大跨径钢桥面铺装是桥梁建设和养护的关键技术之一,针对京港澳高速公路武汉军山长江公路大桥钢桥面铺装的结构特性、病害特点、外部环境、施工和使用要求等,提出了“橡胶环氧砂浆+双层SMA”钢桥面铺装设计方案。经实施后历年跟踪观测,结果表明铺装体系总体应用效果良好,基本解决了桥面铺装的推移、车辙、裂缝等重要病害,为今后大跨径钢桥面铺装技术设计及养护施工提供借鉴。
Long-span steel bridge deck pavement is one of the key technologies for bridge construction and maintenance. In view of the structural characteristics, disease characteristics, external environment, construction and use requirements of steel bridge deck pavement of Wuhan Jun Mountain Yangtze River Highway Bridge of Beijing-Hong Kong-Macao Expressway , Proposed a “rubber epoxy mortar + double-layered SMA ” steel deck pavement design. After the implementation of tracking observations over the years, the results show that the overall application of the pavement system is good, basically solved the deck decking, rutting, cracks and other important diseases for the future of large span steel deck surfacing technology design and maintenance of construction to provide Learn from
