| 摘 要： | 基于线弹性断裂力学，分析了沥青路面开裂以后，裂缝尖端的应力强度因子与路面温度分布和路面材料特性参数之间的关系，分析结果表明，在沥青路面的抗裂设计中，合理设计沥青面层的厚度和优选温缩性小的路面材料是提高沥青路面抗裂性能的两个重要方面。

| Abstract: | Based on the linear elastic fracture mechanics,the paper analyzes the relationship among the stress intensity factor of the crack tip,the pavement temperature distribution and pavement material parameter after the asphalt pavement cracks,analysis result proves that,in the anti-cracking design of the asphalt pavement,reasonably designing the depth of the asphalt surface and optimal selecting the pavement materials with low temperature shrinkage are the two important aspects to enhance the crack resistance of... |
