| 摘 要： | 钢桥面铺装是一项世界性难题,特别是一些特殊桥梁,对桥面铺装提出了更高的要求.为此分析了大纵坡、小半径钢桥面铺装的施工特点和使用要求,提出了有针对性的树脂沥青组合体系(ERS)钢桥面铺装解决方案.ERS钢桥面铺装主要由环氧黏结碎石层(EBCL)防水抗滑黏结层、树脂沥青混凝土(RA05)整体化层和沥青玛蹄脂碎石(SMA)表面功能层组成,各层功能明确.室内试验结果表明,ERS钢桥面铺装具有较高的强度、良好的变形能力和施工和易性.该方案在杭州湾大桥海中平台匝道桥成功应用,解决了大纵坡、小半径钢桥面铺装的技术难题,具有较好的推广应用前景.

| Abstract: | Steel deck pavement is a world wide problem especially on special steel bridge.Based on the analysis on the construction problem and special requirements of steel deck pavment on the bridges with high lognitudinal slope and small turning radius,the paper presents a new kind of steel deck pavement,called ERS steel deck pavement.It contains three layers,such as Epoxy bonding chips layer(EBCL) and resin asphalt mixture(RA05) and stone mastic asphalt(SMA).EBCL is used as waterproof,bonding and antiskid layer,RA05 is used as an integrated layer and the SMA10 is used as a surface functional layer.Indoor test results show that ERS steel deck pavement has excellent performance and good workablity.The new pavement structure is used on the steel bridge connecting Hangzhou Bay Bridge with sightseeing flat.It solved the difficult problem successfully. |
