摘　　要：当前城市道路大多数采用硬化铺装,一旦雨水过大,容易造成城市内涝,为了解决这个问题,本文设计了生态型城市透水沥青路面结构,路面结构包括面层、基层、垫层、路基,并对路面的饱水率进行实验测定,模拟降水过程对路面结构的渗水效能进行评价,结果表明:3组试件的饱水率分别为2.11、2.09、2.14,路面结构实际水位最高为426.478mm,低于路面结构厚度500mm,表明在整个降雨过程中不会出现路面的积水现象。At present, most urban roads adopt hardened pavement,once the rainfall is too large,it is easy to cause urban waterlogging.In order to solve this problem,this paper designs an ecological urban pervious asphalt pavement structure,the pavement structure includes surface layer,base course,cushion and subgrade, and tests the water saturation rate of the pavement,and evaluates the water seepage efficiency of the pavement structure by simulating the precipitation process.The results show that:the water saturation rates of the three groups of specimens are 2.11,2.09 and 2.14 respectively.The highest actual water level of pavement structure is 426.478 mm,which is 500 mm lower than the thickness of pavement structure,which indicates that there will be no ponding in the whole rainfall process.
