Evaluation of the Particulate Additive Test

Research/Reference: useful for researchers doing further work in the pavement area as well as those developing improved testing and design procedures. Includes documents of historical value.

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.
