Abstract
This study investigates the use of Bio-Binder, derived from swine manure, as an additive to improve rheological properties of bitumen extracted from recycled asphalt shingles. Test results show that adding Bio-Binder to Recycled Asphalt Shingles (RAS) leads to reduced viscosity, modulus shear complex G*, relaxation time RT and segregation. Results illustrated that the derived Bio-Binder additive can remove the negative impact of oxidation and rejuvenate bitumen extracted from recycled asphalt shingles.
