【Abstract】 In this paper, the pavement performance of SBR modified asphalt, especially in the fields of low temperature ductility, cracking resistance and aging resistance after these comparative tests parameters were analyzed between Kin Shi SBR modified asphalt and native produced high quality asphalt . The pavement performance was observed on the road in cold area. Meanwhile, the proper social and economical benefits of Kin Shi SBR modified asphalt were demonstrated through the analysis on the performance price ratio of two kinds of the asphalt.更多还原
