Book Description
The purpose of this Circular is to familiarize the asphalt user with the source of asphalt, the variable chemistry of asphalt, why variable performance should be expected when asphalt is used in roadways and what is currently missing from the specification process. Several areas are identified where refinements in the specification process would improve the ability to classify asphalts by their expected performance. This Circular summarizes more than 2,500 pages written during the past 20 years on the effects of fundamental chemistry on the rheological properties of asphalt. This Circular should be especially useful to civil engineering students who intend to work in some highway construction-related business.
