Evaluation of the Particulate Additive Test
Primary Topic: Materials-Asphalt
Description: The objective of this study was to acquire and/or develop commercially available equipment for conducting the Particle Additive Test (PAT) and Laboratory Stability Test (LAST). These tests were developed under the National Cooperative Highway Research Program (NCHRP) Project 9-10 entitled "Protocols for Modified Asphalt Binders." This study evaluated the established protocols and explored methods for improving the tests. Based on the results, recommendations were presented to the Superpave® Binder Expert Task Group regarding the utility of these tests. Results from the LAST are published in FHWA-HRT 04-111, Evaluation of Laboratory Asphalt Stability Test.
