| 摘 要： | 为确定桥面铺面防水粘结层胶结材料洒布量,采用橡胶沥青和两种典型的沥青混合料,通过设计直向剪切试验和斜向剪切试验研究桥面防水粘结层的力学性能,分析不同因素对于防水粘结层剪切性能的影响．试验结果表明,加载速率的提高,粘结层最大剪切应力有呈线性增大的趋势;采用不同温度的对比试验,同样发现随温度的升高,其抗剪切能力显著衰减．可以通过剪切试验的剪应力和变形能两个指标评价其剪切性能．

| Abstract: | In order to determine the spraying amount of waterproof binder for bridge deck pavement, rubber modified binder and two typical kinds asphalt mixtures were used to analyze different factors that affect the shearing properties of waterproof bond layer by skew shear test and direct shear test, the mechanical properties of waterproof bond layer was also studied in the paper. The results show that the maximum shearing stress increases linearly as the loading speed increased, the temperature also has significant effect on the shear performance of waterproof bond layer, with the increase of temperature, the shear resistance performance became worse dramatically. The shear stress and deformation obtained from shear test can be used as the indicators to evaluate the shear resistance performance. Based on the research of above, the method of determining binder spraying amount can be proposed. |
