Abstract: Taking Suizhong 36-1 70^# asphalt as matrix asphalt, minus three line furfural extract oil as compatilizer, the effects of four modifiers on the conventional, high temperature shear rheological and thermal storage properties of suizhong asphalt were investigated. The morphological characteristics of SBS phase in asphalt under different modifiers were analyzed. The results show that the modified asphalt prepared by the modifier A has excellent performance in the high and low temperature and it has good compatibility with Suizhong asphalt. With LG501S, YH791, A and B as the modifier, the rut factor G*/sinδdelta of modified asphalt increases gradually, and the high temperature performance is enhanced. By screening the modifiers and stabilizers, the modifier A and stabilizer 2^# are selected as raw materials for the production of I-D modified bitumen from Suizhong 36-1 asphalt.
