Effect of different rejuvenators on the rheological properties of aged SBS modified bitumen in long term aging

Large amount of waste asphalt mixture will be produced in the process of pavement renovation and maintenance, and the waste asphalt mixture recycling can be achieved through rejuvenation. In this paper, four rejuvenators (vacuum stream oil, cashew shell oil, corn oil and waste engine oil) with different chemical composition were selected to rejuvenate aged SBS modified bitumen (ASMB). The influence of different rejuvenators on the rheological...
