重载交通病害分布规律及成因分析

根据气候条件、结构形式和交通组成特性,选取京沪高速具有代表性的重载路段,进行病害统计,分析病害所占比重选取具有代表性的典型病害,为分析得出重载交通条件下病害的发展规律及其成因,从重载交通、路面结构、环境条件、养护措施方面进行讨论。在此基础上,为重载交通沥青混合料设计和路面结构设计提供一定的参考依据。

Distribution Law and Cause Analysis of Heavy Traffic Diseases

According to the climate conditions,structural forms and traffic composition characteristics,this paper selects the representative heavy-duty sections of Beijing Shanghai Expressway,carries out disease statistics,analyzes the proportion of disease,selects the representative typical disease,and analyzes the development law and causes of disease under heavy-duty traffic conditions from the aspects of heavy-duty traffic,pavement structure,environmental conditions and maintenance measures.On this basis,it provides some reference for the design of heavy traffic asphalt mixture and pavement structure.
