摘要/Abstract

摘要： 以不同轴限下车辆轴载分布的统计和预测数据为基础,根据我国干线公路(国道+省道)的里程、路面类型、使用年度以及主要的养护维修方法,计算分析了不同轴限下国道每年的大修养护费用.结果表明,轴限提高至13 t时,道路的养护维修费用急骤增长,增长幅度较大;并且轴限愈高,轴限约束水平对道路养护维修费用的影响愈敏感.

Abstract: Based on the statistic data and prediction data of the vehicles in China, the axle load distribution models of four axle load limits were developed.According to pavement types and axle load distributions of different axle load limits, the pavement life was calculated.In the case of the main highway's (national and provincial highway) mileage, grades, past years, pavement types and maintenance approaches in China, the annual maintenance cost of different axle load limits was estimated.The results showed that axle load limit affected the pavement maintenance cost greatly, especially, when axle load limit reached 13 ton, the annual pavement maintenance cost would increase greatly.And, the axle load limit becomes bigger, and the enforcement level will become more sensitive to pavement maintenance cost.

Key words: axle load limit, axle load distribution, pavement life, maintenance cost
