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.

已知沥青胶泥在确定沥青混合物的疲劳性能时起着重要的作用。可以使用使用动态剪切流变仪的时间扫描测试。然而，较长的测试时间是主要的缺点，并且没有用于测试沥青胶泥的指南。因此，本研究提出了一种用于沥青粘合剂和胶泥疲劳测试的加速动态剪切流变仪疲劳测试（ADFT）。测试了类型为50/70和25 / 55-55 A的沥青粘合剂以及相应的沥青胶泥。分析了测试结果的一致性，测试时间的效率和可重复性。与传统的时间扫描测试相比，ADFT显示出更好的适用性，并且ADFT大大减少了测试时间。重复性得到改善。
