摘　　要：依托三元立交跨京顺路桥桥面铺装专项维修工程项目,针对原桥环氧沥青混合料铺装防水层和粘结层失效,铺装层开裂、推移、拥包、剥离等病害原因进行分析,研究提出适用于北京市钢桥面铺装的浇筑式沥青混合料。铺装试验结果表明,浇筑式沥青混合料铺装能够解决原钢桥面铺装存在的问题,同时可适应北京市城市桥梁养护的实际需求,对后续北京市钢桥面铺装设计、施工等具有一定的借鉴意义。Relying on the special maintenance project of bridge deck pavement across Jingshun Road Bridge Ternary Interchange,the failure of the waterproof layer and adhesive layer of the original bridge epoxy asphalt mixture pavement,the cracking,shifting,congestion and stripping of the pavement layer are analyzed in depth,and the poured asphalt mixture pavement suitable for the steel bridge deck pavement in Beijing is studied.The test results of the real bridge pavement show that the poured asphalt mixture pavement can completely solve the various problems existing in the original steel bridge deck pavement,and at the same time,it is more suitable for the actual needs of urban bridge maintenance in Beijing,and has certain reference significance for the subsequent design and construction of steel bridge deck pavement in Beijing.
