The low temperature properties of the binders were greatly improved, the dynamic mechanical properties of SBR-modified asphalts before and after oxidation or sulfurization were characterized at -30~100℃ by using dynamic shear rheometry. The results show that the addition of SBR1500 increased the binder elasticity at low temperature.
