The effects of two liquefying processes and three biological oil sources on the performance of modified biological asphalt were compared and analyzed.DSR and BBR were used to study the effects of SBS modifier content and biological asphalt content on the high and low temperature performance of modified biological asphalt.The main effect was obtained by using range analysis,and the performance of modified biological asphalt was optimized by controlling the main effect.The road performance of the mixture of modified biological asphalt,SBS modified asphalt and ordinary petroleum asphalt studied in this paper is compared and analyzed.
