EVALUATION OF THE PARTICULATE ADDITIVE TEST

The objective of this study was to acquire and/or develop commercially available equipment for conducting the Particulate Additive Test (PAT) and Laboratory Stability Test (LAST). Dr. Hussein Bahia and his coworkers developed these tests under the National Cooperative Highway Research Program (NCHRP) Project 9-10 entitled "Protocols for Modified Asphalt Binders." In the course of the study, the established protocols were evaluated and methods for improving the tests were explored. The PAT, which is the subject of this report, separates the additive from the asphalt binder and evaluates the volume of this particulate matter. The project evaluated ways to improve the existing test and made a recommendation to the Superpave Binder Expert Task Group regarding the utility of this test.
