| 摘 要： | 由于旧水泥混凝土路面存在接缝和裂缝，在交通荷载、环境因素以及二者共同作用下扩展并延伸到沥青加铺层中，形成反射裂缝。结果破坏路面结构的整体性，影响道路的使用品质，削弱路基的强度和稳定性，导致路面的早期破坏，文中揭示反射裂缝产生的力学机理、寻求防治反射裂缝的最佳措施。

| Abstract: | The seams and cracks in the environmental factors, or both to be expanded and extended into the asphalt overlay, emitter cracks. The results undermine the integrity of the pavement structure, affect the quality of road use, and weaken the strength and stability of the roadbed, resulting in the early destruction of the road. The mechanical mechanism of reflection crack is analyzed in order to seek the countermeasure against the reflection crack. |
