高速公路路面结构内部滞水问题研究

Research on Internal Backwater Matters in Road Surfacing Structure of Expressways

由于降水而形成的路面结构内部滞水是导致我国高等级公路路面早期损坏的重要原因 通过几种类型结构的路面对比试验 ,提出了路面结构中治水的最佳方案是排水加防水措施综合应用 。

Precipitation usually causes internal backwater in road surfacing structures.While internal backwater is a vital reason for early damages of china's advanced highways road surfaing structures.Through comparison tests of various road surfacing structures, this paper brings forward optimum scheme,which combines drainage and waterproofing measures comprehensively,so as to better guarantee the security and durability of road surfacing structures.
