摘　　要：沥青路面具有行车舒适、噪音低及维修方便等诸多优点而在高等级路面上被广泛应用。但在刚性水泥混凝土桥面上铺筑柔性沥青路面,工程投入运营后,桥面上往往会出现推移、坑槽、钢筋腐蚀、上下层间脱空及渗水等病害引起的梁体破坏。此问题一直以来困扰着我国路面的高质量发展。BMP溶剂反应型防水材料在桥面工程中的推广和应用,成功地解决了桥梁工程中出现的以上病害,提高了工程质量,延长了工程使用寿命并取得良好的经济及社会效益。The asphalt pavement has many advantages of comfortable driving,low noise and convenient maintenance,and is widely used in high-grade pavement.However,when the flexible asphalt pavement is paved on the rigid cement concrete bridge deck,after the project is put into operation,the bridge deck will often be damaged by diseases such as displacement,pit slot,rebar corrosion,void between the upper and lower layers and water seepage.The high-quality development of pavement is always troubled by these problems in China.The promotion and application of BMP solvent reactive waterproofing material in bridge deck engineering have successfully solved the above diseases in bridge engineering.The engineering quality is improved,the service life of the project is extended,and the good economic and social benefits are achieved.
