stiffness (high viscosity) asphalt cements should be used for asphalt concrete layers 5 inches and thicker, and the fatigue life of such mixes should be evaluated using constant-stress testing.3 In practice, however, it is not common to modify the mixture stiffness for different asphalt concrete layer thicknesses. Bleeding
Since asphalt cement is a petroleum product, it can be dissolved by many other petroleum-derived products, such as gasoline and car oil. Therefore, in localized areas where extensive fuel spillage is likely, it may be advisable to seal the pavement with a commercially-available proprietary sealer that is impervious to petroleum solvents.
Nov 21, 2017· Specifications. It may be either (1) a completely new special provision or (2) an SSP with added or deleted language not covered by the SSP instructions. It is typically developed by the district. Any pavement related NSSP must be approved by the State Pavement Engineer through the Office of Asphalt Pavements or Office of Concrete Pavements.
The trench should be below the groundwater surface and dug into a lower, more inpervious soil layer to intercept groundwater. The drains may be made of metal, concrete, clay, asbestos-cement, or bituminous fiber and should be 15 centimeters (6 inches) in diameter or larger. (2) Drilled drains.
Asphalt concrete. The usage of these additives in hot mixed asphalt (above) may afford easier compaction and allow cold weather paving or longer hauls. Use of warm mix is rapidly expanding. A survey of US asphalt producers found that nearly 25% of asphalt produced in 2012 was warm mix, a 416% increase since 2009.
