Abstract

Abstract:

As the main component of pavement crack silicone sealing (PCSS) material, the silicone material with highly cross-linked network structure makes PCSS material have excellent adhesion, water resistance, aging resistance, and high and low temperature. Therefore, PCSS material has become one of the important repair materials for pavement crack treatment. This paper reviewed the research progress of pavement crack silicone sealing materials. Firstly, according to the failure causes of PCSS materials, three failure modes of PCSS materials were summarized, namely, low temperature failure, high temperature failure and (rain) driving load failure. Various road performance requirements of PCSS materials to be met were summarized and proposed according to failure modes. At the same time, the preparation methods and research progress of PCSS materials were reviewed. Based on the modification methods of silicone structure, PCSS materials were divided into physical modification and chemical modification. The establishment of PCSS material evaluation method and its shortcomings were summarized. Finally, the development prospect of self-healing silicone sealing materials in the field of crack repair was prospected, which provided some theoretical guidance and technical reference for the application of silicone sealing materials in the field of crack repair.

Key words: pavement crack, silicone, sealing material

摘要：

高度交联网络结构的聚硅氧烷材料作为路面裂缝聚硅氧烷密封（PCSS）材料的主要组分，使PCSS材料具有优异的附着力、防水性、耐老化性、高低温性，已成为路面裂缝处理的重要修补材料之一。首先根据PCSS材料失效原因，归纳了PCSS材料的三种失效模式，即低温失效、高温失效和（雨水）行车荷载失效。基于失效模式总结提出PCSS材料需满足的各种路用性能要求；同时综述了PCSS材料的制备方法和研究现状，并根据PCSS材料中主要成分有机硅结构的改性方法，将PCSS材料分为物理改性和化学改性两大类；并针对PCSS材料评价方法的建立以及存在的不足进行了概述；最后展望了自愈合聚硅氧烷密封材料在裂缝修补领域中的发展前景，为聚硅氧烷类密封材料在路面裂缝修补领域中的应用提供一定理论指导和技术参考。
