高速公路路基路面早期水损害在高等级公路中较为普遍,类型也较多,已成为影响公路正常运营的问题之一。为解决由于排水不良造成路基、路面强度及稳定性不足的问题,对高速公路路基路面早期水损害现状及类型进行了调查和研究,本文分析了高速公路路基路面水损害机理及其成因,并结合工程实际给出了不同类型水损害的预防与治理措施的建议。
Early water damage of expressway subgrade and pavement is more common in high-grade highways and has more types, which has become one of the problems affecting the normal operation of the highway. In order to solve the problem of lack of strength and stability of roadbed and pavement due to poor drainage, the status quo and types of early water damage of subgrade and pavement of expressway are investigated and studied. The paper analyzes the mechanism and causes of water damage of subgrade and pavement of expressway, Engineering practice gives different types of water damage prevention and control measures for the proposal.
