我国北部地区是我国重工业密集分布区,重载车辆多,超载严重,路面破坏形式尤其自身特征。本文通过对北方某市6条干线公路路面结构、路面超载情况和病害形式进行调查、分析并结合路面结构受力分析,经比对、研究得出病害成因,优选出合理结构进行推荐,以期为重工区路面典型结构提供参考和借鉴。
The northern part of our country is a densely-distributed area of heavy industry in our country. There are many heavy-duty vehicles with serious overloading and pavement damage forms especially their own characteristics. In this paper, the pavement structure, road surface overload conditions and disease forms of 6 trunk roadways in a certain city in the north of China were investigated. After analyzing and analyzing the mechanical analysis of pavement structure, the cause of the disease was found out and the reasonable structure was recommended for recommendation. Heavy industry area pavement typical structure to provide reference and reference.
