基于试验室研究分析了沥青胶浆和SBS聚合物改性沥青结合料PMAB的工程性质,如物理性质、用改良的马歇尔方法测试的马歇尔值、不同温度下的静态间接抗拉强度、抗拉强度比、沥青混凝土AC和SBS改性沥青混凝土PMAC的回弹模量。结果表明:PMAB的温度敏感性比基质沥青低;PMAC混合料的马歇尔稳定度和流值高于AC混合料;不同温度下PMAC混合料的静态间接拉伸强度值高于AC混合料;PMAC混合料的水稳定性不如AC混合料。
Based on laboratory studies, the engineering properties of asphalt mortar and SBS polymer-modified asphalt binder PMAB were analyzed, such as physical properties, Marshall values with a modified Marshall method, static indirect tensile strength at different temperatures, tensile strength Rebound Modulus of Asphalt Concrete PMAC with AC and SBS Modified Asphalt Concrete. The results show that: the temperature sensitivity of PMAB is lower than that of matrix asphalt; the Marshall stability and flow value of PMAC are higher than that of AC; the static indirect tensile strength of PMAC is higher than that of AC; The water stability of the material is inferior to AC mixture.
