市政道路沥青层透水性研究

Study on permeability of municipal road asphalt layer

透水沥青结构层能够保证路面积水顺利通过各层渗透到地基土中,实现水资源的循环利用,以省内市政道路沥青透水层施工项目为例,分析了透水沥青路面的结构体系及内部排水结构,对该项目设计方案的承载能力影响因素进行对比分析,论证了项目设计方案的可行性。

Pervious asphalt structure layer can ensure that pavement water seeps into foundation soil smoothly through all layers to realize the recycling of water resources. Taking the municipal road asphalt permeable layer construction project in Henan Province as an example,this paper analyses the structure system and internal drainage structure of pervious asphalt pavement,compares and analyses the influencing factors of bearing capacity of the project design,and demonstrates the feasibility of the project design scheme.
