Preparation and properties of SEBS modified asphalt
WANG Ming1,YU Hongwei 1,MA Haihua2,WEI Zhen1
(1.Department of Chemistry and Material,Naval University of Engineering,Wuhan 430033,China;2.Pingdingshan Environmental Monitoring Centre Station , Pingdingshan 467000 , China)
Abstract:Modified asphalt was successfully prepared based on 70# bitumen with polymer SEBS prepared by the selective hydrogenation of thermoplastic elastomer SBS as asphalt modifier,the effects of polymer SEBS content and the shear temperature on the modified asphalt of low temperature ductility,softening point and penetration were investigated.And the optimum shear temperature and additive content of SEBS also were determined.Finally,through the change in the microstructure observed by SEM,the mechanism of modified asphalt was explained.Results of the trial indicated that modified asphalt has the best comprehensive perbance and the lowest cost of economic when shear temperature was 170鈩�and the content of polymer SEBS was 5%.
Key words:SBS;asphalt;shear temperature;SEM
