为提升在役水泥路面的耐久性与服役寿命,围绕国内外水泥路面延寿修复技术研究现状,梳理了水泥路面结构的力学响应和疲劳损伤演化行为,分析了水泥路面主要病害形成机理、劣化行为和特征,总结了不同劣化行为控制技术的研究进展;基于充分利用旧水泥路面板剩余承载力的思想和旧水泥路面延寿加铺结构力学行为研究,提出了严酷环境下分离式加铺连续配筋混凝土(CRC)面板的典型加铺结构,总结了水泥路面结构服役行为的智能感知技术.研究结果表明:建立准确反映水泥路面服役行为的力学模型可为其合理设计和寿命精准预测提供科学的理论依据;在水泥路面破坏形成初期及时对其技术状况进行评价并修复,可在一定程度上延长其使用寿命;接缝传荷能力和板底脱空是影响水泥路面耐久性的显著因素,在旧水泥路面修复过程中应重点关注;旧水泥路面加铺沥青混凝土和水泥混凝土是其延寿的有效措施,从全寿命周期来看,重载交通在役水泥路面加铺CRC面板是其延寿的有效技术手段;未来应建立考虑在役水泥路面劣化行为、剩余强度等的寿命预估理论,开发高性能、易兼容和绿色环保的水泥路面延寿修复材料,借助服役性能多源异构大数据的感知与处理技术,完善在役水泥路面加铺结构设计的理论技术与行业规范,全面提升在役水泥路面的服役水平和使用寿命.
In order to improve the durability and service life of cement pavement in service,the mechanical response and fatigue damage evolution behavior of cement pavement structure were reviewed based on the research status of life extension repair technologies of cement pavement in China and abroad.The formation mechanism of main diseases,deterioration behavior,and characteristics of cement pavement were analyzed,and the research progresses of different deterioration behavior control technologies were summarized.Based on the idea of making full use of the residual bearing capacity of old cement pavement slabs and the research of the mechanical behavior of old cement pavement with overlay structure for life extension,a typical overlay structure of separated continuous reinforced concrete(CRC)slabs under harsh environment was proposed.The perceptive technology of service behavior of cement pavement structure was summarized.Research results show that the establishment of a mechanical model accurately reflecting the service behavior of cement pavement can provide a scientific theoretical basis for its reasonable design and accurate life prediction.Evaluating and repairing the technical condition of cement pavement in time at the initial stage of damage can extend its service life to a certain extent.Joint load transfer capacity and void beneath the slab are significant factors affecting the durability of cement pavement,which should be paid more attention in the repair process of old cement pavement.Overlaying asphalt concrete and cement concrete on old cement pavement is an effective measure to extend its life.In terms of whole life-cycle,overlaying CRC slabs is an effective technical means to extend the life of cement pavement in service with heavy traffic.In the future,a life prediction theory should be established by considering the deterioration behavior and residual strength of cement pavement in service,and high-performance,compatible,and environmentally friendly materials for life extension and repair of cement pavement should be developed.With the help of the perception and processing technologies of multi-source heterogeneous big data of service performance,the theoretical technology and industry norms of overlay structure design of cement pavement in service should be improved,and the service level and service life of cement pavement in service are comprehensively improved.3 tabs,8 figs,115 refs.
