compactive weight in the range of 135 to 200 pounds per linear inch ( PLI), determined as follows: (Any variation of this equipment requirement must be approved by the Engineer.) Establish an appropriate rolling pattern for the pavement in order to effectively seat the mixture without crushing the aggregate. In the event that the roller begins to crush the aggregate, reduce the number of coverages or the PLI of the rollers. If the rollers continue to crush the aggregate, use a tandem steel -wheel roller weighing not more than 135 PLI of drum width.
337-7.5 Temperature Requireme nts for FC -9.5 and FC -12.5:

thickness as shown in the Contract Documents. For construction purposes, the plan thickness will be converted to spread rate as defined in 334 -1.4. Plan quantities are based on a G mm of 2.540, corre sponding to a spread rate of 110 lb/yd2-in. Pay quantities will be based on the actual maximum specific gravity of the mix being used.
337-8.2 FC-5: The total thickness of the FC -5 layer will be the plan thickness as shown

For c onstruction purposes, the plan thickness will be converted to spread rate based on the combined aggregate bulk specific gravity of the asphalt mix being used as shown in the following equation: Spread rate ( lb/yd2) = t x G sb x 40.5 Where: t = Thickness (in.) (Plan thickness) Gsb = Combined aggregate bulk specific gravity from the verified mix design The weight of the mixture shall be determined as provided in 320 -3.2.

Pay quantities will be based on the actual combined aggregate bulk specific gravity (G sb) of the mix being used.
337-9 Special Equipment Requirements for FC -5.
337-9.1 Fiber Supply System: Use a separate feed system to accurately proportion the
required quantity of fibers into the mixture in such a manner that uniform distribution is obtained. Interlock the proportioning device with the aggregate feed or weigh system to maintain the correct proporti ons for all rates of production and batch sizes. Control the proportion of fibers to within plus or minus 10% of the amount of fibers required. Provide flow indicators or sensing devices for the fiber system, interlocked with plant controls so that an alarm will be activated if introduction of the fiber fails. Stop production of the asphalt mixture and resume production once the fiber supply system is operating correctly. When a batch plant is used, add the fiber to the aggregate in the weigh hopper or as approved and directed by the Engineer. Increase the ba tch dry mixing time by 8 to 12 seconds, or as directed by the Engineer, from the time the aggregate is completely emptied into the pugmill. Ensure that the fibers are uniformly distributed prior to the addition of asphalt binder into the pugmill. When a drum-mix plant is used, add and uniformly disperse the fiber with the aggregate prior to the addition of the asphalt binder. Add the fiber in such a manner that it will not become entrained in the exhaust system of the drier or plant.
337-9.2 Hydrated Lim e Supply System: For FC-5 mixes containing granite, use a
separate feed system to accurately proportion the required quantity of hydrated lime into the mixture in such a manner that uniform coating of the aggregate is obtained prior to the addition of the asphalt binder. Add the hydrated lime in such a manner that it will not become entrained in the exhaust system of the drier or plant. Interlock the proportioning device with the aggregate feed or weigh system to maintain the correct proportions for all rat es of production and batch sizes and to ensure that all mixture produced is properly treated with hydrated lime. Control the proportion of hydrated lime to within plus or minus 10% of the amount of hydrated lime FY 2023-24 Return to Table of Contents required. Provide flow indicators or sensing devices for the hydrated lime system , interlocked with plant controls so that an alarm will be activated if introduction of the hydrated lime fails. Stop production of the asphalt mixture and resume production once the hydrated lime supply system is oper ating correctly. The addition of the hydrated lime to the aggregate may be accomplished by Method A or B as follows:
337-9.2 1 Method A - Dry Form: Add hydrated lime in a dry form to the mixture
according to the type of asphalt plant being used. When a batch plant is used, add the hydrated lime to the aggregate in the weigh hopper or as approved and directed by the Engineer. Increase the batch dry mixing time by eight to twelve seconds, or as directed by the Engineer, from the time the aggregate is completely emptied into the pugmill. Uniformly distribute the hydrated lime prior to the addition of asphalt binder into the pugmill. When a drum -mix plant is used, add and uniformly disperse the hydrated lime to the aggregate prior to the addition of the asphalt binder. Add the hydrated lime in such a manner that it will not become entrained in the exhaust system of the drier or plant.
337-9.2 2 Method B - Hydrated Lime/Water Slurry: Add the required quantity
of hydrated lime (based on dry weight) in a h ydrated lime/water slurry form to the aggregate. Provide a solution consisting of hydrated lime and water in concentrations as directed by the Engineer. Use a plant equipped to blend and maintain the hydrated lime in suspension and to mix it with the aggre gates uniformly in the proportions specified.
337-9.3 Hydrated Lime Pretreatment: For FC-5 mixes containing granite, as an
alternative to 337 -9.2, pretreat the aggregate with hydrated lime prior to incorporating the aggregate into the mixture. Use a feed system to accurately proportion the aggregate and required quantity of hydrated lime, and mix them in such a manner that uniform coating of the aggregate is obtained. Control the proportion of hydrated lime to within plus or minus 10% of the amount require d. Aggregate pretreated with hydrated lime in this manner shall be incorporated into the asphalt mixture within 45 days of pretreatment.
337-9.3 1 Hydrated Lime Pretreatment Methods: Pretreat the aggregate using
one of the following two methods: Pretreatment Method A - Dry Form: Add the required quantity of hydrated lime in a dry form to the aggregate. Assure that the aggregate at the time of pretreatment contains a minimum of 3% moisture over saturated surface dry (SSD) conditions. Utilize equipment to accurately proportion the aggregate and hydrated lime and mix them in such a manner as to provide a uniform coating. Pretreatment Method B - Hydrated Lime/Water Slurry: Add the required quantity of hydrated lime (based on dry weight) in a hydrated lime/water slurry form to the aggregate. Provide a solution consisting of hydrated lime and water in a concentration to provide effective treatment. Use equipment to blend and maintain the hydrated lime in suspension, to accurately proportion the aggregate and hydrated lime/water slurry , and to mix them to provide a uniform coating.
337-9.3 2 Blending QC Records: Maintain adequate QC records for the
Engineer’s review for all pretreatment activities. Include as a minimum the following information (for each batch or day’s run of pretreat ment): pretreatment date, aggregate certification information, certified test results for the hydrated lime, aggregate moisture content prior to blending, as -blended quantities of aggregate and hydrated lime, project number, customer name, and shipping dat e. FY 2023-24 Return to Table of Contents

337-11 Method of Measurement.
For the work specified under this Section (including the pertinent provisions of Sections 320 and 330), the quantity to be paid for will be the weight of the mixture, in tons. For each pay item, the pay quantity will be based on the quantity placed on the project, limited to 110% of the adjusted plan quantity for the pay item . For dense -graded mixes, the adjusted plan quantity will be determined by dividing the pay item’s original plan quantity (including any Engineer approved quantity revisions) by the design G mm stated in 334 -1.4, then multiplying it by the tonnage -weighted average G mm of the mixes used for the pay item. For open graded mixes, the adjusted plan quantity will be determined by dividing the pay item’s original plan quantity (including any Engineer approved quantity revisions) by the design G sb stated in
337-8 2, then multiplying it by the tonnage -weighted average G sb of the mixes used for the pay
item. The bid price for the asphalt mix will include the cost of the asphalt binder (asphalt rubber (or polymer), asphalt cement, ground tire rubber, anti -stripping additive, blending and handling) and the tack coat application as directed in 300 -8, as well as fiber stabilizing additive and hydrated lime (if required). There will be no separate payment or unit price adjustment for the asphalt binder material in the aspha lt mix. The weight will be determined as provided in
