摘　　要：The effects of styrene-butadiene-styrene(SBS)pre-swelling/extraction process and the incorporation of C9 petroleum resin on the anti-aging performance of modified asphalt were systematically evaluated by characterizing the physical indexes,chemical compositions and rheological parameters.The experimental results show that the SBS pre-swelling/extraction process and the incorporation of C9 petroleum resin improve the dispersion performance of SBS in asphalt as well as the strength of SBS polymer network structures,and the synergistic effects decrease the volatilization degree of asphalt lightweight components and the degradation rate of SBS during the aging process.The anti-aging performance of SBS modified asphalt(SBSMA)was significantly enhanced by SBS pre-swelling/extraction process compounded with the incorporation of C9 petroleum resin,and the anti-aging effect was gradually enhanced with the increase of C9 petroleum resin content.
