The Engineer may obtain mixture samples or recover asphalt .cement according to GDT J 19. MSHTO 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: L 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 detririlental to the mixture. When applying the agent, drain the excess agent from the bed before loading. Remove fromthe 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 arid ends of the bed. Securely fasten the waterproof cover before the vehicle begins moving. 3. Insulate the front end and sides of each bed with an insulating material with the following specifications: · Consists of builders insulating board or equiyalent · Has a minimum "R" value of 4.0 . Can withstand approximately 400 OF (200 oC) temperatures . . Install the insulating material so it is protected from loss and contamination. A "Heat Duirtp Body" may be used in lieu of insulation of the bed. "Heat DumpBody" refers to any approved transport vehicle that is capable of -diverting engine exhaust and transmitting heat evenly throughout the dwnp body to keep asphalt at required temperature. Mark . the'~HeatDwnp Body' clearly with "OPEN" and "CLOSE" position at the eXhaust diverter. Install a padlock and lock it in the "OPEN' position when the "Heat Dwnp Body" is used to transport bituminous mixturegJ 4. Mark each transporting vehicle with a clearly visible identification number. 5. Create a hole in each side of the bed so that the temperatme of the loaded mixtme can be checked. The placement of these holes shall be located to assure that the thermometer is being placed in the hot mix asphaltic concrete.. " Office of Materials and Research Page 4 Section 40~Hot Mix Asphaltic Concrete Construction Ensure that the miXture is delivered to the roadway at a temperature within:l: 20 of (:I: 11 ot) of the temperature on the job miX formula. .. If the Engineer determines that a truck may be hazardous. to the Project .or adversely affect the quality of the work, remove the truck from th~ project. . B. Containers for Transporting, Conveying, and Storing Bituminous Material To transport, convey, and store bituminous material, use containers free of foreign materia,! and equipped with sample . valves. Bitumin01.1S material will not be accepted from conveying vehides if material has leaked or spilled from the containers. 400.3 Construction Requirements 400.3.02 Equipment Hot mix asphaltic concrete plants that produce miX for Department Use are governed by Quality Assurance for Hot Mix Asphaltic Concrete Plants in Georgia, Laboratory Standard Operating Procedure No. 27. The Engineer will approve the equipment used to transport and construct hot miX asphaltic concrete. Ensure that the equipment is in satisfactorymec~cal condition and can function properly during production and placement operations. Place the following equipment at the plant or project site: A. Field Laboratory Provide a field laboratory according to Section 152. B. Plant Equipment l. Scales Provide scales as follows: a. . . Furnish (at the Contractor's expense) scales to weigh bituminous plant miXtures, regardless of the measurement method for payment b. Ensure that the weight measuring devices that provide documentation comply with Subsection 109.0 L "Measurement and Quantities." c. When not using platform scales, provide weight devices that record the miXture net weights delivered to the truck. A net weight sy~tem will include, but is not limited to: . Hopper or batcher-type weight systems that deliver aSphaltic miXture directly to the truck . Fully automatic batching equipmentwith a digital recording device d. Use a net weight printing system only with automatic batching and mixing systems approved by the Engineer. . e. Ensure that the net weight scale mechanism or device manufacturer, installation, performance, arid operation meets the requirements in Subsection 109.01."Measur~ment and Ouantities". . f. Provide information on the Project tickets according to Department of Transportation SOP-IS. 2. Time-Locking Devices Furnish batch type asphalt plants with automatic time-locking devices. that control the mixing time automatically. Construct these devices so that the operator cannot shorten or eliminate any portion of the mixing cycle. 3. Surge-:- and Storage-Systems Provide surge and storage bins as follows: a. Ensure that bins for mixture storage are insulated and have a working seal, top and bottom, to prevent outside au infiltration and to maintain all inert .atmosphere during storage. Bins not intended as storage bins may be used as surge bins to hold hot mixtures for part of the working day. However, empty these surge bins completely at the end of the working day. . Office of Materials and Research Page 5 Section 40~Hot Mix Asphaltic Concrete Construction b. Ensure that surge and storage bins can retain a predetermined minimum level ofririxtirre in the bin when the tnicks are loaded c. Ensure that surge and storage systeIIlSdo not contribute to ririx segregation, lumpiness; draiD.-dowD,or stiffness. 4. Controls for Dust Collector Fines. Control dust collection as follows: a. When collecting airborne aggregate partic~es and returning them to the ririxture, have the return system meter all or part of the collected duSt uniformly into the aggregate ririxture and waste the excess. the collected dust percentage returned to the ririxtirre is subjectto 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 aIld meter the flow to maintain a flow that is constant,. proportioned, and uniform. 5. Hydrated Lime Treatment System . When hydrated lime is required as aririxtUre ingredient: a. Use a separate bin and feed system to store and proportion the required quantity into the ririxture. b. Ensure that the aggt'egate is unifoImly coated with hydrated lime aggregate before adding the bitmninouS material to the.mixture. Add the hydrated lime so that it will not become entrailled in the exhauSt system of the drier or plant. c. Control the feeder system with a proportioning device that meets these specifications: . Is accurate to within:!: 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 . pI:oduction and batch sizes and to ensure that 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 interiuptmixture production if hydrated lime introduction fails to meet the required target value after.no longer than 60 seconds. 6. Net Weight Weighing Mechanisms Certify the accuracy of the net weight weighing II?-echanisms 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 cOmniercialtiuck scales. Ensure that the difference between the pnnted total net weight and that obtained from the commercial scales is no greater than 4 Ibs/I,OOO lbs (4 kg/Mg) ofload. 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 andcertit)r the accuracy of the printer. . . . While the printer system is out oftolel1ll1ce and before its adjustment, continue production only ifuSing a set of certified truck scales to determine the truck weights. . b. Have plants that use batch scales maintain ten 50 lb (25 kg) standard test weights at the plant site to check . batching scale accuracy. Ensure that plant scales that are uSed only to proportion ririxture ingredients, not to determine pay quantities; are within two percent throughout the range. C. Equipment at Project Site 1. . Cleaning Equipment Provide sufficient hand tools and power equipment to clean the roadway surface before placing the bitmninouS tack coat. Use power equipment that complies with Subsection424.3.02.F. "Power Broom and PowerBlower." 2. Pressure Distributor To apply the bitmninouS tack coat, use a pressure distrIbutor that complies with Subsection 424.3.02.B. "Pressure Distributor:~ Office of Materials and Research Page 6 . . Section 400-Hot Mix Asphaltic Concrete C.onstruction 3. Bitwninous Pavers . . . To place hot mix asphaltic concrete, use bitwninous pavers that can spread and fmishcourses that are: . As wide and deep as indicated on the Plans · True to line, grade, and cross section . Smooth . . Unifomi in density and texture . . a. Continuous Line and Grade Reference Control; Furnish, place, and maintain the supports, wires, devices, and materials required 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 setisor~directed mechanisms or devices that will maintain the paver screed at a pre-detennined 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 slope within:i: 0.1 percent. Dp not use continuous. paving set-ups that result in unbalanced screed widths or ofr- . 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 automatic 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 at least four referencing mobile stationsrnay be used with a reference at least 24 ft. (7.3 m) long. Under limited conditions, a short ski or shoe maybe substituted for a long ski on the second paver operating in tandem, or when the reference plane is a newly placed adjacent lane.. Autoniatic screed control is required on all Projects; however, when the Engineer detennines 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-on scr.eed extensionS to extend thescreeds, 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.

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 kg/m2) or less, 4.75 mm 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 rilaximum 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 adjustment period for density shall be three lots or three 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 Office of Materials and Research Page 16 . . .. Section.40~Hof Mix ASphaltic'Concrete Construction contractor needs to adjust the mixture to improve density results, a change in the job mix formula may be requested . for approval during the adjustment period so long as the followmg values are not exceeq6d: · . Coarse pay sieve. . :!: 4% . · No.8 (2:36 nuil) sieve :!: 2% · No. 200 (75 J.UIl) sieve .:!: 1% · Asphalt Content :!: 0.2% · All value. changes must stillbe within specificationlimits . . If the Office of Mat~ria1s and Research is satisfied that the contractor has exerted the maximum compactive effort . aIid is nQt ~ble to maintairi Pavement Mean Air Voids at no more than 7.8%, the Engineer may establish a'maximU1,ll target for Pavemtmt Mean Air Voids. . If the Pavement Mean Air Voids Within a Lot exceeds7.8 (or 100% oftb.e maximum target air voids, if established is not maintained); the Engineer inay stop the paving operation until appropriate steps are taken.by the.COJitractor 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 tiken will result in satisfactory c;lensity. 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. C. 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: I.

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. ~'Defmitions.") If the mixture is segregated in the fmished mat, the Department will take actions based on t:b,e degree of segregation. The actions are described below. . 1. Unquestionably Unacceptable Segregation When the Engineer determines that the segregation in the finished mat is unquestionably unacceptable, follow these measures: Office of Materials and Research Page 17 Section 400-Hot Mix Asphaltic Concrete ConstruCtion 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 the in-place mat as follows: · Perform extraction and gradation analysis by taking 6 in (150 mm) cores from typical, visually unacceptable segregated areaS. . . · De~ermiriethe corrective work according to Subsection 400.3.06.E.3. . . b. Require the Contractor to submit a written plan of measures and actions to prevent further segregation. Work will not continue until the plan is submitted to and approved by the Department. c. When work-resumes, place a test section not to exceed 500 tons (500Mg;) of the affected mixture for the Department to eval~te. If a few loads show that corrective actioBS were not adequate, follow the measures above beginning with step La. above. If the problem is solved, Work may continue. 2. Unacceptable Segregation Suspected . When the Engineer obserVes segregation in. the finIshed 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: .. . T3.ke 6 m (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 anclreplace (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 400.5.01.B "Determine Lot Acceptance." b. .. Subsurface mixes. For subsuIface mixes, limit removal and replacement to the full lane width and no less than lOft. (3 m) long and as approved by the Engineer. c. Surface MiXes. For surface mixes, ensure that removal and replacement is not less than the full width of the affected lane and-no less than the length of the affected areas as determined.by the Engineer.
