高速公路路面结构性能大修后评价

Evaluation of highway pavement structure performance after the major rehabilitation

对于无法适应交通量和荷载需求的道路,有必要根据其路面结构状况采取一定的维修措施,并对养护效果进行后评价。以宁波市某高速为依托,对大修前、后的路面结构性能进行对比分析,发现对于不同等级的路面结构,应分别采用单层罩面或双层罩面维修。

For roads that cannot adapt to traffic volume and load requirements,it is necessary to take certain maintenance measures according to the pavement structure condition,and conduct a post-evaluation of the maintenance effect.Based on an expressway in Ningbo city,this paper compares and analyzes the pavement structure performance before and after the major rehabilitation.The results show that for different levels of pavement structures,single-layer or double-layer overlays should be used for maintenance.
