摘要
首先介绍了混凝土桥面结构性防水粘结层的特点,然后对典型结构性防水粘结层(SBS改性沥青+碎石、橡胶沥青+碎石、SBS改性乳化沥青+碎石)的路用性能进行了室内外对比试验,试验结果表明:桥面处理宜采取喷砂的方式,SBS改性沥青+碎石和橡胶沥青+碎石防水粘结层均适合做桥面防水层材料,且橡胶沥青+碎石防水粘结层路用性能相对最佳。
This paper introduced the characteristics of concrete bridge deck structural waterproof-adhesive layer. Then a series of performance comparison tests of the typical structural waterproof-adhesive layer （ SBS modified asphalt, rubber asphalt, SBS modified emulsified asphalt） were carried out. The results indicated that sandblasting processing method was fit for concrete bridge deck , and rubber asphalt and SBS modified asphalt were excellent concrete bridge deck materials, at the same time, rubber asphalt was the best one.
