摘　　要：为了评价不同类型桥面防水黏结层材料的性能,在实验室对水性环氧沥青、橡胶沥青和SBS改性沥青三种防水黏结层材料进行不同洒布量、温度、浸水和冻融条件下的抗剪切和拉拔性能试验.研究结果表明:三种防水黏结层材料的耐腐蚀性和不透水性均较优,水性环氧沥青的黏结强度、低温柔韧性、高温耐热性、温度敏感性、水稳定性、抗水损坏性均优于橡胶沥青和SBS改性沥青;推荐橡胶沥青、SBS改性沥青和水性环氧沥青分别采用洒布量为1.6、1.4、1.0 kg/m 2进行工程应用.In order to comprehensively evaluate the properties of different types of waterproof bonding materials for bridge deck,shear and drawing resistance tests under different sprinkling amount,temperature,water immersion and freeze-thaw conditions of three kinds of waterproof bonding materials,i.e.,waterborne epoxy binder rubber asphalt and SBS modified asphalt were carried out through laboratory tests.The results show that the three waterproof bonding materials have better corrosion resistance and water impermeability.The bonding strength,low temperature flexibility,high temperature heat resistance,temperature sensitivity,water stability of waterborne epoxy asphalt and resistance to water damage are better than those of rubber asphalt and SBS modified asphalt.It is recommended that for distributing quantity of rubber asphalt,SBS modified asphalt and waterborne epoxy asphalt,1.6 kg/m 2,1.4 kg/m 2 and 1.0 kg/m 2 can be used respectively for engineering application.
