文中介绍一种简单合理的疲劳试验仪器和分析方法。先通过3种循环扭转荷载试验,确定基本线粘弹材料特性和沥青基体的疲劳特性;再利用图片进行破坏分析,发现通常沥青基体试验结果不但与沥青胶结料试验数据一致,且与沥青混凝土疲劳试验结果相吻合。研究发现,这是一种快速、可重复且精确度高的试验方法。 This article describes a simple and reasonable fatigue test equipment and analysis methods. Firstly, three cyclic torsional load tests were carried out to determine the characteristics of the basic viscoelastic material and the fatigue properties of the asphalt matrix. Using the pictures for the damage analysis, it was found that the asphalt matrix test results were not only consistent with the asphalt binder test data but also with the asphalt concrete fatigue The test results match. The study found that this is a fast, repeatable and accurate test method.
