摘要
首先对公交停靠站沥青路面的病害进行调查,调查显示,此类易损路段病害主要表现为裂缝、拥包、坑槽、车辙等。然后对病害产生原因以及路面破坏机理进行分析,路面结构、材料性能以及防水特性很大程度决定着路面寿命。最后,根据重庆某实体工程,对已损坏的公交停靠站路面结构进行优化设计,采用抗车辙性能较好的沥青混合料进行修复处治。
Firstly, we investigated the diseases of asphalt pavement at the bus bays. The survey showed ： The main diseases were fissures, convexes, pits, rutting and so on. Then, we analyzed the cause of the disease as well as pavement failure mechanism. The pavement structure, material properties and waterproof characteristics determined the life of pavement. Finally, we used Chongqing physical works to optimize the design of the damaged bus bay pavement structure and used better resistance asphah mixture to repair the road.
