路面管理系统的车辆轴载调查分析

Investigation and Analysis of Vehicle Axle Load for Pavement Management Systems

结合上海市公路路面－桥梁管理系统研究，对车辆轴载进行了调查方案设计、数据调查和数据分析。通过交通量观测资料推算路面标准轴载换算次数，得出了不同交通特征道路、不同路面结构类型的车辆轴载换算系数，同时提出了路面管理系统的车辆荷载分级标准。

In this paper, on the basis of developing Shanghai Pavement and Bridge Management Systems, the procedures for vehicle axle load survey were designed. With these procedures, the survey data were collected and analysed. As a result, the method to estimate daily ESAL based on exsiting traffic survey data was demonstrated. The ESAL factors of different traffic characteristics for different pavement types were calculated. The vehicle axle load classification standards in PMS were also presented.
