Abstract

During the past two years, a cooperative viscosity testing program under the sponsorship of The Asphalt Institute, has been conducted on a range of commercially available asphalt cements. The program was designed (1) to develop an accurate method for viscosity measurement of asphalt cements at 140 F and (2) to compare the consistency characteristics of asphalt cements as measured by a fundamental viscosity test. The results of this program to date are discussed.
