养护后评估是总结养护工程实施效果的重要工作。在综合考虑交通量、原路面结构等不同因素的前提下，选取了12个研究试验路段、4种典型养护措施进行长期的跟踪观测。根据观测数据分析了修复性养护后裂缝、IPCI在不同因素影响下的发展规律；并提出了养护效果评价指标—主要病害修复效果指数、养护措施寿命延长指数和养护措施寿命指数；经济效益评价指标—经济效益指数，并将评价方法应用于湖南省高速公路沥青路面典型养护对策后评估，分析了各因素对路面性能的影响及养护经济效益。为合理选择养护措施提供参考。
Post-maintenance evaluation is an important work to summarize the implementation effect of maintenance projects. On the premise of considering different factors such as traffic volume and original pavement structure, 12 research test sections and 4 typical maintenance measures were selected for long-term tracking observation. According to the observation data, the development law of cracks and IPCI after repair maintenance under the influence of different factors is analyzed. The evaluation index of maintenance effect-main disease repair effect index, maintenance measure life extension index and maintenance measure life index are put forward. The economic benefit evaluation index-economic benefit index is applied to the post-evaluation of typical maintenance countermeasures of expressway asphalt pavement in Hunan Province, and the influence of various factors on pavement performance and maintenance economic benefits are analyzed. It provides reference for reasonable selection of maintenance measures.
