选取活化胶粉与常规橡胶粉,采用不同的加工温度制备活化胶粉改性沥青与橡胶沥青,通过高温存贮48 h后上下软化点之差以及针入度之差评价两者的存贮稳定性。试验表明活化胶粉改性沥青具有较好的存贮稳定性。同时,采用混合料试验,研究活化胶粉改性沥青混合料的路用性能。试验表明活化胶粉改性沥青混合料具有较好的马歇尔稳定度、流值、动稳定度及黏附性,可满足工程应用要求。 Activated rubber powder and conventional rubber powder were selected. Activated rubber powder modified asphalt and rubber asphalt were prepared by different processing temperatures. The storage stability of the modified rubber and rubber asphalt was evaluated by the difference between the upper and lower softening points after 48 h storage and the penetration difference Sex. Experiments show that activated rubber modified asphalt has good storage stability. At the same time, the mixture test was used to study the road performance of activated rubber modified asphalt mixture. The test shows that activated asphalt modified asphalt mixture has good Marshall stability, flow value, dynamic stability and adhesion, which can meet the engineering application requirements.
