Abstract
This study tries to combine crumb rubber(CR)and styrene-butadiene-styrene(SBS)to modify the asphalt binder to improve the high-temperature performance.Firstly,the high and low temperature performance of CR or SBS modified asphalt binders were investigated;then,based on the conventional performance tests,the effect of CR content on CR and SBS composite modified asphalt binders was evaluated,among which the SBS content in the CR and SBS composite modified asphalt is fixed at 2%;at last,with employment of dynamic shear rheometer(DSR),multiple stress creep and recovery(MSCR)scanning was applied on the each samples,where non-recoverable creep compliance(Jnr)and percentage recovery(R)were obtained to characterize the anti-rutting performance of the CR and SBS composite modified asphalt binders.The results reveal that the CR and SBS composite modified asphalt binder(2%SBS and 10%CR)exhibited better than SBS modified asphalt binder(4%SBS),in terms of anti-rutting performance.关键词
