摘　　要：针对因桥面铺装层间的抗剪强度和粘结强度不足而产生桥面铺装层剥落、松散和拥包等病害,本文研究了不同材料、不同温度对层间剪切强度及拉拔强度的影响,并对比分析了不同防水涂膜的不透水性试验。通过两种防水粘结材料的室内模拟路用性能试验,提出在相同环境条件下,SBS聚合物改性乳化沥青涂料的耐高温性较好,抗剪切强度及抗拉拔强度相对较高,为合理地选择防水粘结涂膜奠定了理论基础。In connection with common diseases existing in bridge deck pavement,such as stripping,loose and hubs due to insufficient shear strength and binding strength in layers of the pavement,the article studies impact of different materials and temperatures on shear strength and pull out strength of the layers and analyses impermeability test with various waterproof membranes.According to indoor simulated road performance test with two waterproof and binding materials under identical environmental conditions the article concludes SBS modified emulsified asphalt coating is better in high temperature resistance,shear strength and tensile strength.
