基于性能和寿命周期成本的路面预防性养护措施选择

Selection of the Pavement Preventive Maintenance Treatments Based on Performance and Life Cycle Cost

为践行《广东省“十四五”干线公路养护管理提升行动方案》,在归纳总结近年来高速公路沥青路面预防性养护成功经验的基础上,结合某高速公路沥青路面实际技术状况检测结果,探索以养护措施性能和寿命周期费用为指标的最佳预防性养护方案的确定方法。研究结果有益于完善全寿命周期效益最优的公路养护科学决策体系,规范现有高速公路预防性养护措施选择程序,为高速公路预防性养护方案和施工图设计提供科学依据。

In order to practice the“Guangdong Province Trunk Highway Maintenance Management Promotion Action Plan within the 14th 5-Year Period”,this paper tries to summarize the successful experiences of highway asphalt pavement preventive maintenance in recent years.Combined with the actual asphalt pavement condition data collected from a highway,this paper explores the method for the best preventive maintenance treatment based on the maintenance treatment performance and life cycle cost.The results of this study are beneficial to improving the scientific decision-making system of highway maintenance with the best whole life cycle benefit,standardizing the selection procedure of the existing expressway preventive maintenance treatment,and providing a scientific basis for the preventive maintenance scheme and construction drawing design of the expressway.
