摘　　要：通过室内模拟路用性能试验,研究了环境温度对3种桥面防水粘结材料的组合剪切强度、组合拉拔强度及组合不透水性的影响,并对3种桥面防水粘结材料的综合性能进行了比较分析,得出在相同环境条件下,与SBS改性乳化沥青及SBR改性乳化沥青相比,氯丁胶类涂料的耐高温性较好,抗剪切强度及抗拉拔强度相对较高,是一种优良的防水粘结材料。The influence of ambient temperature on the combined shearing strength,combined gluing strength and combined water-impermeability of the three kinds of waterproof and cohesive materials for bridge deck were studied through indoor tests. According to the comparative study on the comprehensive performances of three waterproof and cohesive materials,it was proved that compared with SBS modified emulsified asphah,SBR modified emulsified asphalt,under the same ambient conditions,polychloroprene coating presents a better heat resistance and the shearing strength and gluing strength are relatively higher, so it is a good waterproof and cohesive material.
