高粘沥青在桥面防水粘结层中的应用研究

Research on the Application of High-Viscosity Asphalt to Adhesive Layer for Bridge Deck Waterproofing

高粘沥青和普通改性沥青相比而言,具有较高的粘度、粘韧性和韧性。在不同粘层厚度条件下,对3种粘层材料进行了抗剪强度试验,确定了3种粘层厚度与性能的关系;另外在不同温度条件下,分别对3种粘层材料进行了抗拉强度、抗剪强度及渗水性能试验,试验表明,温度对粘层材料的的抗剪强度和抗拉强度有较大的影响,在高温条件下,高粘沥青的抗剪和抗拉性能明显好于其他2种粘层材料。

Comparing with modified asphalt,the viscosity,toughness and tenacity,and toughness of high-viscosity asphalt are higher.We do shear strength tests on the three adhesive layer materials under different thicknesses and we present the relationship between the three thicknesses and the performance in this article.In addition,we do shear strength tests,tensile strength tests and seepage tests on the three kinds of adhesive layer materials under different temperatures.According to the tests,we can see that the temperature has great effect on shear strength and tensile strength of adhesive layer material, especially under the high temperature, the shear performance and the tensile performance of adhesive layer materials are better than the other two.
