桥面防水黏结层性能室内试验分析

对4种防水黏结材料进行黏结力试验，结果表明环氧沥青的黏结效果最优。不同试验温度及喷砂构造深度下的室内剪切试验结果表明：抗剪强度随试验温度的升高而减低，且在最佳构造深度时，抗剪强度达到最大。不同试验温度、浸水及冻融条件下的拉拔试验结果表明：防水黏结材料的拉拔强度随着温度的升高而明显降低，且温度越高，衰减越快；在浸水和冻融条件下，拉拔强度出现不同幅度的下降。

Indoor Test Analysis on Performance of Waterproof Binding Course of Bridge Deck

The cohesive force test is carried out on four kinds of waterproof. The results show that the epoxy asphalt is of the optimal binder effect. The results of indoor shearing tests with different temperatures and different sandblasting structure depth show that the shear strength decreases as the test temperature increases, and when the optimal sandblasting structure depth is achieved, the shear strength reaches maximum. The results of drawing tests under the condition of different test temperatures, soaking and freeze thawing show that with the increase of temperature, the drawing strength of waterproof cohesive materials significantly reduces, the higher the temperature is, the faster the drawing strength decays, and under the condition of soaking and freeze-thaw, the drawing strength drops with different amplitude.
