重交通条件下高等级公路沥青路面结构设计

Structure Design of High Grade Highway Asphalt Pavement Under Heavy Traffic Conditions

随着国家经济的发展,公路交通运输呈现出"重载、大流量和渠化交通"的特点,交通量、大型货车和超载超重车辆的大幅增长,导致沥青路面受到严重的破坏,采用标准轴载和图式设计重交通路面结构厚度的方法已经不能满足现实需求.从重交通特点出发,对设计指标、参数和结构组合等进行研究,分析了沥青路面设计指标和参数确定的方法,确定了各结构层的厚度,为沥青路面结构设计提供一定的理论及工程参考价值.

With the development of national economy, characteristics, such as heavy load, large flow and channel highway transportation presents a series of traffic. Due to the substantial increasing traffic volumes, heavy duty trucks and heavy-load vehicles, asphalt pavement appears severely damage, thickness design in pavement structure of heavy traffic using standard axle load and graphical representation can not satisfy the reality. Based on the characteristics of heavy traffic, the design indexes, parameters and structure combinations were studied, the determining method of design indexes and parameters of asphalt pavement were analyzed, and the thicknesses of structure layers were determined, which can provide theoretical and engineering reference for structure design of asphalt pavement.
