重载交通下分车道管理老路路面改造方案研究

Research on the Reconstruction Scheme of the Old Road with Divided Lane Management under Heavy Load Traffic

以G30连霍高速公路哈密至吐峪沟段改扩建工程为例,通过不同分车道管理后的服务水平和车道数需求进行比较,拟定分车道管理的运营方案,进而明确不同车道的车型分配和轴载作用次数,达到充分利用既有老路的剩余使用寿命目的,避免路面的过度利用或改造不彻底情况。

Taking the reconstruction and expansion project from Hami to Tuyugou section of G30 Lianyungang-Khorgos Expressway as an example,by comparing the service level and lane number demand after different lane division management,the operation plan of lane division management is drawn up,and then the model distribution and the number of axle load functions of different lanes are clarified,so as to make full'use of the remaining life of the existing old road to avoid excessive or incomplete transformation of the road surface.
