Abstract:
The research efforts presented in this TechBrief were designed to advance the deployment of FHWA’s performance testing and evaluation of asphalt pavements. These efforts can be categorized as follows:
• Development of a thermal cracking model.
• Development of Sapp (apparent damage capacity) and the Rutting Strain Index (RSI) as the cracking and rutting indexes, respectively.
• Development of FlexMAT™ version 2.1.
• Development of FlexPAVE™ version 2.0.
• Development of performance-volumetrics relationships (PVRs) and index-volumetrics relationships (IVRs).
• Development of AMPT balanced mix design (BMD) methods.
• Reliability analysis of cracking damage and rut depth predictions.
