Abstract:
This report documents a Federal Highway Administration (FHWA) research study that was performed to assist the highway community in validating Superpave tests and specifications being used to grade asphalt binders according to their relative rutting resistances. Superpave and other asphalt mixture tests for rutting were also evaluated.
To accomplish the objective, twelve full-scale pavements were constructed at the FHWA Pavement Testing Facility in 1993. This facility is located at the Turner-Fairbank Highway Research Center in McLean, VA. The pavements were tested for rutting resistance by an Accelerated Loading Facility, which applies one-half of a rear truck axle load. The asphalt binder and mixture tests were validated using the results from these pavement tests.
This document will be of interest to personnel involved with Superpave and the evaluation of hot-mix asphalts for rutting performance. Recommendations are given concerning a wide range of tests. Asphalt binder and mixture tests used to measure fatigue cracking resistance were also evaluated in this project. The results will be presented in a future report
