在对湖北京珠高速公路交通量进行计算和预测的基础上 ,发现超载现象严重 ,平均胎压达 0 .79MPa。换算成轴载后 ,采用电算法设计、分析 ,湖北京珠高速公路北段路面结构合理设计结果为面层厚度16cm,基层厚度 4 0 cm,底基层厚度为 2 0 cm。同时 ,给出了各标段路面设计结果。
On the basis of calculating and forecasting the traffic volume of Beijing-Zhuhai expressway, it is found that the overloading phenomenon is serious with an average tire pressure of 0.79MPa. After conversion into axle load, the design and analysis of the electrical algorithm are adopted. The reasonable design results of the pavement structure of the northern section of Beijing-Zhuhai Expressway are that the surface layer thickness is 16cm, the base layer thickness is 40cm and the base layer thickness is 20cm. At the same time, the design results of each section of pavement are given.
