the tube above the slurry level with a good quality, tight fitting, moving plug that willexpel the slurry from the tube as the tube is charged with concrete. The cap or plug must be designed torelease as the tube is charged.

Extend the pump discharge or tremie tube to the bottom of the hole before charging the tube withconcrete. After charging the tube with concrete, induce the flow of concrete through the tube by slightlyraising the discharge end.

During concrete placement:

1. Embed the tip of the delivery tube within 6 inches of the bottom of the hole until 10 feet of concretehas been placed. Maintain the embedment of the tip at least 10 feet below the top surface of theconcrete

2. Do not rapidly raise or lower the delivery tube3. Maintain the slurry level 10 feet above the piezometric head or within 12 inches of the top of the

drilled hole, whichever is higher

If the seal is lost or the delivery tube becomes plugged and must be removed:

1. Withdraw and clean the tube.2. Cap the tip of the tube to prevent slurry from entering.3. Restart the operation by pushing the capped tube 10 feet into the concrete and then reinitiating the

flow of concrete.

Maintain a log of concrete placement for each drilled hole. The log must:

1. Show the pile location, tip elevation, dates of excavation and concrete placement, total quantity ofconcrete placed, length and tip elevation of any casing, and details of any hole stabilization methodand materials used.

2. Include an 8-1/2 by 11 inch graph of concrete placed versus depth of hole filled as follows:2.1 Label the graph with the pile location, tip elevation, cutoff elevation, and the dates of

excavation and concrete placement.2.2 Plot the graph continuously throughout concrete placement. Plot the depth of drilled hole filled

vertically with the pile tip at the bottom and the quantity of concrete placed horizontally.2.3 Take readings at each 5 feet of pile depth, and indicate the time of the reading on the graph.

If a temporary casing is used, maintain concrete placed under slurry at a level at least 5 feet above thebottom of the casing. The withdrawal of the casing must not cause contamination of the concrete withslurry.

Ducts must be clean and free from water and deleterious materials that would impair bonding of the groutor interfere with grouting procedures.

Grout must pass through a screen with 0.07-inch maximum clear openings before being introduced intothe grout pump.

Prevent the leakage of grout through the anchorage assembly by positive mechanical means.

Pump grout through the duct as follows:

1. Continuously waste grout at the outlet until no visible slugs or other evidence of water or air is ejectedand the efflux time of ejected grout is at least 11 seconds

2. Close the outlet valve and hold the pumping pressure momentarily3. Close the valve at the inlet while maintaining the pressure

If hot weather conditions will contribute to quick stiffening of the grout, cool the grout by authorizedmethods as necessary to prevent blockages during pumping activities.

If freezing weather conditions are anticipated during and following the placement of grout, provideadequate means to protect the grout in the ducts from damage by freezing.

After completing duct grouting activities:

1. Abrasive blast clean and expose the aggregate of concrete surfaces where concrete is to be placedto cover and encase the anchorage assemblies

2. Remove the ends of vents 1 inch below the roadway surface

50-1.03B(2)(d)(ii) Grouting EquipmentGrouting equipment must be:

1. Capable of grouting at a pressure of at least 100 psi2. Equipped with a pressure gage having a full-scale reading of not more than 300 psi

If requested, check individually-tensioned strands for loss of prestress not more than 48 hours beforeplacing concrete for the members, using authorized methods and equipment. Strands showing a loss ofprestress of more than 3 percent must be retensioned to the original computed jacking force.

If prestressing steel in pretensioned members is tensioned at a temperature appreciably lower than theestimated temperature of the concrete and the prestressing steel at the time of initial set of the concrete,the calculated elongation of the prestressing steel must be increased to compensate for the loss in stress.

The maximum temporary tensile stress in the prestressing steel of pretensioned members must notexceed 80 percent of the specified minimum ultimate tensile strength of the prestressing steel.

Perform the cutting and releasing of prestressing steel in pretensioned members in such an order thatlateral eccentricity of prestress is a minimum.

Anchor the prestressing steel at stresses that will result in the ultimate retention of jacking forces at leastequal to those shown.

Cut off pretensioned prestressing steel flush with the end of the member. After cutting the steel, clean andpaint the exposed ends of the steel and a 1-inch strip of adjoining concrete as follows:

1. Wire brush or abrasive blast clean to remove all dirt and residue on the metal and concrete surfaces.2. Immediately after cleaning, apply 1 application of organic zinc-rich primer to the surfaces, except

apply 2 applications to surfaces that will not be covered by concrete or mortar. Do not use aerosolcans. Mix the paint thoroughly when applying and work into any voids in the prestressing steel.

Except for CIP piles, do not allow fresh concrete to fall more than 8 feet without using pipes, tubes, ordouble belting to prevent segregation. Do not use double belting unless the member thickness is lessthan 16 inches.

Consolidate concrete using high-frequency vibrators within 15 minutes of placement. Do not use vibratorsfor pipe culvert headwalls and endwalls, slope paving and aprons, and concrete placed under water. Donot attach vibrators to or hold them against forms or reinforcing steel. Do not displace reinforcement,ducts, or prestressing steel during vibrating.

For structure footings over 2.5 feet in depth that have a top layer of reinforcement, reconsolidate theconcrete to a depth of 1 foot after placing, consolidating, and initial screeding of the concrete.Reconsolidate the concrete as late as the concrete will respond again to vibration but not less than 15minutes after the initial screeding.

Vibrators used for concrete with epoxy-coated reinforcement or prestressing steel must have a resilientcovering to prevent damage to the epoxy coating.

You may use external vibrators only if consolidation by other means is not possible. Forms must besufficiently rigid to resist displacement or damage. The use of external vibrators must be authorized.

Do not place concrete for horizontal members until the concrete in supporting vertical members has beenconsolidated and settlement due to bleeding is complete.

Where shown, apply a bond breaker to joint surfaces.

Do not construct drainage structures to final grade until adjacent paving or surfacing is complete.

51-1.03D(2) Concrete Bridge DecksFor concrete decks placed on continuous steel girders or PC concrete girders, place the portion of deckover the supports last.

For decks on PC concrete girders, place intermediate and end diaphragms at least 5 days before placingthe deck concrete.

For decks on structural steel, install cross frames the entire width of the bridge before placing the deckconcrete.

Deck closure pours must comply with the following:

1. During primary deck placement and for at least 24 hours after completing the deck placement,reinforcing steel protruding into the closure space must be free from any connection to reinforcingsteel, concrete, forms, or other attachments of the adjacent structure.

Concrete must be of a consistency such that after extrusion or slip forming it will maintain the shape ofthe barrier without support.

The grade for the top of the concrete barrier must be indicated by an offset guide line set from surveymarks established by the Engineer. The forming portion of the extrusion or slip form machine must bereadily adjustable vertically during the forward motion of the machine to conform to the predeterminedgrade line. A grade line gage or pointer must be attached to the machine such that a continualcomparison can be made between the barrier being placed and the established grade line as indicated bythe offset guide line.

Instead of the above method for maintaining the barrier grade, the extrusion or slip form machine may beoperated on rails or forms set at uniform depth below the predetermined finished top of the barrier gradeor on existing pavement or bridge decks.

You may construct expansion joints by sawing through the barrier section to its full depth. Insertion of jointfiller is not required.

If expansion joints are not constructed by sawing, construct the expansion joints under section 51.

If sawing or forming the joints is performed before the concrete has hardened, firmly support the adjacentportions of the barrier with close fitting shields.

If sawing or forming the joints is performed after the application of curing compound, treat the exposedfaces of the barrier in the vicinity of the joint with curing compound after sawing or forming the joints.

If extrusion or slip forming methods of placement are used, the horizontal reinforcing bars must be placedcontinuously.

83-2.02D(4) FinishingThe surface finish of Type 50 and Type 60 series concrete barriers, before the application of the curingcompound, must be free from surface pits larger than 1 inch in diameter and must be given a final softbrush finish with strokes parallel to the line of the barriers. Finishing with a brush application of grout isnot allowed.

To facilitate finishing, remove fixed forms for CIP Type 50 and Type 60 series concrete barriers as soonas possible after the concrete has set enough to maintain the shape of the barrier without support.

Not less than 7 days after placing Type 50 and Type 60 series concrete barriers, exposed surfaces mustreceive a light abrasive blast finish to achieve a uniform appearance.

The final surface finish of concrete barriers other than Type 50 and Type 60 series must be Class 1surface finish under section 51-1.03F(3). Alternative final surface finish methods must be submitted inwriting and must not be used unless authorized.

90-1.01D(4) Concrete UniformityThe Engineer determines the uniformity of concrete mixtures based on differences in test results between2 test samples of mixed concrete from the same batch for the following tests:

1. California Test 533 if the mix design specifies a penetration value2. ASTM C 143 if the mix design specifies a slump value3. California Test 529

90-1.01D(5) Compressive Strength90-1.01D(5)(a) GeneralSection 90-1.01D(5) applies for either of the following cases:

1. Concrete is designated by compressive strength.2. Attaining a minimum concrete compressive strength is specified as a prerequisite to applying loads or

stresses to a concrete structure or member.

If the 28-day compressive strength described is 3,600 psi or greater, the concrete is designated bycompressive strength.

If the concrete is designated by compressive strength, the strength of concrete that is not steam cured isdetermined from cylinders cured under Method 1 of California Test 540.

If attaining a minimum concrete compressive strength is specified as a prerequisite to applying loads orstresses to a concrete structure or member, cylinders for concrete that is not steam cured are curedunder Method 1 of California Test 540 and the concrete compressive strength is evaluated based onindividual tests.

For concrete with a described 28-day compressive strength greater than 3,600 psi, 42 days are allowedto attain the strength described.

Except for concrete specified to be in a freeze-thaw area, 56 days are allowed to attain the strengthdescribed if the cementitious material satisfies the following equation:

[(41 x UF) + (19 x F) + (11 x SL)]/TC 7.0

F = natural pozzolan or fly ash complying with AASHTO M 295, Class F or N, including the quantity inblended cement, lb/cu yd. F is equivalent to the sum of FA and FB as defined in section 90-1.02B(3).

SL = GGBFS, including the quantity in blended cement, lb/cu ydUF = silica fume, metakaolin, or UFFA, including the quantity in blended cement, lb/cu ydTC = total quantity of cementitious material used, lb/cu yd

For concrete satisfying the equation above, test for the compressive strength at least once every 500 cuyd at 28, 42, and 56 days. Submit the test results to the Engineer.

The Engineer determines the concrete compressive strength from test cylinders:

1. Made from concrete sampled under California Test 5392. Molded and initially field cured under California Test 5403. Cured and tested under California Test 521

A compressive strength test represents no more than 300 cu yd of concrete and consists of the averagecompressive strength of 2 cylinders made from material taken from a single load of concrete. If a cylindershows evidence of improper sampling, molding, or testing, the cylinder is discarded and the test consistsof the compressive strength of the remaining cylinder.

If a single compressive strength test result is below the strength described at the maximum age specifiedor allowed, or if the compressive strength of concrete tested at 7 days indicates to the Engineer that theconcrete will not attain the strength described at the maximum age specified or allowed, correct the mixdesign or concrete fabrication procedures and obtain authorization before you place additional concrete.

If the compressive strength is below 85 percent of the strength described, you must remove the concrete.

If a strength test result at the maximum age specified or allowed is below 85 percent of the strengthdescribed, you must remove the concrete represented by the test unless you obtain and submit evidencethat the strength of the concrete placed in the work is at least 85 percent of the strength described andthis evidence is accepted by the Engineer.

If the evidence consists of tests made on cores taken from the work, obtain and test the cores underASTM C 42.

90-1.01D(5)(b) PrequalificationIf the concrete has a described 28-day compressive strength greater than 3,600 psi, or if prequalificationis specified, prequalify the materials, mix proportions, mixing equipment, and procedures proposed foruse in the work before placing the concrete.

Submit certified test data or trial batch test reports based on the same materials, mix proportions, mixingequipment, procedures, and batch size proposed for use in the work.

Certified test data must show that:

1. Results of 90 percent or more of at least 20 consecutive tests exceed the compressive strengthdescribed at the maximum number of days specified or allowed and none of the test results are lessthan 95 percent of the strength described

2. All tests are the most recent tests made on concrete of the proposed mix design and were madewithin 1 year of the proposed use of the concrete

Trial batch test reports must show that:

1. Average compressive strength for 5 consecutive concrete cylinders taken from a single batch andtested at not more than the maximum age specified or allowed is at least 600 psi greater than the 28-day compressive strength described

2. No individual cylinder has a strength less than the strength described at the maximum age specifiedor allowed

Store and dispense the admixtures in liquid form.

Admixture properties must be uniform throughout their use in the work.

If more than 1 admixture is used, the admixtures must be compatible with each other such that thedesirable effects of all the admixtures used are realized.

Use chemical admixtures in compliance with the manufacturer's written instructions. The instructions mustinclude a statement that the admixture is compatible with the types and quantities of SCM used.

90-1.02E(2) Chemical AdmixturesIf the use of chemical admixtures is specified, use the dosage specified. If the dosage is not specified,use the dosage recommended by the admixture manufacturer.

You may use any of the following admixture types to conserve cementitious material or to facilitateconstruction:

1. Type A or F, water-reducing2. Type B, retarding3. Type D or G, water-reducing and retarding

If you use a water-reducing admixture or a water-reducing and retarding admixture, you may reduce thespecified cementitious material content by up to 5 percent by weight. The resulting concrete must containat least 505 pounds of cementitious material per cubic yard. If you reduce the cementitious materialcontent, use at least the admixture dosage used in authorizing the admixture as shown on the AuthorizedMaterial List.

90-1.02F(2) Storage of AggregatesStore or stockpile aggregates such that the coarse and fine particles of each size do not separate andvarious sizes do not intermix before proportioning.

Prevent contamination by foreign materials while storing, stockpiling, and handling aggregates.

If you store the aggregates at a batching or mixing plant that is erected after the Contract is awarded andis used for furnishing concrete for the work:

1. Prevent intermingling of different aggregate sizes by using measures such as the physical separationof stockpiles or the construction of bulkheads of adequate length and height

2. Prevent contamination of the aggregates by contact with the ground through measures such asplacing the aggregates on wooden platforms or on hardened surfaces made of concrete, asphaltconcrete, or cement-treated material

When placing the aggregates in storage or moving the aggregates from storage to the weigh hopper ofthe batching plant, do not use methods that cause:

1. Segregation, degradation, or the combining of materials of different gradings and result in anaggregate size failing to comply with the grading specifications at the weigh hopper

2. Excessive particle breakage

You may be required to use devices that reduce the impact of falling aggregates.

90-1.02F(3) Proportioning DevicesAutomatic weighing systems must comply with section 90-1.02F(4)(c). For an automatic device, the singleoperation of a switch or starter must be the only manual operation required to proportion the aggregates,cement, and SCM for 1 batch of concrete.

Insulate the weighing equipment against the vibration or movement of other plant equipment.

The weight of each batch of material must not vary from the weight designated by the Engineer by morethan the specified tolerances.

The weighing and measuring equipment must have the following zero tolerances:

1. For cumulative weighing of aggregates, ±0.5 percent of the designated total aggregate batch weight2. For weighing each aggregate size separately, ±0.5 percent of the designated batch weight for each

aggregate size3. For cumulative weighing of cement and SCM, ±0.5 percent of the designated total batch weight of the

cement and SCM4. For weighing cement and SCM separately, ±0.5 percent of their designated individual batch weights5. For measuring water, ±0.5 percent of its designated weight or volume

The weight indicated for a batch of material must not vary from the preselected scale setting by more thanthe following:

1. Aggregates weighed cumulatively must be within ±1.0 percent of the designated total aggregatebatch weight.

2. Aggregates weighed separately must be within ±1.5 percent of the designated batch weight of eachaggregate.

3. Cement weighed separately must be within +2 to -1 percent of the designated cement batch weight.4. SCM weighed separately must be within +2 to -1 percent of the designated SCM batch weight.5. For cement and SCM weighed cumulatively, the cement must be within +2 to -1 percent of the

designated cement batch weight and the total for cement and SCM must be within +2 to -1 percent ofthe sum of the designated cement and SCM batch weights.

6. Water must be within ±1.5 percent of the designated weight or volume of water.

STRUCTURES (BRIDGES, MSE WALLS & I-10 RCB SLAB) 03315-DB - 231

Each scale graduation must be no more than 0.001 of the total scale capacity. For each material beingweighed, use a scale with single graduations that indicate a weight not exceeding the maximumpermissible weight variation above, except that graduations less than 1 lb are not required.

90-1.02F(4) Proportioning90-1.02F(4)(a) GeneralProportioning consists of dividing the aggregates into the specified sizes, each stored in a separate bin,and combining the aggregates with cementitious material, admixtures if used, and water.

Proportion the aggregates by weight.

At the time of batching:

1. Aggregates must be dried and drained to a stable moisture content such that no visible separation ofwater from the aggregate occurs during transportation from the proportioning plant to the point ofmixing

2. Free moisture content of the fine aggregate must not exceed 8 percent of its saturated surface-dryweight

If the proportioning plant has separate supplies of the same size group of aggregate with differentmoisture content, specific gravity, or surface characteristics affecting workability, exhaust one supplybefore using another supply.

Weigh bulk Type IP (MS) or Type IS (MS) cement in an individual hopper and keep it separate from theaggregates until the ingredients are released for discharge into the mixer.

Bulk cement and SCM may be weighed in separate weigh hoppers or in the same weigh hopper. Keepthe cement and SCM separate from the aggregates until the ingredients are released for discharge intothe mixer.

If the cement and SCM are weighed in the same weigh hopper, weigh the cement first. If the cement andSCM are weighed in separate weigh hoppers, the weigh systems for the proportioning of the aggregate,the cement, and the SCM must be individual and distinct from all other weigh systems. To constitute anindividual and distinct material-weighing device, each weigh system must have a hopper, a lever system,and an indicator.

Discharge the cement and the SCM into the mixer simultaneously with the aggregate.

The scales and weigh hoppers for bulk weighing cement, SCM, or cement plus SCM must be separateand distinct from the aggregate weighing equipment.

For batches of 1 cu yd or more, the batching equipment must comply with one of the followingcombinations:

1. Separate boxes and separate scale and indicator for weighing each aggregate size2. Single box and scale indicator for all aggregates3. Single box or separate boxes and automatic weighing mechanism for all aggregates

If you are requested to check the accuracy of batch weights, determine the gross weight and tare weightof batch trucks, truck mixers, truck agitators, and nonagitating hauling equipment. Weigh the equipmentusing scales designated by the Engineer.

For proportioning pavement concrete, install and maintain in good operating condition an electronicallyactuated moisture meter that indicates, on a readily visible scale, changes in the moisture content of thefine aggregate as it is batched within a sensitivity of 0.5 percent by weight of the fine aggregate.

90-1.02F(4)(b) Proportioning and Dispensing Liquid AdmixturesLiquid admixture dispensers must:

STRUCTURES (BRIDGES, MSE WALLS & I-10 RCB SLAB) 03315-DB - 232

1. Have enough capacity to measure at 1 time the total quantity of admixture required for each batch ofconcrete

2. Include a graduated measuring unit that is accurate to within ±5 percent of the required quantity foreach batch of concrete

3. Be located and maintained such that the graduations can be read accurately from the point at whichproportioning is controlled to allow a visual check of batching accuracy before discharge

4. Have measuring units that are clearly marked for the type and quantity of admixture

Each liquid admixture dispensing system must be equipped with a sampling device that consists of avalve located in a safe and readily accessible position such that the Engineer can slowly withdraw a testsample.

If more than 1 liquid admixture is used in the concrete mix, each admixture must have a separatemeasuring unit and must be dispensed by injecting equipment located such that the admixtures are notmixed at high concentrations and do not interfere with the effectiveness of each other.

If an air-entraining admixture is used with other liquid admixtures, incorporate the air-entraining admixtureinto the mix first, unless you demonstrate that a different sequence improves performance.

If automatic proportioning devices are used, the liquid admixture dispensers must operate automaticallywith the batching control equipment. The dispensers must have an automatic warning system in goodoperating condition that provides a visible or audible signal at the point at which proportioning iscontrolled. The signal must activate if the quantity of admixture measured varies from the preselecteddosage by more than 5 percent or if the entire contents of the measuring unit are not emptied from thedispenser.

Add liquid admixtures to the premeasured batch water or discharge the admixtures into the stream ofwater such that they are well-dispersed throughout the batch.

You may dispense air-entraining admixtures directly into moist sand in the batching bins if you maintainadequate control of the concrete air content.

90-1.02F(4)(c) Automatic ProportioningAutomatic proportioning devices must be authorized by the Department.

The batching of the aggregate and the cement, SCM, or cement plus SCM must be interlocked such thata new batch cannot start until all weigh hoppers are empty, the proportioning devices are within zerotolerance, and the discharge gates are closed.

The interlock must not allow any part of the batch to be discharged until all aggregate hoppers and thecement and SCM hoppers or the cement plus SCM hopper are charged with weights that are within thetolerances specified in section 90-1.02F(3).

If interlocks are required for the cement and SCM charging mechanisms and the cement and SCM areweighed cumulatively, their charging mechanisms must be interlocked to prevent the introduction of SCMuntil the weight of cement in the cement weigh hopper is within the tolerances specified in section 90-1.02F(3).

If the concrete is mixed completely in a stationary mixer, weigh the SCM in a separate weigh hopper andintroduce the SCM and cement simultaneously into the mixer proportionately with the aggregate. If yousubmit certification that the stationary mixer is capable of mixing the cement, SCM, aggregates, and wateruniformly before discharge, you may weigh the SCM cumulatively with the cement. Certification mustinclude:

1. Test results for 2 compressive strength test cylinders taken within the first 1/3, and 2 compressivestrength test cylinders taken within the last 1/3, of a single batch of concrete discharged from thestationary mixer. Strength tests and cylinder preparation must comply with section 90-1.01D(5).

2. Calculations demonstrating that the average of the 2 compressive strengths taken within the first 1/3of the batch do not differ by more than 7.5 percent from the average of the 2 compressive strengthstaken within the last 1/3 of the batch.

3. Mixer rotation speed and time of mixing before discharge that are required to produce a mix thatcomplies with the above requirements.

The discharge gate on the cement and SCM hoppers or the cement plus SCM hopper must be designedto allow the regulation of the flow of cement, SCM, or cement plus SCM into the aggregate.

If separate weigh boxes are used for each aggregate size, the discharge gates must allow the regulationof the flow of each aggregate size.

Material discharged from each bin must be controlled by gates or by mechanical conveyors.

The means of withdrawl from the bins and of discharge from the weigh box must be interlocked such thatnot more than 1 bin can discharge at a time and the weigh box cannot be tripped until the requiredquantity from each bin has been deposited into it.

If a separate weigh box is used for each aggregate size, all the weigh boxes may be operated anddischarged simultaneously.

If the discharge from the bins is controlled by gates, each gate must be actuated automatically such thatthe required weight is discharged into the weigh box, after which the gate must automatically close andlock.

The automatic weighing system must be designed to allow all required proportions to be set on theweighing controller at the same time.

90-1.02G Mixing and Transporting Concrete90-1.02G(1) GeneralMix the concrete in a mechanically operated mixer, except, if allowed by the Engineer, you may mixbatches not exceeding 1/3 cu yd by hand methods under section 90-1.02G(5).

Do not use equipment with components made of aluminum or magnesium alloys that could have contactwith plastic concrete during mixing, transporting, or pumping.

Concrete must be thoroughly mixed, homogeneous, and free of lumps or evidence of undispersedcementitious material.

90-1.02G(2) Machine MixingConcrete mixers must be the revolving drum or revolving blade type. Operate the mixing drum or bladesuniformly at the mixing speed recommended by the manufacturer. Do not use a mixer or agitator that hasan accumulation of hard concrete or mortar.

Immediately before placing the concrete, the temperature of the mixed concrete must be from 50 to 90degrees F. Cool or heat the aggregates and mixing water as necessary to produce concrete within thesetemperature limits. Do not heat the aggregates or water above 150 degrees F. Any ice used to cool theconcrete must be melted before the concrete is discharged from the mixer.

Charge the batch into the mixer such that some water enters before the cementitious materials andaggregates. Add all the water to the drum by the end of the first 1/4 of the specified mixing time. If theconcrete is delivered in a truck mixer, you may withhold a portion of the mixing water and, if allowed bythe Engineer, add it at the delivery point as specified in section 90-1.02G(3).

Batch and charge the cementitious materials into the mixer by means that will not cause:

1. Loss of cementitious materials due to the effect of wind2. Accumulation of cementitious materials on the surfaces of conveyors or hoppers3. Other conditions that reduce or vary the required quantity of cementitious material in the concrete

Operate stationary mixers with an automatic timing device. The timing device and discharge mechanismmust be interlocked such that during normal operation no part of the batch is discharged before thespecified mixing time has elapsed.

The total time from the intermingling of damp aggregates and all cementitious materials to the start ofmixing must not exceed 30 minutes.

The batch size must not exceed the manufacturer's guaranteed capacity.

For pavement or base concrete, install and maintain suitable batch counters in good operating conditionat job site batching plants and stationary mixers. The batch counters must indicate the exact number ofbatches proportioned and mixed.

Mix and deliver the concrete to the job site by one of the following methods:

1. Central-mixed concrete, in which the concrete is mixed completely in a stationary mixer andtransported to the delivery point in a truck agitator or nonagitating hauling equipment.

2. Shrink-mixed concrete, in which the concrete is mixed partially in a stationary mixer and the mixing iscompleted in a truck mixer.

3. Transit-mixed concrete, in which the concrete is mixed completely in a truck mixer.

Agitators must be truck mixers operating at agitation speed or truck agitators. Each mixer and agitatormust have a metal plate attached in a prominent place that clearly shows:

1. Various uses for which the equipment is designed2. Manufacturer's guaranteed drum or container capacity in terms of the volume of mixed concrete3. Rotation speed of the mixing drum or blades

Truck mixers must have an electrically or mechanically actuated revolution counter that readily allowsverification of the number of revolutions of the drum or blades.

For shrink-mixed concrete, transfer concrete that has been partially mixed at a central plant into a truckmixer and comply with the specifications for transit-mixed concrete. Partial mixing in a central plant doesnot count toward the number of revolutions at mixing speed.

90-1.02G(3) Transporting Mixed ConcreteConform with ASTM C94 / C94M Standard Specification for Ready-Mixed Concrete

90-1.02G(4) Time or Quantity of MixingMixing of the concrete in a stationary mixer must continue for the required mixing time after allingredients, except water and admixture that is added with the water, are in the mixing compartment ofthe mixer before any part of the batch is released. The transfer time in multiple drum mixers must not becounted as part of the required mixing time.

For concrete used in concrete structures other than minor structures, the mixing time in a stationary mixermust be at least 90 seconds and no more than 5 minutes, except that if authorized the minimum mixingtime may be reduced to 50 seconds. For all other concrete, the mixing time must be at least 50 secondsand no more than 5 minutes.

The minimum required revolutions at the mixing speed for transit-mixed concrete must be at least thatrecommended by the mixer manufacturer and must be enough to produce uniform concrete under section90-1.02A.

90-1.02G(5) Hand MixingHand-mixed concrete must be made in batches of 1/3 cu yd or less.

Use the following procedure to make hand-mixed concrete:

1. Measure the quantity of coarse aggregate in measuring boxes.2. Spread the coarse aggregate on a watertight, level platform.

95-1.01 DESCRIPTIONSection 95-1 includes general specifications for mixing and applying epoxy for highway construction.

Furnish epoxy as 2 components and mix them together at the job site.

The 2 proportioned epoxy components define a kit when packaged together.

95-1.02 SAMPLING AND TESTINGSubmit a certificate of compliance for epoxy.

95-1.03 PACKAGING, LABELING, AND STORINGEach component must be packaged in a container of a size that complies with the epoxy manufacturer'sinstructions for proportions.

Component containers must be sealed and not leak. Containers must not react with components.

The container for each component must be clearly labeled by the epoxy manufacturer with the followinginformation:

1. ASTM C 881/C 881M class and type2. Component designation, A or B3. Manufacturer's name4. Manufacture date5. Batch number6. Expiration date7. Directions for use8. Warnings or precautions required by State and federal laws and regulations

Store components at temperatures greater than 35 degrees F.

95-1.04 DIRECTION FOR USEMix and apply the epoxy under the manufacturer's instructions.

Do not use a component if any of the following occur:

1. Evidence of crystallization or thickening2. Settled pigments that cannot be readily dispersed with a paddle3. Component is older than the manufacturer's recommended expiration date

Thoroughly stir each component before mixing a kit. Do not mix partial kits. Do not add solvents.

Automatic mixing equipment must have positive displacement pumps and be capable of metering a 2-component mix in the specified ratio ± 5 percent by volume of either component.

Mix the 2 components until no trace of black or white streaks is present in the mixed epoxy.

Clean surfaces to receive the epoxy of rust, paint, grease, asphalt, loose, and deleterious material. Applythe epoxy and place materials to be bonded before the epoxy starts to thicken. Do not use epoxy that hasexceeded its working life.

95-2 TYPES OF EPOXIES95-2.01 EPOXY BINDEREpoxy binder must be low viscosity epoxy formulated primarily for use in:

1. Making HS epoxy concrete and epoxy mortar2. Pressure grouting cracks in concrete

For load bearing applications, the epoxy must comply with ASTM C 881/C 881M, Type IV, Grade 1, ClassB or C.

For nonload bearing applications, the epoxy must comply with ASTM C 881/C 881M, Type I, Grade 1,Class B or C.

Use Class B whenever the surface temperature is from 40 to 60 degrees F. Use Class C whenever thesurface temperature is above 60 degrees F.

Thoroughly mix the components before adding aggregate if the epoxy is used as binder for HS epoxyconcrete or epoxy mortar. The mix proportions must be 1 part epoxy to 4 parts aggregate by volume.Aggregate must be clean and have a moisture content of not more than 0.50 percent when tested underCalifornia Test 226. Prime surfaces with epoxy immediately before placing epoxy concrete or mortar.

95-2.02 RESERVED95-2.03 EPOXY ADHESIVE FOR BONDING FRESHLY MIXED CONCRETE TO HARDENEDCONCRETEEpoxy adhesive for bonding freshly mixed concrete to hardened concrete must comply with ASTM C881/C 881M, Type V, Grade 2, Class B or C.

Use Class B whenever the surface temperature is from 40 to 60 degrees F or if a faster cure is required.Use Class C whenever the surface temperature is above 60 degrees F.

Coat the blast-cleaned concrete surface with epoxy using a brush or roller. Place freshly mixed concretewhile the epoxy is tacky. Apply a new coat of epoxy if the epoxy sets.

95-2.04 RAPID SET EPOXY ADHESIVE FOR PAVEMENT MARKERSRapid set epoxy adhesive for bonding pavement markers to concrete and HMA must comply with ASTMC 881/C 881M, Type IV, Grade 3, Class B or C, except the gel time may be less than 30 minutes.
