The influence of synergistic effect of polystyrene and SBS on asphaltum property was researched. The results show that the addition of SBS evidently improved the compatibility between polystyrene and asphaltum. By the synergistic effect of polystyrene and SBS, the dispersion of polystyrene in asphaltum was increased;the intenerate point and penetration of asphaltum were both improved ;the ductibility and adhesion of asphaltum were not decreased.
