Development of Performance-Based Specification for Asphalt Binders: Fatigue Characterization
Project Information
Test pavements were constructed with the primary variable being the binder type. Full-scale rutting and cracking performance were collected and compared to various candidate binder tests to identify the most discriminating element to replace the current specification for asphalt fatigue cracking and rutting.
Goals
The primary objective of this full-scale accelerated pavement testing was to evaluate the performance of unmodified and polymer-modified asphalt binders, and to recommend improved specification tests over existing Superpave (SUperior PERforming Asphalt PAVEments) performance-grading methodologies.
