摘要
对沥青路面高温力学特性进行了研究,并运用库伦的内摩擦理论对沥青混合料在高温状态下的强度和稳定性进行了分析。通过分析可知粘聚力和内摩阻角是影响沥青混合料高温性能的主要因素,并指出以后研究的重点是通过优化与设计,确定级配和沥青用量来提高沥青混合料的高温性能。
The paper has studied high temperature mechanical properties of asphalt pavement, besides strength and stability of asphalt mixture under high temperature were analyzed through the theory of internal friction of Coulomb. The above analysis shows that the cohesion and internal friction angle is the main factors of high - temperature performance of asphalt mixture, and that future research is focused on optimizing the design to determine the gradation and asphalt content to improve high temperature performance of asphalt mixture.
