分析了重载交通路段的交通状况和运维特点,总结了车辆荷载对道路路面的作用机理,包括弯曲、疲劳、剪切和车辙效应。分析了我国规范对于重载交通路段设计的不适宜性,从而提出针对重载交通路面的设计方法,首先需要确定临界作用荷载,并进行轴载换算等效,最后基于长寿命路面设计思路进行沥青路面设计,这样能够满足重载交通路段路面的运营使用寿命。
The traffic conditions and operation and maintenance features of heavy traffic sections are analyzed. The mechanism of vehicle load on the road surface is summarized, including bending, fatigue, shearing and rutting effects. This paper analyzes the inappropriateness of our country’s norms for the design of heavy traffic road sections, and puts forward the design method for heavy traffic traffic pavement. First, we need to determine the critical load, and carry on axle load conversion equivalent. Finally, based on long life pavement design ideas, Pavement design, so that it can meet the operational life of heavy-duty traffic pavement.
