摘要
依托湖北沪蓉西高速公路百米溪大桥沥青混凝土铺装工程,室内试验分析了热熔橡胶粉改性沥青防水材料与SBR类和SBS类两种涂膜类防水涂料抗拉强度、抗剪强度,试验结果表明,胶粉改性沥青桥面防水层高温抗剪、抗拉性能良好,且抗施工损伤特性强。实体工程应用结果表明,热熔胶粉改性沥青桥面防水层施工工艺简单,质量易于控制,具有较好的经济效益和社会效益。
During the project of asphalt deck pavement of baimixi bridge in hurongxi expressway of hubei province,laboratory testing including tensile test,shearing test were employed to characterize the properties of hot melt rubber modified asphalt waterproofing material,SBS and SBR coated waterproof material.The results indicate that rubber modified asphalt waterproofing has good high temperature tensile,shearing resistance and construction damage resistance compared with SBS and SBR coated waterproof material.Moreover,in engineering entity application,rubber modified asphalt waterproofing layer is easy for construction,quality control and has good economic benefit and social benefit.
