摘　　要：在小桥桥台与路面连接处设置TST弹塑体伸缩缝,能充分吸收车辆通行对小桥桥面的振动冲击,有效减少桥头裂缝,使车辆行驶舒适平稳。通过伸缩缝施工工艺过程控制,保证了施工质量。Setting TST thermoplastic elastomer expansion joints at the connection of bridge abutments and road, can fully absorb the bridge deck＇s vibration shock which come from vehicular traffic, and is effective in reducing the bridge cracks, so that make it comfortable and smooth when vehicles cross. Ensure construction quality through control the Process of construction technology on expansion joints.
