James G. Speight PhD, DSC, in Asphalt Materials Science and Technology, 2016 10.7.1 Asphalt Cement Binder. In an asphalt cement storage tank, the binder is stored in bulk and usually is circulated continuously by a pump. During this time, the occurrence of aging and hardening should be minimal. However, in the laboratory, the asphalt cement can be heated in an oven for various periods of time ...

In 1934 Barber-Greene introduced the Model 79 asphalt laydown machine, a self-propelled formless laydown machine with a floating screed (Tunnicliff, Beaty and Holt, 1974 [1]).Since then, the basic concept of the asphalt paver has remained relatively unchanged: HMA is loaded in the front, carried to the rear by a set of flight feeders (conveyor belts), spread out by a set of augers, then ...

If the granular base material has a gradation that is somewhat porous, placing a prime coat can often be affected by placing a slow-setting emulsion (SS-1, SS-1 h, CSS-1, CSS-1 h) diluted 5 parts water to 1 part emulsion. By applying several (4 or 5) light applications (0.10 gal/sy), a waterproof surface can be obtained on the base course.

Roller. Two kinds of roller materials are usually used, 65Mn and 9Cr2Mo. The 65Mn roller is a kind of steel castings material with low cost and the 9Cr2Mo roller is high chromium alloy material which cost more but with higher wear resistance. All of the two rollers are treated with our special heat treatment to make it with high wear resistance.
