First, the actuality of Jiangyin bridge's deck surfacing are reviewed. Improper materials and pavement structures, severe conditions, overload and heavy traffic are deemed to be the main factors which result to deterioration of the deck surfacing. Then, programme of local repair asphalt mixture design has been proposed. It is considered that epoxy asphalt mixture and guss asphalt mixture are propitious to the local repair. The epoxy asphalt is also chosen as the adhesive layer material. Next, two pavement structures for steel deck plate surfacing have been tested. The most suitable asphalt surfacing structures have been proposed for the local repair. Finally, the elaborate local repair schemes of Jiangyin bridge's deck surfacing are proposed.

论文首先调查评估了江阴桥桥面铺装的现状，分析了江阴桥桥面铺装破坏的原因，认为材料及结构选用不当、使用条件苛刻、超载与大交通等是主要原因；其次对修复铺装混合料进行了配合比设计，认为优化后的环氧沥青混合料与浇注式沥青混合料适合于江阴桥的铺装修复，而粘结材料则采用环氧沥青粘结剂；然后参考国内外已有的桥面铺装结构组合，对两种复合结构进行了比较研究，提出了适于江阴桥桥面铺装局部修复的铺装结构组合；最后在各项研究的基础上，提出了江阴桥桥面铺装局部修复的具体方案。
