目前，不同种类的无缝式伸缩缝材料在使用过程中其高温性能、低温性能、变形性能和病害特征存在较大差异。针对这些差异，对无缝式伸缩缝材料的研究现状及成果进行了梳理，总结了当前研究存在的不足，并对未来的研究方向进行了展望。首先，根据填缝胶结料的种类，将无缝式伸缩缝胶结料划分为改性沥青材料和聚氨酯材料两类，并对其性能和评价指标进行了梳理。然后，针对两类材料的混合料组成设计方法、混合料性能的测试方法和评价指标进行对比分析。最后，根据材料性能差异，推荐不同服役环境下适宜采用的无缝式伸缩缝材料。目前，无缝式伸缩缝的研究在混合料组成设计、性能评价方法、破坏指标、经济效益等方面仍然存在不足，建议从材料的性能优化、多指标评价体系的建立、材料与结构的一体化等方面开展下一步研究。

At present, there are great differences in the high and low temperature performance, deformation performance and disease characteristics of different types of seamless expansion joint materials in the use process. In view of these differences, this paper reviews the research status and achievements of seamless expansion joints materials, summarizes the current research deficiencies, and looks forward to the future research directions. Firstly, according to the types of plug joints binders, the plug seamless expansion joints binders are divided into two categories: modified asphalt materials and polyurethane materials, and their properties and evaluation indexes are sorted out. Then, the composition design methods, test methods and evaluation indexes of mixture performance of two kinds of materials are compared and analyzed. Finally, according to the difference of material properties, the suitable seamless expansion joints materials for different service environments are recommended. Currently, the research about seamless expansion joints is still insufficient in the aspects of mixture composition design, performance evaluation methods, damage indicators, economic benefits, etc. It is suggested to carry out the next research from the aspects of material performance optimization, establishment of multi index evaluation system, and integration of materials and structures.
