Investigation of cement concrete pavement diseases of a national trunk highway and analysis of influencing factors

以国道G205线蕉岭段为例,通过对该段水泥路面病害情况展开调查,分析水泥路面破坏的典型病害类型及特点,确定重载交通条件、路面设计不足和养护施工过程中的不规范是病害产生的主要原因,提出防止水泥混凝土路面在汽车重载作用下发生早期破坏的措施。

This paper takes the Jiaoling section of national highway G205 as an example,and analyzes the typical disease types and characteristics of cement pavement damage by investigating the cement pavement disease in this section.It is determined that heavy traffic conditions,inadequate pavement design and irregularities in the maintenance and construction process are the main causes of the disease.Finally,measures to prevent the early damage of cement concrete pavement under heavy vehicle load are proposed.
