It is showed in wind-vehicle-bridge system vibration analysis that cross wind action can remarkably increase the response of bridge and vehicle. Generally, the response of bridge and vehicle are increased with wind speed and train speed, one case that vehicle is on leeward side of deck is more unsafe than another case that vehicle is on windward side of deck. Nonlinear factors can more influence bridge than vehicle.

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.
