改扩建道路路面评估体系

通过对天津市滨海新区几条有代表性的干线道路的路面结构及交通组成的调查,确定该区域代表车型及荷载分布范围,同时通过力学计算,明确路面结构对轴载变化最敏感的范围,最后讨论了轴载变化对轴次换算、弯沉等路面设计指标的影响,确定了天津市滨海新区重载交通标准轴载,并提出了一种标准轴载的论证思路。

Pavement Evaluation System of Reconstructed and Extended Road

The article defines the representative vehicle types and the load distribution range of this area according to the investigation of the pavement structure and the traffic composition of several representative trunk roads in Binhai New Area of Tianjin,and at the same time,makes clear the most sensitive range of pavement structure on the variation of axle load by the mechanics computation,and finally discusses the influence of axle load variation on the pavement design indexes of axle load conversion,deflection and etc.The article determines the standard axle load of the heavy load traffic in Binhai New Area of Tianjin,and puts forward a demonstration thought of the standard axle load.
