环氧沥青钢桥面铺装以其优越的力学性能和材料特性而受到广泛关注,然其长期性能需进一步验证。对南京长江二桥桥面铺装进行系统的分析,开展包括铺装病害分析、平整性、抗磨耗性、抗滑性能等方面的研究,并采用红外线成像技术,探究铺装表面功能。结果表明:环氧沥青铺装使用性能尚好,仅在使用过程中出现些许病害;铺装层抗滑性能较建成之初有所改观;铺装表面功能发生了较明显的变化,并分析了其成因。建议管养部门有针对性地制定表面性能恢复的预防性养护对策。
Epoxy asphalt bridge deck pavement with its superior mechanical properties and material properties have received widespread attention, but its long-term performance needs further verification. The Nanjing Yangtze River Bridge deck surface analysis of the system to carry out including pavement disease analysis, formation, abrasion resistance, skid resistance and other aspects of the study, and the use of infrared imaging technology to explore the pavement surface function. The results show that the performance of epoxy asphalt pavement is good, and there is only a little disease during the application. The anti-slip performance of pavement layer is improved compared with that at the beginning, and the function of pavement surface is obviously changed. Cause. It is recommended that the management department formulate preventive preventive measures for the restoration of surface properties in a targeted manner.
