摘　　要：本文叙述了沥青混凝土徐变的测试方法和设备。研究了沥青混凝土的徐变特性。试验方案中考虑了3个因素,即沥青含量、应力状态和温度。试验结果表明这些因素对沥青混凝土徐变特性有显著影响。沥青混凝土的徐变和加载时间的对数之间有着良好的线性关系。This paper describes the test method and equipment of creep test inf asphalt concrete. The creep behavion of asphalt concrete was studied. Three factors(asphalt content, confining pressure, temperature) were considered in the test program.The results show that the creep behavior of asphalt concrete were singnificantly influenced by these factors. There is a strong linear relationship between creep of asphalt coccrete and log of loading time.
