PREPARING ASPHALT FOR CONSTRUCTION OPERATIONS Paving grade asphalt (asphalt cement), which at normal atmospheric temperatures is semisolid and highly viscous, must be made temporarily fluid (liquefied) for handling during construction operations, such as pumping through pipes, transporting in tanks, spraying through nozzles, and mixing with
Some nozzle type designs incorporate large size (6 mm (0.25 in) or larger) spray nozzles that increase the reliability of spray equipment because they require less liquid filtration and are less likely to clog. Spinner disks can dispense liquid droplets that are too large for uniform coating of the pavement surface.
Equip the mixing machine with a water pressure system and nozzle-type spray bar to provide a water spray ahead of and outside the spreader box when required. Apply water at a rate that will dampen the surface but not create free-flowing water ahead of the spreader box. The mixer shall be equipped with a computerized material monitoring system with
The proper nozzles, nozzle angles, spray bar height, pump speed, and pump pressure are items that are required to be checked. The chip spreader and the pneumatic-tire roller should remain as close to the distributor as possible. The intent of a seal coat operation is to place type of asphalt applied. During cool, damp, cloudy, or humid
