Standard Practice for Determining Asphalt Volume

31 Asphalts change in volume with change in temperature They are loaded or transferred at widely varying temperatur Volume correction factors are used to adjust bulk volumes measured at those temperatures to corresponding volumes at a base temperature of 15°C or [60°F] for the purposes of custody transfer and accounting operations.

Tack Coats

The tack coat application vehicle should be able to compensate for this Excessively low spray bars result in streaks, while excessively high spray bars cause excessive nozzle overlap resulting in an excessive application rate Pressure within the distributor must be capable of forcing the tack coat material out the spray nozzles at a constant.
