近年来,人们受到经济利益的驱使,大型运输车辆的轴载大幅提高,对公路路面造成极大的损害。为此,必需对运输车辆的轴载与重载交通进行界定,提出各级公路路面的重载与重载交通界限,以便制定相应的重载路面设计方法或采取相应的行政管理措施。通过路面结构应力分析及重载道路交通组成的统计分析方法,提出各级公路水泥混凝土路面的重载与重载交通界限。
In recent years, people are driven by economic interests and the axle load of large transport vehicles has increased greatly, causing great damage to the road surface. Therefore, it is necessary to define the axle load and heavy traffic of transportation vehicles, and to put forward the limits of heavy traffic and heavy traffic of highway pavement at all levels in order to formulate the corresponding design method of heavy load pavement or take the corresponding administrative measures. Based on the stress analysis of pavement structure and the statistical analysis method of heavy traffic, the paper puts forward the traffic heavy and heavy traffic boundaries of cement concrete pavement at all levels.
