Abstract
Asphalt mastic is known to play an important role when determining the fatigue performance of asphalt mixture. Time sweep test using a Dynamic Shear Rheometer can be used. However, a long testing time is a major disadvantage, and no guidelines for testing asphalt mastic are available. Therefore, this study presents an Accelerated Dynamic Shear Rheometer Fatigue Test (ADFT) for fatigue testing of asphalt binders and mastics. Asphalt binder of the types 50/70 and 25/55-55 A, and corresponding asphalt mastics were tested. The results were analysed in regard to consistency of test results, efficiency of testing time, and repeatability. ADFT showed better applicability than conventional time sweep test, and ADFT reduced testing time significantly. Repeatability was improved.
