基于沥青路面使用性能衰变规律的养护规划技术研究

Research on Maintenance Planning Technology Based on Use Performance Decay Law of Asphalt Pavement

研究沥青路面使用性能在行车荷载、环境和时间综合作用下的衰变规律是编制路面养护规划的基础工作,是路面养护科学决策的具体体现。文章结合高速公路养护实际需求,以广西A高速公路为例,优化验证了现行路面损坏状况指数PCI算法与路用性能标准衰变模型,提出了一种基于路用性能衰变规律的中长期养护规划编制方法。

Studying the decay law of asphalt pavement performance under the combined effect of driv- ing load,environment and time is the basic work of preparing the pavement maintenance planning, and it is the specific embodiment of scientific maintenance decision-making. Combining the actual needs of expressway maintenance, and with A expressway in Guangxi as the example, it optimized and verified the current pavement damage status index PCI algorithm and road performance standard decay model, and proposed a medium and long-term maintenance planning preparation method based on road performance decay law.
