After July I, 1991, State funded projects must comply with the requirements of Chapter 16 of Title 12 of the Official Code of Georgia Annotated, the Georgia Environmental Policy Act (GEP A), of 1991. In compliance with GEP A, those projects for which Federal funding is sought, and NEP A compliance is accomplished, are exempt from the requirements of GEP A. GEP A requires that environmental documentation be accomplished for County or City projects if more than 50 percent of the total project cost is funded by a grant of a State Agency or a grant of more that $250,000.00 is made by the State Agency to the municipality or County. The "responsible official of the government agency shall determine if a proposed governmental action is a proposed governmental action which may significantly adversely affect the quality of the environment." A. The Following Projects Would Not Significantly Adversely Affect The Quality Of The Environment: Non-land disturbing activities and rriinor land disturbing activities that would not be anticipated to significantly affect the quality of the environment include the following list. These types of projects funded with state money would not be subject to environmental assessment of any kind. Hearing procedures outline in GEP A would not be applicable. 1. Minor roadway and non-historic bridge projects. a., Modernization of an existing highway by resurfacing, restoration, rehabilitation, adding shoulders, widening a single lane or less in each direction and the addition of a median within previously disturbed exi~g right-of- way. b. Adding auxiliary lanes for localized purposes (weaving, climbing, speed changes, etc.) and correction substandard curves and intersections within previously disturbed existing right-or-way. c. Non-historic bridge replacement projects in existing alignment with no detour bridge. 2. Lighting, signing, pavement marking, signalization, freeway surveillance and control systems, and railroad protective devices. 3.

'- Office of State Aid Section 107-Legal Regulations and Responsibility to the Public B. The Following Projects May Not Significantly Adversely Affect The Quality Of The Environment: For projects that will cause land disturbance and for which there is no anticipation that the project may significantly adversely affect the quality of the environment, certain studies will be undertaken. These studies would serve to 'document. whether or not the County or municipality should anticipate that a project might significantly adversely affect the quality of the environment. Documentation of the studies will be accomplished through the use of the "GEP A Investigation Studies" checklist The types of projects that would fall under the category, would include: 1. Bridge replacement projects on new location or with a detour bridge, where there are no significant adverse impacts to historic or archaeological resources, no involvement with Federally listed threatened and endangered species and no significant adverse impact to wetlands. 2. Passing lanes, median additions and widening projects, where there are no significant adverse impacts to historic or archaeological resources, no involvement with Federally listed threatened and endangered species and no sign'ificant adverse impact to wetlands. 3. Safety and intersection improvements where there are no significant adverse impacts to historic or archaeological resources, no involvement with Federally listed threatened and endangered species and no significant adverse impact to wetlands. 4. Rest area projects and truck weigh stations with no purchase of additional right-of-way. . 5. New location projects where there are no significant adverse impacts to historic or archaeological resources, no involvement with Federally listed threatened and endangered species and no significant adverse impact to wetlands. If studies demonstrate that the project will not Significantly adversely affect the quality of the environment, project files will be documented. If studies demonstrate that the project may significantly adversely affect the quality of the environment, development of an environmental effects report (EER)' will be undertaken along with full GEP A compliance. C. The Following Projects May Significantly Adversely Affect The Quality Of The Environment: This category of projects may include major widening and new location projects. If such projects result in a significant adverse effect, an EER shall be prepared. D. EER Procedure: GEP A calls for consideration of the "cumulative effect of the proposed' government actions on the environment.. . ..if a series of proposed government actions are related either geographically or as logical parts in a chain of contemplattld actions." Therefore, EER's for sections of roadways to be widened or built as new location facilities will include all projects that are connected geographically or as logical parts in a chain of contemplated actions. 1. During preparation of an environmental effect report, the County or Municipality Will consult with and solicit comments from agencies that have jurisdiction by law, special expertise, or other interest with respect to environmental impacts. 2. In compliance with GEP A the following shall be contained in the HER, at a minimum: a. Cover sheet; b. Executive summary; c. Alternatives, including the no-build; d. Relevant environmental setting; Geology, soils, water supply and wetlands, floral fauna, archaeologylhistory, economic environment, en'7rgy, cultural resources; e.

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: 1. 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 detrimentalto 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 e}tend over the sides and 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 equivalent · 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 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 "~:at Dump Bo~y" cl~~rly with "OPEN" and "CLOSE" ~ositionat the exhaus~div:rter. In~tall a padlock and lock It III the "OPEN' pOSItion when the "Heat Dump Body" IS used to transport bItummous mIxture~ Section 400-Hot Mix Asphaltic Concrete Construction 4. Mark each transporting vehicle with a clearly visible identification number. 5. Create a hole in each side of the bed so that the temperature of the loaded mixture 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. Ensure that the mixture is delivered to the roadway at a terrperature within:J: 20 OF (:J: II oc) 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 the project. B. Containers for Transporting, Conveying, and Storing Bituminous Material To transport, convey, and store bituminous material, use containers free offoreign material and equipped with sample valves. Bituminous material will not be accepted from conveying vehicles if material has eaked or spilled from the containers. 400.3 Construction Requirements 400.3. 01 Personnel General Provisions lOl through 150. 400.3.02 Equipment Hot mix asphaltic concrete plants that produce mix for Department use are governed by Quality Assurance for HotMix Asphaltic Concrete Plants in Georgia, Laboratory Standard Operating Procedure No. 27.

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 air infiltration and to maintain an inert atmosphere during storage. Bins not intended as storage bins may be Section 400-Hot Mix Asphaltic Concrete Construction 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. b. Ensure that surge and storage bins can retain a predetermined minimum level of mixture in the bin when the trucks are loaded. c. Ensure that surge and storage systems do not contribute to mix segregation, lumpiness, drain-down, or stiffuess. 4, Controls for Dust Collector Fines Control dust collection as follows: a. When collecting airborne aggregate particles and returning them to the mixture, hwe 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 thatit will not become entrained 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 :f: 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 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 interrupt mixture production if hydrated lime introduction failsto meet the required target value after no longer than 60 seconds. 6. Net Weight 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 printed total net weight and that obtained from the commercial scales is no greater than 4 lbsll ,000 Ibs (4 kglMg) 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 and certifY the accuracy of the printer. · While the printer system is out of tolerance 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 atthe plant site to check batching scale accuracy. Ensure that plant scales that are used only to proportion mixture ingredients, not to determine pay quantities, are within two percent throughout the range. C. Equipment at Project Site I. Cleaning Equipment Provide sufficient hand tools and power equipment to clean the roadway surface before placing the bituminous tack coat. Use power equipment that complies with Subsection 424.3.02.F. "Power Broom and Power Blower." 2. Pressure Distributor Section 400-Hot Mix Asphaltic Concrete Construction To apply the bituminous tack coat. use a pressure distributor that complies with Subsection 424.3.02.B, "Pressure Distributor." 3. Bituminous Pavers To place hot mix asphaltic concrete, use bituminous pavers that can spread and finish courses that are: · 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 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 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 slope within :f: 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 serning · 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 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 tmdem, 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 contol, or slope control requirements, or both. e. Paver Screed Extension. When the laydown width requires a paver screed extension, use bolt-on 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 extensions 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 fmal compaction on the fmal surface course. Use an approved mechanical device that will: · Apply compactive effort to the asphalt mixture to eliminate objectionable voids as the mixture passes through the wedge device · Produce a wedge with a uniform texture, sh<pe, 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 Section 400-Hot Mix Asphaltic Concrete Construction 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 condition is subject to the Engineer's approval. 400.3.03 Preparation A.

A. Observe Composition of Mixtures I. Calibration of plant equipment If the material changes, or if a component affecting the ingredient proportions has been repaired, replaced, or adjusted, check and recalibrate the proportions. Calibrate as follows: a. . Before producing mixture for the Project, calibrate by scale weight the electronic sensors or settings for proportioning mixture ingredients. b. Calibrate ingredient proportioning for all rates of production. 2, Mixture control Compose hot mix asphaltic concrete from a uniform mixture of aggregates, bitum:iJous material, and if required, hydrated lime, mineral filler, or other approved additive. Make the constituents proportional to produce mixtures that meet the requirements inSection 828. The general composition limits prescribed are extreme ranges within which the job mix formula must be established. Base mixtures on a design analysis that meets the requirements of Section 828. Ensure that the field performance of the in-place mixtures meet the requirements of Section 828.2.B for Permeability, Moisture Susceptibility, Rutting Susceptibility and Fatigue. The in-place mixtures will be subject to te:;ting for compliance with requirements of Section 8282.B under the following conditims: · Deviates greater than 10 percent on gradation on the mixture control sieves from the approved job mix formula based on acceptance or assurance samples. · Deviates greater than 0.7 percent in asphalt content from the job mix formula based on acceptance or assurance samples. · The calculated mean pavement air voids result in an adjusted pay factor greater than 0.80 or any single sub-lot results in mean pavement air voids exceeding] 0:5 %. · Mix produced using an unapproved mix design or job mix formula. Remove and replace (atthe Contractor's expense) any areas determined to not meet the requirements of Section 828.2.B If control test results show that the characteristic tested does not conform to the job mix formula control tolerances given in Section 828, take immediate action to ensure that the quality control methods are effective. Control the materials to ensure that extreme variatims do not occur. Maintain the gradation within the composition limits in Section 828. B. Prepare Bituminous Material Uniformly heat the bituminous material to the temperature specified in the job mix formula with a tolerance of:f: 20 OF (:f: 10 oe). C. Prepare the Aggregate Prepare the aggregate as follows: I. Heat the aggregate for the mixture, and ensure a mix temperature within the linits of the job mix formula. Section 400-Hot Mix Asphaltic Concrete Construction 2. Do not contaminate the aggregate with fuel during heating. 3. Reduce the absorbed moisture in the aggregate until the asphalt does not separate from the aggregate in the prepared mixture. If this problem occurs, the Engineer will e;tablish a maximum limit for moisture content in the aggregates. When this limit is established, maintain the moisture content below this limit. D. Prepare the Mixture Proportion the mixture ingredients as necessary to meet the required job mix formula. Mx until a homogenous mixture is produced. 1. Add Hydrated Lime When hydrated lime is included in the mixture, add it at a rate specified inSection 828 and the job mix formula. Use methods and equipment for adding hydrated lime according to Subsection 400.3.02.8.6, "Hydrated Lime Treatment System." Add hydrated lime to the aggregate by using Method A or B a; follows: Method A-Dry Fonn-Add hydrated lime in its dry form to the mixture as follows, according to the type of plant: a. Batch Type Asphalt Plant: Add hydrated lime to the mixture in the weigh hopper or as approved and directed by the Engineer. b. Continuous Plant Using Pugmill Mixer: Feed hydrated lime into the hot aggregate before it is introduced into the mixer so that dry mixing is complete before the bituminous material is added. c. Continuous Plant Using Drier-Drum Mixer: Add hydrated lime so that the litre will not become entrained into the air stream ofthe drier and so that thorough dry mixing will be complete before the bituminous material is added. Method B-Lime/Water Slurry-Add the required quantityofhydrated lime (based on dry weight) in lime/water slurry form to the aggregate. This solution consists ofIime and water in concentrations as directed by the Engineer. Equip the plant to blend and maintain the hydrated lime in suspension and to mix it with the aggregates uniformly in the proportions specified. 2. Add Gilsonite Modifier When required, add the Gilsonite modifier to the mixture ata rate such that eight percent by weight of the asphalt cement is replaced by Gilsonite. Use either PG 64-22 or PG 67-22 asphalt cement as specified in Subsection 820.2.01. Provide suitable means to calibrate and check the rate ofGilsonite being added. Introduce Gilsonite modifier by either of the following methods. a. For batch type plants, incorporate Gilsonite into the pugmill at the beginning of the dry mixing cycle. Increase the dry mix cycle by a minimum of 10 seconds after the Gilsonite is added and prior to introduction of the asphalt cement. For this method, supply Gilsonic in plastic bags to protect the material during shipment and handling and store the modifier in a waterproof environment. The bags shall be capable of being completely melted and uniformly blended into the combined mixture. Gilsonite may also be added through a mineral filler supply system as described in Subsection 400.3.02.B.5, "Mineral Filler Supply System." The system shall be capable of injecting the modifier into the weigh hopper near the center of the aggregate batching cycle so the material can be accurately weighed. b. For drum drier plants, add Gilsonite through the recycle ring or through an acceptable means which will introduce the Gilsonite prior to the asphalt cement injection point. The modifier shall be proportimately fed into the drum mixer at the required rate by a proportioning device which shall be accurate within:t 10 percent of the amount required, The entry point shall be away from flames and ensure the Gilsonite will not be caught up in the air stream and exhaust system. 3. Materials from Different Sources Do not use mixtures prepared from aggregates from different sources intermittently. This will cause the color of the [mished pavement to vary. E. Observe Weather Limitations Do not mix and place asphaltic concrete if the existing surface is wet or frozen. Follow the temperature guidelines in the following table: r Section 400-Hot Mix Asphaltic Concrete Construction Table 4-Lift Thickness Table Lift Thickness Minimum Temperature '1 in (25 mm) or less 1.1 to 2 in (26 mm to 50 mm) 2.1 to 3 in (51 mm to 75 mm) 3.1 to 4 in (76 mm to 100 mm) 4.1 to 8 in (101 mm to 200 mm) 55 of (13 oc) 45 of (8 OC) 40 of (4 oc) 35 of (2 oc) 32 of (0 .C) and rising.

Place 9.5 mm Superpave and 12.5 mm Superpave up to 4 in (100 mm) thick for driveway and side road transition. 2. Unload the mixture into the paver hopper or into a device designed to receive the mixture from delivery vehicles. 3, Except for leveling courses, spread the mixture to the loose depth for the compacted thickness or the spread rate. Use a mechanical spreader true to the line, grade, and cross section specified. 4. For leveling courses, use a motor grader equipped with a spreader box and smooth tires to spread the material or use a mechanical spreader meeting the requirements in Subsection 400.3.02.C, "Equipment at Project Site." 5. Obtain the Engineer's approval for the sequence of paving operations, including paving the adjoining lanes. Minimize tracking tack onto surrounding surfaces. 6. Ensure that the outside edges ofthe pavement being laid tre aligned and parallel to the roadway center line. 7. For New Construction or Resurfacing Contracts that contain multiple lifts or courses, arrange the width of the individual lifts so that the longitudinal joints of each successive lift are offset from theprevious lift at least 1 ft (300 mm). This requirement does not apply to the lift immediately over thin lift leveling courses. Ensure that the longitudinal joint(s) in the surface course and the mix immediately underneath asphaltic concrete OGFC or PEM are at the lane line(s). NOTE: Perform night work with artificial light provided by the Contractor and approved by the Engineer. 8. Where mechanical equipment cannot be used, spread and rake the mixture by hand. Obtain the Engineer's approval of the operation sequence, including compactive methods, in these areas. 9. Keep small hand raking tools clean and free from asphalt build up. Do not use fuel oil or other harmful solvents to clean tools during the work. 10. Do not use mixture with any of these characteristics: Section 400-Hot Mix Asphaltic Concrete Construction · Segregated · Nonconforming temperature · Deficient or excessive asphalt cement content · Otherwise unsuitable to place on the roadway in the work I I. Remove and replace mixture placed on the roadway that the Engineer determines has unacceptable blemish levels from segregation, streaking, pulling and tearing, or other characteristics. Replace with acceptable mixture at the Contractor's expense. Do not continually place mixtures with deficiencies. Do not place subsequent course lifts over another lift or courses placed on the same day while the temperature of the previously placed mix is 140 OF (60 oC) or greater. 12. Obtain the Engineer's approval of the material compaction equipment. Perform the rolling as follows: a. Begin the rolling as close behind the spreader as possible without causing excessive distortion of the asphaltic concrete surface. b. Continue rolling until roller marks are no longer visible. c. Use pneumatic-tired rollers with breakdown rollers on all courses except asphaltic concrete OGFC, PEM and SMA or other mixes designated by the Engineer. 13. If applicable, taper or "feather" asphaltic concrete from full depth to a depth no greater than 0.5 in (13 mm) along curbs, gutters, raised pavement edges, and areas where drainage characteristics of the road must be retained.The Engineer will determine the location and extent of tapering. G. Maintain Continuity of Operations Coordinate plant production, transportation, and paving operations to maintain a continuous operation. If the spreading operations are interrupted, construct a transverse joint if the mixture immediately behind the paver screed cools to less than 250 OF (120 oC). H. Construct the Joints 1. Construct Transverse Joints a. Construct transverse joints to facilitate full depth exposure of the course before resuming phcement of the affected course. b. Properly clean and tack the vertical face of the transverse joint before placing additional material. NOTE: Never burn or heat the joint by applying fuel oil or other volatile material~. c. Straightedge transverse joints immediately after forming the joint. d. Immediately correct any irregularity that exceeds 3/16 in. in 10 ft (5 mm in 3 m). 2. Construct Longitudinal Joints Clean and tack the vertical face of the longitudinal joint before placing adjoining material. Construct longittdinal joints so that the joint is smooth, well sealed, and bonded. I. Protect the Pavement Protect sections of the newly finished pavement from traffic until the traffic will not mar the surface or alter the surface texture. If directed by the Engineer, ure artificial methods to cool the newly finished pavement to open the pavement to traffic more quickly. J. Modify the Job Mix Formula Ifthe Engineer determines that undesirable mixture or mat characteristics are being obtained, the job mix formula may require immediate adjustment. 400.3.06 Quality Acceptance A. Acceptance Plans for Gradation and Asphalt Cement Content The Contractor will randomly sample and test mixtures on a lot basis. The Department willmonitor the Contractor testing program and perfonn comparison and quality assurance testing. I. Determine Lot Amount Section 400-Hot Mix Asphaltic Concrete Construction A lot consists of the tons (megagrams) of asphaltic concrete produced and placed each production day. If this production is less than 500 tons (500 Mg), or its square yard (meter) equivalent, Jroduction may be incorporated into the next working day. The Engineer may tenninate a lot when a pay adjustment is imminent if a plant or materials adjustment resulting in a probable correction has been made. Tenninate all open lots at the end of the mont:4 except for materials produced and placed during the adjustment period. If the final day's production does not constitute a lot, the production may be included in the lot for the previous day's run; or, the Engineer may treat the production as a separate lot with a corresponding lower number of tests. 2. Detennine Lot Acceptance If the Engineer detennines that the material is not acceptable to leave in place, the materials shall be removed and replaced at the Contractor's expense. 3.

(b) If referee 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 detennine if a thorough investigation is needed. b) Quality Assurance Sampling and Testing Section 400-Hot Mix Asphaltic Concrete Construction (1) Randomly take a minimum of two quality assurance samples from the lesser of five days or five lots of production regardless of mix type or number of projects. (2) Compare test deviation from job mix fonnula to Mixture Control Tolerances inSection 828. If results are outside these tolerances, another sample from the respective mix may be taken. NOTE: For leveling courses less than 110 Ib/yd2 (60 kglm2) 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 lot as in Subsection 400.3.06.A.3.b.3 and use these test results for acceptance and in calculations for the monthly plant rating. Detennine if the Contractor's quality control program is satisfactory and require prompt corrective action by the Contractor if specification requirements are not being met. · Detennine if the QCT has not followed Departmental procedures or has provided erroneous infonnation. B. Compaction Dctennine the mixture compaction using eitherGDT 39 or GDT 59. The compaction is accepted in lots defmed in Subsection 400.3.06. A "Acceptance Plans for Gradation and Asphalt Cement Content" and is within the same lot boundaries as the mixture acceptance. 1. Calculate Pavement Mean Air Voids The Department will calculate the pavement air voids placed within each lot as follows: a. One test per sub-lot. · Lots ~ 500 tons of mix should be divided into 5 sub-lots of equal distance. · Lots < 500 tons of mix should be comprised ofa sub-lot or sub-lots consisting of up to 100 tons of mix each. There may be less than 5 sub-lots. b. A verage the results of all tests run on randomly selected sites in that lot. c. Select the'random sites usingGDT 73. Density tests are not required for asphaltic concrete placed at 125 Ibs/yd2 (68 kglm2) 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 perfonned on tumCouts and driveways. The targeted maximum Pavement Mean Air V oidcontent for all Superpave mixtures is 5.0 percent. Ensure that the maximum Pavement Mean Air Voids for all Superpave mixtures does not exceed 78 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 wiK yield no more than the specified maximum allowed Mean Air Voids. If the contractor needs to adjust the mixture to improve density results, a change in the job mix fonnula may be requested for approval during the adjustment period so long as the followirg values are not exceeded: · Coarse pay sieve :t 4% · No.8 (2.36 mm) sieve :t 2% · No. 200 (75 11m) sieve :t 1% · Asphalt Content :t 0.2% · All value changes must still be within specification limits · Take samples of any in-place mixture represented by unacceptable QCT tests and use the additional sample results for acceptance and,in calculations for the monthly plant rating. The ContractorQCT tests will not be included in the monthly plant rating. Sect50n 400-Hot Mix Asphaltic Concrete Construction If the Office of Materials and Research is satisfied that the contracbr has exerted the maximum compactive effort and is not able to maintain Pavement Mean Air Voids at no more than 78%, the Engineer may establish a maximum target for Pavement Mean Air Voids, If the Pavement Mean Air V oids within a Lot exceeds 7 .8 (or 100% of the maximum larget 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 restated 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 requiremem. 2. Obtain Uniform Compaction For a lot to be accepted for compaction, the air void range cannot exceed 4 percentfor new construction or 5 percent for resurfacing projects. The range is the difference between the highest and lowest acceptance test resuts 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. Visual and Straightedge Inspection Paving is subject to visual and straightedge inspection during and after construction operations until Final Acceptance. Locate surface irregularities as follows: a. Keep a lOft (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 irregularities that exceed 3!l6 in. in 10 ft (5 mm in 3 m) for base and intermediate courses, and 1/8 in. in lOft (3 mm in 3 m) for surface courses. Mixture or operating techniques will be stopped if irregularities such as rippling, tearing, or pulling oCClr 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 wiII 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, bading, 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 finished mat, the Departm61t will take actions based on the degree of segregation. The actions are described below. I. Unquestionably Unacceptable Segregation When the Engineer determines 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 the in-place mat as follows: · Perform extraction and gradation analysis by taking6 in (I50 mm) cores from typical, visually unacceptable segregated areas. · Determine the 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. Section 400-Hot Mix Asphaltic Concrete Construction 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 hat corrective actions were not adequate, follow the measures above beginning with step I.a. above. If the problem'is solved, Work may continue. 2. Unacceptable Segregation Suspected When the Engineer observes segregation in the [mished mat and suspects thatit 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 DepartmeJt 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 inSection 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 400.5.0 I.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 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 theEngineer. Surface tolerance requirements apply to the corrected areas for both subsurface and surface mixes. 400.3.07 Contractor Warranty and Maintenance A. Contractor's Record Maintain a dated, written record of the most recent plant calibration. Keep this record available for the Engineer's inspection at all times. Maintain records in the form of: · Graphs · Tables · Charts · Mechanically prepared data 400.4 Measurement Thickness and spread rate tolerances for the various mixtures are specified in Subsection 400.4.A.2.b, Table I I, Thickness and Spread Rate Tolerance at Any Given Location.
