摘　　要：我国当前正处于大跨径桥梁建设的高峰期,大跨径桥梁面临着从“以建为主”向“建管并重”的转换。ERS作为国内主流铺装方案,在国内高温重载条件下,部分桥梁出现了车辙、推移、裂缝、坑槽等病害,影响铺装使用寿命和服役性能。但ERS作为国内新型铺装方案,使用时间相对较短,对其病害梳理、使用性能评估以及相应的养护技术研究几乎为空白。现结合典型桥梁长期使用性能跟踪观测,对ERS铺装典型病害类型、成因及发展规律进行了梳理分析,建立了ERS典型病害权重系数、性能评价指标等级以及全寿命周期养护决策体系,并针对典型病害,提出了相应的处治技术,可为铺装科学养护和长期性能保持提供支撑。China is currently at the peak of the construction of long-spa bridges,which is also faced with the transition from construction-based to construction-management equilibrium.ERS is a mainstream paving scheme in China.Under the conditions of high temperature and heavy load in China,some bridges have rutting,sliding,cracks,potholes and other diseases,which affect the service life and service performance of the pavement.However,as a new domestic paving scheme,ERS has been used for a relatively short period of time,and research on its distress sorting,performance evaluation and corresponding maintenance technology is almost blank.Combining with the long-term performance tracking observation of typical bridges,the typical disease types,causes and development rules of ERS pavement are sorted out and analyzed.The typical distress weight coefficient,performance evaluation index level and whole life cycle maintenance decision-making system of ERS are established.In view of typical distress,corresponding treatment technologies are proposed,which can provide support for scientific maintenance of pavement and long-term performance maintenance.
