JOB GUIDE CONCRETE PAVING PLANT MONITOR 1. Review the Contract and Plans:
• Become familiar with applicable specifications based upon the size of the project and delivery method of concrete.
• Review incentives and disincentives available. • Check Schedule of Materials Control for testing rates and sample sizes. • Attend the pre-construction meeting if possible.
2. Preliminary Testing and Mix Design Requirements:
• Verify the Contractor’s aggregate sources and make sure preliminary testing if required has been done well in advance of the project start date.
• Make sure the Contractor submits mix designs and gradations/job mix formulas (JMF) to the Concrete Engineering Unit for review and approval a minimum of 21 days prior to initial placement of mix design.
3. Become familiar with concrete batching and mixing equipment and the duties of the Contractor. • Obtain the Contractor’s organizational chart listing names, phone numbers and emails of
individuals responsible for mix design, process control administration and inspection. • Inspect batch trucks for compliance with specifications
4. Complete a Concrete Paving Contact Report (Form 2164): • Review the Contractor’s concrete paving combination plant-lab office for compliance. • Verify whether the Contractor has an electronic means of communication (email) • Check that scales and water meter are calibrated • Obtain pre-production coarse aggregate samples for quality testing in accordance with
the Schedule of Materials Control. Fill out Aggregate Sample I.D. cards completely and include with lab samples.
• Verify cement, fly ash, and admixtures are on the Certified/Approved Products list. • Obtain cement, fly ash, and admixtures samples from the Contractor per the Schedule of
Materials Control. Provide sampling containers and witness sampling when possible. • Include cementitious invoices when submitting samples to the laboratory for testing. • Fill out lab sample I.D. cards completely and enclose them with cement, fly ash, and
admixture samples. 5. During Concrete Production:
• Monitor stockpiling and loading of delivered aggregates. • Observe scale operation and loading of trucks at a minimum of 2 hour intervals
throughout the day. • Check field hoppers for contamination. If contaminated, have Contractor empty storage
and weigh hoppers and re-charge. • Review mix designs and ensure the Contractor is using correct mix design weights. • Check that batch weights are adjusted in accordance with current moisture tests. • Ensure compliance with minimum and maximum mixing times.
6. Complete Concrete Ingredient Summary Daily:
• Collect a production summary in an electronic format of the daily total concrete produced and daily total ingredient quantities (aggregate, cementitious and water) including the percent overrun/underrun.
• Collect final project total quantities for concrete produced and ingredients in an electronic format including the percent overrun/underrun.
• Verify daily and final quantities are within tolerances as required by the Specifications. 7. Perform Moisture Tests and Water Content Verification Testing (Microwave Oven):
• Verify contractor performs start-up moisture tests. • Take additional moistures whenever moisture appearance of delivered aggregate seems
to vary or batch water deviates greatly from previous loads. • Use Concrete W/C Ratio Calculation Worksheet to determine moisture contents, batch
ticket, w/c ratios, unit weight, microwave oven w/c ratios, charting and w/c ratio. incentive/disincentives.
• Review water/cementitious ratio results for compliance with project specifications and verify with microwave oven testing.
8. Aggregate Gradation Testing:
• Review Contract and Contractor Mix Design to determine gradation testing requirements.
• Use Well-graded Concrete Aggregate Worksheet to calculate gradations in the field. • Verify Contractor is using Well-graded Concrete Aggregate Worksheet for gradations
test, charting and well-graded incentives. • Review Contractor’s tests for compliance and compare to the Agency test results (split
samples). • If submitting gradation samples to the lab, fill out Aggregate Sample I.D. cards
completely including the JMF number found on the Contractor mix design and the QC Gradation results. Identify “QA Gradation” on ID card.
• Determine if Contractor is eligible for well-graded aggregate incentives. Review the Contractor’s Well-Graded Aggregate Summary Worksheet.
9. % Passing 75 µm (#200) Sieve:
• Perform all percent passing the #200 (75 µm) sieve at the Contractor’s plant site. • Verify Contractor washed all fine aggregate gradations to determine the percent passing
the #200 (75 µm) sieve. • Use Well-graded Concrete Aggregate Worksheet to calculate the percent passing the
#200 (75 µm) sieve in the field. • Review the Contractor’s percent passing the #200 (75 µm) sieve for the coarse
aggregate results to determine compliance or if additional testing is required and compare to Agency results.
10. Aggregate Quality Sampling:
• Fill out Aggregate Sample I.D. cards completely and record the Contractor and Agency -#200 (75 µm) test results.
• Identify Quality samples with a “Q” including the specification reference (Spec 3126 for sand and 3137.2D3 for coarse aggregate) on ID card.
• Identify the Quality Companion samples with a “Q”.
11. Coarse Aggregate Quality Sampling:
• If coarse aggregate quality incentive/disincentive applies, determine when random samples will be taken in accordance with the Schedule of Materials Control using the Coarse Aggregate Quality Incentive/Disincentive Worksheet.
• Fill out Aggregate Sample I.D. cards completely and enclose with lab samples. Identify Incentive samples with “I/D” on ID card.
12. Alkali Silica Reactivity (ASR) Sampling: • Obtain samples of cement, supplementary cementitious materials (fly ash or slag) and
sand in accordance with the Schedule of Materials Control. • Fill out the Sample I.D. card completely and enclose with lab samples. Identify ASR
sample with “Project Specific ASR Testing” on ID card.
13. Contractor Records and Charts: • Obtain the Contractor’s on-site QC records and charts on a daily basis or otherwise
directed by the Engineer. • Review the Contractor’s on-site QC records and charts for accuracy and completeness. • Obtain batch tickets on a daily basis or otherwise directed by the Engineer.
14. Maintain a daily diary:
• Includes hours of production, equipment, weather, concrete air content test results conducted at the plant, air temperatures, concrete yardage totals, and problems or unique circumstances encountered.
15. Documention of test results:
• Record all calculated w/c ratio test results and mix design data along with all field results on the Weekly Concrete Report (MnDOT Form 2448).
• Contractor field test results can be entered on a separate form and submitted with the Weekly Concrete Report.
16. Submit the following to the MnDOT Concrete Engineering Unit: • Contact Report • Weekly Concrete Reports – Form 2448 • W/C Ratio Incentive Calculation Worksheets • Well-graded Aggregate Incentive Worksheets • Quality Incentive/Disincentive Worksheets

JOB GUIDE CONCRETE PAVING INSPECTION 1. Review Contract and Plans:
• Obtain plans and special provisions and study them in detail. • Attend the pre-construction meeting.
2. Determine Random Numbers:
• Determine random numbers for testing locations using the Probing, Coring, Texture and MIT-SCAN T2 Report.
3. Become familiar with concrete paving equipment and paving operations.
• Check paving equipment for proper adjustment and compliance with specifications. • Understand the function of each piece of equipment. • Become familiar with paving sequence and review field controls for line and grade. • Verify string line is set sufficiently in advance to avoid delays. • Check vibration equipment and verify vibration monitors are operating correctly. • Verify that utility work and conduits are complete. Pre-locate utility fixtures to be
incorporated into the pavement.
4. Placement on Grade: • Check that the grade is in a moist condition ahead of the concrete placement. • Trucks hauling concrete are not allowed on the finished grade unless authorized by the
Engineer.
5. Placement on Asphalt: • Clean the milled surface by sweeping and patching, or as directed by the Engineer. • Maintain the asphalt surface in a moist condition and at a surface temperature not
greater than 120 °F [50 °C] before or during concrete placement. • Ensure the Contractor trucks don’t tear up the asphalt during turning movements.
6. Placement on Geotextile: • Clean the surface of the concrete prior to placing the geotextile fabric by power
sweeping and air blasting. • Ensure fabric is tight without excess wrinkles or folds. • Maintain the surface in a slightly damp, not saturated, condition before placing the
concrete. • Ensure the Contractor trucks don’t tear up the geotextile during turning movements.
7. Reinforcing Steel and Keyway Placement:
• Check size, spacing, and placement of reinforcing steel, and any other special reinforced panels.
• Verify proper reinforcement size, grade, lap ties, depth and spacing. • Check size and length of centerline steel and keyway tie steel. • Check if the required mechanical placer is placing it at the proper depth. • Assure location at proper elevation. • Make sure bars are the right size and length, and properly spaced. • Make sure keyway tie steel is not placed at a doweled joint.
8. Dowel Basket Assemblies:
• Check proper size and type of dowel bar assembly. • Review Quality Control Plan for Anchoring Dowel Basket Assemblies. • Observe for approval the Contractor’s fastening method for dowel bar assemblies before
the beginning of concrete placement and each day prior to beginning paving. • Check dowel bar assemblies for proper placement to assure that they are parallel with
the base and centerline of road, properly supported and staked. • Make sure dowel baskets are securely anchored on the bottom rail using the correct
number of anchors. Refer to the Standard Plates for details. • If a bond breaker layer is used, make sure dowel baskets are securely fastened through
the bond breaker layer into the concrete below. • Check the placement of dowel assemblies at catch basins and manholes; keep joint at
least 3 ft (1 m) from structure. • Make sure an approved form release agent has been applied to dowel bars. • Confirm joint sawing locations are marked at the same location as the dowel baskets. • Mutually use the MIT-SCAN T2 device for locating dowel basket assemblies in the
plastic concrete.
9. When using forms: • Inspect pavement forms, as necessary, to ensure cleanliness and compliance with form
requirements. • Verify the forms are set to the alignment and grade shown on the plans for a distance
equal to at least 3 hours ahead of concrete placement. • If rain or cold weather occurs, ensure forms are removed and reset as necessary to
allow drainage.
10. Verify the Contractor’s prepared for inclement weather (rain or cold weather conditions). • Review the Contractor’s written cold weather protection plan.
11. During Concrete Placement: • Make sure concrete is placed within the time specification. • Check that no concrete is lost on the haul road or sticks in the truck after it dumps. • Stencil the stationing into the edge of the pavement every 500 ft (200 m) as directed by
the Engineer. • When placing concrete adjacent to in-place concrete pavement, protect the existing
transverse joints and the edges of the pavement. • Set manhole and catch basin frames or rings to the elevation shown on the plans during
the paving operations. 12. Monitor paving operation for continuous placement and consolidation of concrete.
• Make sure concrete is spread uniformly and ensure there is uniform strike-off. • Check to see that paver is not over or under loaded, and that concrete is “rolling” not
“sliding” in front of the screed. • Check if vibrating tubes are operating • Spot check vibration equipment daily and verify vibration monitors are operating
correctly. • Computerized vibration monitors are required on slipform pavers. Obtain an electronic
copy of all vibration monitor data from the Contractor at the end of the project.
13. Concrete Appearance:
• Check that the concrete is maintained at a uniform consistency. • Monitor the surface and edge slump. • Make sure the tamping bar is properly adjusted so large aggregate is tucked below the
surface and not dragged.
14. Verify pavement dimensions: • Measure pavement width, thickness, crown, superelevation, edge slump, and joints
match to ensure it meets plan requirements. • Observe the Contractor’s probing operations.
15. Air Content and Slump Testing in accordance with the Schedule of Materials Control:
• Observe Contractor perform air content testing for slipform placement before and after consolidation.
• Perform air content testing for slipform placement before and after. • Observe Contractor perform air content and slump testing for fixed form placement. • Verify the air content and slump test results are within Specifications. • Record all test results on the Weekly Concrete Report (MnDOT Form 2448). Contractor
test results can be entered on a separate form and submitted with the Weekly Concrete Report.
16. Flexural Strength Testing (Beams):
• Observe Contractor make beams as required in the Schedule of Materials Control. • Contractor removes beams from boxes, cleans boxes, and reassembles boxes. • Agency cures and breaks beams. • Record beam break results on Concrete Test Beam Data (MnDOT Form 2162). • Verify minimum strength requirements for opening pavements to construction and to
general traffic. 17. Finishing and Texturing:
• Do not allow the Contractor to add water to the surface of the concrete to aid in finishing without the approval of the Engineer.
• Check surface using a 10 ft (3 m) straightedge to check for tolerance.
18. Ensure texturing is properly performed at appropriate time. • Check that the texture marks are uniform and parallel to centerline. • Provide random sand patch test locations to the Contractor. • Verify texture by observing Contractor sand patch testing. • Review the Contractor’s Concrete Texture results for compliance.
19. Headers:
• Construct construction headers, temporary headers, and permanent headers as shown on the plans and Standard Plates
• Do not allow incorporating any concrete accumulated in the grout box of the paver into the pavement. Construct all headers such that the concrete contained in the grout box is removed from the project.
• Use internal vibration to consolidate the concrete along header joints before final finishing.
20. Curing:
• Verify an approved curing compound lot/batch is used by checking the Approved/Qualified Products list.
• Check application rate of curing compound for uniformity, yield, and timely placement. • Ensure compliance with cold weather protection requirements.
21. Sawing Joints:
• Check joint sawing operation. Check joint location adjustments at side streets, inlets, manholes, etc.
• Check appearance, depth, and width of sawed joints on a daily basis. No raveling and no random cracking should occur at the time of initial sawing.
• Widening of the joints shall not occur until the concrete is at least 24 hours old. 22. Sealing Joints:
• Verify joints are clean and dry before approving. • Do not allow traffic on the slab until the widened joints are sealed.
23. MIT-SCAN T2 Testing on the Hardened Concrete:
• Provide random testing locations to the Contractor. • Observe the Contractor scan the tie bar steel and dowel bar anchoring within 24 hours of
pavement placement as required in the Special Provisions. 24. Thickness (Cores) Verification:
• Observe the Contractor’s coring operation to verify authenticity. • Field measure concrete cores, record the results on the Field Coring Report and submit
cores to the MnDOT Laboratory for official measurement and testing.
25. Pavement Surface Smoothness: • Make sure the Inertial Profiler (IP) is certified and displaying the certification sticker on
the vehicle. Make sure IP operator is certified. See MnDOT Smoothness website for a list of the certified IP’s, required settings for individual certified IP’s, and certified operators.
• Observe all Contractor profiling, unless approved by the Engineer. • Review the Contractor’s printouts containing the IP’s settings, each segment’s left and
right IRI values, the signature of the operator and electronic ERD files submitted on the same day of the profiling.
• Review the Smoothness Assurance analysis for contract compliance. • Determine if grinding is needed or required. • Check the final Concrete Profile Summary reports for contract compliance.
26. Maintain Agency Daily Diary:
• Includes hours of production, equipment, concrete temperatures, air content, slump reading, cylinder and beam data, stations paved, width, depth, yield, weather, air temperatures, and problems or unique circumstances encountered.
27. Document all field results along with calculated w/c ratio test results and mix design data on
the Weekly Concrete Report (MnDOT Form 2448) and submit to the Concrete Engineering Unit on a weekly basis. Contractor field test results can be entered on a separate form and submitted with the Weekly Concrete Report.
28. Submit the following to the MnDOT Concrete Engineering Unit:
• Weekly Concrete Reports – Form 2448 • Concrete Test Beam Data – Form 2162 • Field Coring Reports • Field Probing Reports • Concrete Texture Reports • Concrete Profile Summary Worksheets • Change orders and Supplemental Agreements
