摘　　要：随着交通事业的迅速发展和公路等级的提高，桥梁在高速公路中所占比重日益增加。沥青混凝土桥面铺装层在经受车辆重复荷载的振动、冲击、拉伸、剪切、动水压力等力学作用的影响，以及由于温度、气候变化引起膨胀、收缩后.Combined with the preventive maintenance of deck of Gonghua No.1 Bridge on Jingzhu Expressway,by comparing some preventive maitenance methods,SPRR technology was chosen in the end.The construction process of SPRR technology and the requirements for equipments and materials were expounded in details.One year after the maintenance,the effect was evaluated,and the results show that SPRR technology can fix the cracks in bridge deck surface,and prevent water-seepage;at the same time,it can add binder for the old surface and stabilize loose aggregate to treat the diseases on bridge deck.The new bridge deck after treatment would be blacker and safer.
