Delivery, Storage, arid. Handling .. Storage of material is allowed in a properly sealed and insulated system for up to 24 hours except that Stone Matrix Asphalt (SMA); Open-Graded Friction Course (OGFC), or Porous European Mix (PEM) mixtures shall not be stored more than 12 hours. Mixtures other than S~ OGFC, or PEM may be stored up to 72 hours in a sealed and insulated system, equipped with an auxiliary inert gas system, with the Engineer's appJ;"oval. Segregation, lumpiness, drain-down, orstiffuess of storedmixture is cause for rejection of the mixture. The Engineer will not approve using a storage oT surge bin ifthe mixture segregates, loses excessive heat,. or oxidizes during storage. The Engineer may obtain mixture samples or recover asphalt cement according to GDT 119. AASHTO T 202 and T 49 will be used to perform viscosity and penetration tests to determine how much asphalt hardening has occurred. . A. Vehicles for Transporting and Delivering Mixtures Ensure that trucks used for hauling bituminous mixtures have tight, clean, smooth beds. Follow these guidelines when preparing vehicles to transport bituminous mixtures: I. .Use an approved releasing agent from QPL 39 in the transporting vehicle beds, if necessary, to prevent the mixture from sticking to the bed. Ensure that the releasing agent is not detrimental to the mixture. When applying the agent, drain the excess agent from the bed before loading. Remove from the project any transporting vehicles determined to contain unapproved releasing agents. . 2. Protect the mixture with a waterproof cover large enough to extend over the sides and ends of the bed. Securely fasten the waterproof cover before the vehicle begins moving. J. Insulate the front end and sides of each bed with an insulating material with the following specifications: · Consists of builders insulating board or equivalent · Has a minimum "R" value of 4.0 · Can withstand approximately 400 OF (200 oC) temperatures Install the insulating material soit is protected from loss and contamination. A "Heat Dump Body;' may be used in lieu of insulation of the bed. "Heat Dump Body" refers to any approved transport vehicle that is capable of diverting engine exhaust and transmitting heat evenly throughout the dump body to keep asphalt. at required temperature. Mark the "Heat Dump Body" clearly with "OPEN" and "CLOSE" position at the exhaUst diverter. Install a padlock and lock it in the "OPEN" position when the "Heat Dump Body" is used to transport bituminous mixturesl . 4.

When collecting airborne aggregate particles and returning them to the mixture, have the return system meter all or part of the collected dust uniformly into the aggregate mixture and waste the excess. The collected dust percentage returned to the mixture is subject to the Engineer's approvaL b. When the collected dust is returned directly to the hot aggregate flow, interlock the dust feeder with the hot aggregate flow and meter the flow to maintain a flow that is constant, proportioned; and . uniform. . 5. Hydrated Lime Treatment System When hydrated lime is required as a mixture ingredient: . . a. Use a separate bin and feed system to store and proportion the required quantity into the mixture. b. Ensure that the aggregate is uniformly coated with hydrated lime aggregate before adding the . bituminous material to the mixture~ Add the hydrated lime so that it will not become entrained in the exhaust system of the drier or plant. c. Control the fceder system with a proportioning device that meets these specifications: · Is accUrate to within:l: 10 percent of the amount required · Has a convenient and accurate means of calibration · Interlocks with the aggregate feed or weigh system to maintain the correct proportions for all rates . of production and batch sizes and to ensure iliat mixture produced is properly treated with lime Provide flow indicators or sensing devices for the hydrated lime system and interlock them with the plant controls to interrupt mixture production if hydrated lime introduction fails to meet the required target value after no longer than 60 seconds. 6. NetWeight Weighing Mechanisms Certify the accuracy of the net weight weighing mechanisms by an approved registered scale serviceperson at least once every 6 months. Check the accuracy of net weight weighing mechanisms at the beginning of Project production and thereafter as directed by the Engineer. Check mechanism accuracy as follows: a. Weigh a load on a set of certified commercial truck scales. Ensure that the difference between the ---------------- -:.....-flrtnledl~falIR~Twetghrand that obtained from the commercial scales is no greater than 4 Ibs/I,OOO lbs (4 kglMg) of load. Check the accuracy of the bitumen scales as follows: · Use standard test weights. · If the checks indicate that printed weights are out of tolerance, have a registered scale serviceperSon check the batch scales and certify the accuracy of the printer. · While the printer system is out oftolerance and before its adjustment, continue production only if using a set of certified truck scales to determine the truck weights. b. Have plants that use batch scales maintain ten 50 Ib (25 kg) standard test weights at the plant site to check batching scale accuracy. . Ens.ure that plant scales that are used Only to proportion mixture ingredients, not to determine pay . quantities, are within two percent throughout the range. C.

As wide and deep as indicated on the Plans · True to line, grade, and cross section · Smooth · Uniform in density and texture a. Continuous Line and Grade Reference ControL Furnish, place, and maintain the supports, wires, devices, and materialstequired to provide continuous line and grade reference control to the automatic paver control system. . . b. Automatic Screed Control System. Equip the bituminous pavers with an automatic screed control system actuated from sensor-directed mechanisms or devices that will maintain the paver screed at a pre-determined transverse slope and elevation to obtain the required surface. c. Transverse Slope Controller. Use a transverse slope controller capable of maintaining the screed at the desired siope within:l: 0.1 percent. Do not use continuous paving set-ups that result in unbalanced screed widths or off-center breaks in the main screed cross section unless approved by the Engineer~ d. Screed Control. Equip the paver to permit the following four modes of screed control. The method used shall be approved by the Engineer. · Automatic grade sensing and slope control · Automatic dual grade sensing · Combination autpmatic and manual control · Total manual control Ensure that the controls are referenced with a taut string or wire set to grade, or with a ski-type device or mobile reference at least 30 ft (9 m) long when using a conventional ski. A non-contacting laser or sonar-type ski with atleast four referencing mobile stations may be used with a reference at least 24 ft. (7.3 m)long. Under limited conditions, a short ski or shoe may be substituted for a long ski on the second paver operating in tandem, or when the reference plane is a newly placed adjacent lane. Automatic screed control is required on all Projects; however, when the Engineer determines that Project conditions prohibit the use of such controls, the Engineer may waive the grade control, or slope control requirements, or both. e. Paver Screed Extension. When the laydown width requires a paver screed extension, use bolt~n screed extensions to extend the screeds, or use an approved mechanical screed extension device. When the screed is extended, add auger extensions to assure a length of no more than 18 inches from the auger to the end gate of the paver. Auger extensio~may be omitted when paving variable widths. Ensure the paver is equipped with tunnel extensions when the screed and augers are extended. - f. 30 - 45 Degree Wedge. When shown on/required by the plans: equip the paver to ensure a 30 degree minimum up to a 45 degree maximum wedge along the outside edge of the roadway (measured from the horizontal plane) is in place after final compaction on the fmalsutface course. Use an approved mechanical device that will: · Apply compactive effort to the asphalt mixture to eliminate objectionable voids as the mixture passes thiough the wedge device · Produce a wedge with a uniform texture, shape, and density while automatically adjusting to varying heights encountered along the roadway shoulder. NOTE: Do not use extendible strike-off devices instead of approved screed extensions. Only use a strike-:-off device in areas that would normally be luted in by hand labor. 4. Compaction Equipment Ensure that the compaction equipment is in good mechanical condition and can compact the mixture to the required density. The compaction equipment number, type, size, operation, and conditioIl is subject to the Engineer's approval. 400.3.03 Preparation A.

(9.5 mm) 3.5% 4.0% No.4 (4.75 mm) 3.5% 3;5% No.8 (2.36 mm) 2.5% 3;0% No. 200 (75 ~m) 2.0% 2.0% A.C. 0.4% 0.5% (1) Ifte~t comparisons are within these tolerances: · Continue production · Use the Contractor's tests for acceptance of the lot (2) If test comparisons are not within these tolerances: · Another Departmental technician will test the corresponding referee sample · Results of the referee sample will be compared to the respective contractor and Departmental tests using the tolerance for comparison samples given above. (a) If referee test results are within the above tolerances when compared to the Contractor acceptance test, use the Contractor's testfor.acceptance of the effected lot. (b) Ifreferee test results are.not within the above tolerances when compared to the Contractor acceptance test, the Department will review the Contractor's quality control methods and determine if a thorough investigation is needed. b) Quality Assurance Sampling and Testing (1) Randomly take a minimum of two quality assurance samples from the lesser oftive days . or five lots of production regardless of mix type or number of projects. (2) Compare test deviation from job mix formula to Mixture Control Tolerances in Section 828. If results are outside these tolerances, another sample from the respective mix may be taken. NOTE: For leveling courses less than no Ib/yd2 (60 kg/m2) that have quality assurance test results outside the Mixture Control Tolerances of Section 828, use the Department's test results only. If test results of the additional sample are not within Mixture Control Tolerances, the Department will take the following action: · Take random samples from throughout the Iotas in Subsection 400.3.06.A.3.b.3 and use these test results for acceptance and in calculations for the monthly plant rating. Determine if the Contractor's quality control program is satisfactory and require prompt corrective action by the Contractor if specification requirements are not being met. . · Determine if the QCT has not followed Departmental procedures or has provided erroneous information. .. Take sainples of any in-place mixture represented by uriacceptable QCT tests and use the additional sample results for acceptance and in calculations for the monthly plant rating. The Contractor QCT tests will not be included in the monthly plant rating. . B. Compaction Determine the mixture compaction using either GDT 39 or GDT 59. The compaction is accepted in lots defmed in Subsection 400.3.06.A "AccevtancePlans for Gradation and Asphalt Cement Content" and is within the. same lot boundaries as the mixture acceptance. . 1. Calculate Pqvement Mean Air Voids The Department will calculate the pavement air voids placed within each lot as follows: a. One test per sub-lot. · Lots 2: 500 tons of mix should be divided into 5 sub-lots of equal distance. · Lots < 500 tons of mix should be comprised of a sub-lot or sub-lots consisting of up to 100 tons of mix each. There may be less than 5 sub-lots. . b. Average the results of all tests run on randomly selected sites in that lot. c. Select the random sites using GDT 73. Density tests are not required for asphaltic concrete placed at 125 Ibs/yd2 (68 kglm2) or less, 4:75 rom mix and mixes placed as variable depth or width leveling. Compact these courses to the Engineer's satisfaction.. Density tests will not be performed on turn-outs and driveways. .The targeted maximum Pavement Mean Air Void content for all Superpave mixtures is 5.0.percent. Ensure that the maximum Pavement Mean Air Voids for all Superpave mixtures does not exceed 7.8 percent. The maximum Pavement Mean Air Voids for 2 foot shoulder widening is 9.0 percent. The ~djustment period for density shall be ~ee lots or thr~e production days, whichever is less, in order for the contractor to ensure maximum compactive effort has been achieved which will yield no more than the specified maximum allowed Mean Air Voids. If the contractor needs to adjust the mixtureto improve density results, a change in the job mix formula may be requested for approval during the adjustinent period so. long as the following values are not exceeded: · Coarse pay sieve :!: 4% · No.8 (2.36 rnm) sieve :!: 2% · No. 200 (75 flm) sieve :!: 1% · Asphalt Content :!: 0.2% · All value changes must still be within specification limits If the Office of Materials and Research is satisfied that the contractor has exerted the maximum compactive effort and is not able to maintain Pavement Mean Air Voids at no more than 7.8%, the Engineer may . establish a maximum target for Pavement Mean Air Voids. If the Pavement Mean Air Voids within a Lot exceeds 7.8 (or 100% of the maximum target air voids, if established is not maintained); the Engineer may stop the paving operation until appropriate steps are taken by the Contractor to correct the deficiency. Upon approval of the Engineer, the paving operation may be restarted but will be limited to a 1000 ft (300 m) test section to verify that the corrective action taken will result in satisfactory density. Continued operation may not be permitted if the Pavement Mean Air Voids fail to meet the specified density requirements. 2. Obtain Uniform Compaction For a lot to be accepted for compaction, the air void range cannot exceed 4 percent for new construction or 5 . percent for resurfacing projects. The range is the difference between the highest and lowest acceptance test results within the affected lot. e. Surface Tolerance In this Specification, pavement courses to be overlaid with an Open-Graded Friction Course or PEM are considered surface courses. Other asphalt paving is subjeCt to straightedge and visual inspection and irregularity correction as shown below: 1. Visual and Straightedge Inspection . Paving is subj ect to. visual and straightedge inspection during and after construction operatioris until Final Acceptance. Locate surface irregularities as follows: a. Keep a 10 ft (3 m) straightedge near the paving operation to measure surface irregularities on courses. Provide the straightedge and the labor for its use, b. Inspect the base, intermediate, and surface course surfaces with the straightedge to detect irregularities. . . . c. Correct m-egularities that exceed 3/16 in. in 10 ft (5 mm in 3 m) for base and intermediate courses, and 118 in. in 10 ft (3 mm in 3 m) for surface courses. . Mixture or operating techniques will be stopped if irregularities such as rippling, tearing, or pulling occur and the Engineer suspects a continuing equipment problem..Stop the paving operation and correct the problem. . D. Reevaluation of Lots Reevaluation of Lots and acceptance will be based on Department evaluations. The Department will be reimbursed by the Contractor for all costs of these evaluations. Request for reevaluation shall be made withIn 5 working days of notification of the lot results. E. Segregated Mixture Prevent mixture placement that yields a segregated mat by following production, storage, loading, placing, and handling procedures. Also, make needed plant modifications and provide necessary auxiliary equipment (See Subsection 400.1.01. "Definitions.") If the mixture is segregated in the fmished mat, the Department will take actions based on the degree of segregation. The actions are described below. 1. Unquestionably Unacceptable Segregation When the Engineer detennines that the segregation in the finished mat is unquestionably unacceptable, follow these measures: . . a. Suspend Work and require the Contractor to take positive corrective action. The Department will evaluate the segregated areas to determine the extent of the corrective work to thein-place mat as follows: · Perform extraction and gradation analysis by taking 6 in (I 50 mm) cores from typical, visually unacceptable segregated areas. · Determine the corrective work according to Subsection 400.3.06.E.3. b. Requirethe Contractor to submit a written plan of measures and actions to prevent further. segregation. Work will not continue witil the plim is submitted to and approved by the Department c. When work resumes; place a test section not to exceed 500 tons (500 Mg) of the affected mixture for the Department to evaluate. If a few loads show that corrective actions were not adequate, follow the. measures above beginning with step l.a. above. If the problem is solved, Work may Continue. 2. Unacceptable Segregation Suspected When the Engineer observes segregation in the fmished mat and suspects that it may be unacceptable, follow these measures: . a, Allow work to continue at Contractor's risk. b. Require Contractor to immediately and continually adjust operation until the visually apparent segregated areas are eliminated from the finished mat The Department will immediately investigate to determine the severity of the apparent segregation as follows: · Take 6 in (150 mm) cores from typical areas of suspect segregation. · Test the cores for compliance with the mixture control tolerances in Section 828. When these tolerances are exceeded, suspend work for corrective action as outlined in Subsection 400.3.06.E.3. 3. . Corrective Work a Remove and replace (at the Contractor's expense) any segregated area where the gradation on the control sieves is found to vary 10 percent or more from the approved job mix formula, the asphalt cement varies 1.0% or more from the ,approved job mix formula, or if in-place air voids exceed 12.5% based on GDT 39. The control sieves for each mix type are shown in Subsection 400.5.0I.B "Determine Lot Acceptance." . . b. Subsurface mixes. For subsurface mixes, limit removal and replacement to the full lane width and no less than 10 ft. (3 m) long and as approved by tlJ.e Engineer. . . c. Surface Mixes. For surface mixes, ensure that removal and replacement is not less than the full width of the affected lane and rio less than the length of the affected areas as determined by the Engineer. -Surface tolerance requirements apply to the corrected areas for both subsurface and surface mixes. 400.3.07 Contractor Warranty and Maintenance A.
