摘要
以相关研究成果为基础,对公路沥青路面预防性养护的各项关键技术进行系统研究和阐述。以理论分析为主,结合室内试验和试验路观测,明确了路面预防性养护的定义和技术理念;分宏观和微观两个层面提出了公路沥青路面预防性养护的路况指标和标准;建立了预防性养护对策及措施选择的方法和流程,并给出了相应示例;以路面预养护措施的费用效益分析为核心提出了最佳预防性养护时间的确定方法和相关参数。该文提出的理论、方法、技术和参数初步建立了我国路面预养护的技术框架,可供相关的研究和应用参考。
Taking the relative studying result as the basis, the article systematically studies and setsforth various key preventive curing technologies of highway asphalt pavement. Giving priority to the theoretical analysis and combined with the indoor test and the trial road observation, the article makes clear the definition and technical idea of preventive pavement curing, puts forward the index and standard of preventive asphalt pavement curing for the highway from two macroscopic and microcosmic layers, sets up the selecting method and flow of preventive curing countermeasures and measures, and gives the relative demonstration, and puts forward the determining method and relative parameter of the optimized preventive curing time taking the cost benefit analysis of pavement preventive curing measure as the core. The article puts forward the theory, method, technique and parameter preliminarily to set up the technical framework of pavement preventive curing in China able to provide the studying and application reference.
