The objective of this study is 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 test were explored. Based on our results, recommendations were presented to the SuperpaveĀ® Binder Expert Task Group regarding the utility of these tests.
Asphalt binders have an inherent ability to reverse damage in the form of micro-cracks that is causeddue to the repeated action of external loads. Thi...
Modifying asphalt binder is one of the primary methods of improving the performance of asphalt mixtures; the benefits include improved rutting resista...
