摘　　要：通过对几种常见基质沥青、SBS和PE改性沥青各项性能指标,及其拌制的沥青混合料高、低温性能(抗压强度、车辙、单轴压缩蠕变、低温弯曲、J积分试验等)的测试和相关性分析,探讨了重交通道路石油沥青路用性能的合理评价指标,为选用优良的道路沥青提供了参考依据。By the tests on performances of several types of common-used asphalts and asphalt con crete under high temperature or low temperature, It was revealed that the relativity of asphalt and asphalt concrete performance. Besides, it was recommended that several rational evaluate index for the asphalt performance on the basis of comparative analysis, which provides reference to select excellent asphalt.
