摘　　要：介绍了以现场钻芯试件观察沥青混凝土历年加铺厚度与其各层破坏情况,并分析了各层加铺材料性质;同时,以DCP试验值量测下基层及路基土壤强度作为评估道路破坏是否由下基层所致。从旧有路面钻芯试件探讨了沥青混凝土加铺质量,以提供工程界路面维护的参考。The purpose of the study is to introduce the paving thickness of the asphalt concrete in the past years and its damage in different layers based on the site core specimen,and this paper analyzes the paving material properties in every layer. At the same time,the strength of the lower base course and subgrade soil by DCP test is used to evaluate the road damage condition caused by the lower base course.This paper analyzes the paving quality of asphalt concrete pavement by core specimens of the old road pavement,which provides road maintenance reference.
