摘　　要：自2009年10月通车以来,运行八年的长江大桥通车量持续增长,加之长江江面风大、潮汐等气候原因,主桥面产生了裂缝、坑槽等病害,行车安全和社会问题越发凸显。综合考虑建设、养护和周报交通组织需要,科学评估对大桥主桥钢桥面进行大修施工。分别对施工准备、铣刨清理、溶剂型防水层施工、GA-10生产配合比试验和SMA高弹生产配比试验、GA-10浇注式和SMA-10高弹施工、检测结果等方面进行了具体的分析讨论。该工程取得了宝贵的施工经验,可供今后类似工程参考和借鉴。Since its opening in October 2009, the traffic capacity of Changjiang River Bridge for 8-year operation continues to increase. In addition, owing to the climate reasons that Changjiang River is windy and there is the climate reason of tide, the cracks, pits and other diseases occur in the main deck, and the traffic safety and social problems are becoming more prominent. The article comprehensively considers the needs of construction, maintenance and surrounding traffic organization, scientifically evaluates the overhaul construction of the steel deck of the main bridge, and analyzes and discusses the construction preparation,milling planer cleaning, solvent-type waterproof layer construction, GA-10 production mix ratio test, SMA high-elastic production mix ratio test, GA-10 pouring and SMA-10 high-elastic construction and the testing result in detail. The valuable construction experience achieved from this project can be referred for the similar projects in the future.
