Abstract
To investigate the influence of TAFPACK-SUPER modifier(TPS)dosage on the performance of SBS-modified asphalt and its mixtures,this study systematically evaluated the high-and low-temperature stability of the composite modified asphalt through fundamental tests,including the three major indicators and dynamic viscosity test.Additionally,the high-temperature stability,water stability,and low-temperature crack resistance of the composite modified asphalt mixtures were validated using specific performance tests:rutting test for high-temperature stability,immersion flying loss test and freeze-thaw splitting strength test for water stability,and low-temperature bending test for low-temperature crack resistance.Experimental results reveal that TPS significantly enhances the high-temperature anti-shear capacity and low-temperature crack resistance of SBS-modified asphalt.A specific TPS dosage notably improves the high-temperature rutting resistance,water damage resistance,and low-temperature crack resistance of the composite modified asphalt mixtures.By comprehensively evaluating the performance of both the asphalt binder and the mixture,and aligning with specification technical requirements,a TPS dosage of 9%is recommended as optimal.关键词
