高速公路路面结构服役状态综合评价体系研究

Research on the Comprehensive Assessment System for Service Performance of Expressway Pavement Structures

摘要:

近年来我国大量高速公路服役年限已接近或达到设计年限，随之带来的养护决策问题日益凸显，对路面结构服役状态进行综合评价变得非常重要。结合溧马高速养护工程，采用三维探地雷达及快速激光弯沉检测车进行道路现场检测，同时结合室内试验方法得到路面材料的关键指标，形成一套结合路面结构完整性及结构强度评价的综合服役状态评价方法，提出相应的评价分级指标阈值及养护决策体系，研究成果在实际工程中得到成功应用，为高速公路养护决策提供了科学指导。

Abstract:

In recent years, a large number of highways in China have reached or exceeded their designed service life. The resulting maintenance decision-making issues have become increasingly prominent, and it has become important to conduct a comprehensive evaluation of the service condition of the pavement structure. In combination with the maintenance project of Li-Ma Expressway, three-dimensional ground-penetrating radar and rapid laser deflection detection vehicles were used for on-site road inspections. At the same time, it combines indoor test methods to obtain key indicators of pavement materials, forming a comprehensive service condition evaluation method that combines the integrity and strength evaluation of the pavement structure. It also proposes corresponding evaluation classification threshold values and maintenance decision-making systems. The research results have been successfully applied in actual engineering, providing scientific guidance for highway maintenance decisions.
