煤矿产区公路交通特征及路面类型研究

The Research on Highway Traffic Characteristics and Pavement Types in Coal Mining Area

煤矿产区公路路面状况对煤矿资源的开发利用具有重要影响,而抢修材料的开发和选取是道路养护工作中的关键之一。为了保证煤矿产区公路的正常通车,减轻路面病害对矿产资源运输的不利影响,结合矿区公路的交通特征,提出了AC型混合料、SMA混合料、AR-AC混合料这3种可用作煤矿产区路面抢修的混合料类型,并对其技术经济性能进行了简要的对比分析;然后以山西某矿区公路为例,介绍了抢修材料的工程应用效果,以期为矿区公路路面的养护管理工作提供参考。

Combined with the highway traffic characteristics in coal mining area,this paper proposed AC mixture,SMA mixture and AR-AC mixture,these three kinds of mixture could be used as the pavement repair mixture types in coal mining area. It briefly compared and analyzed its technical and economic performance. For a coal mining area highway in Shanxi,it also introduced the engineering application effect of the repair materials, provided reference for the pavement maintenance management in the coal mining area.
