The pyrolytic oil reside (POR) is produced during vacuum pyrolysis of waste tire powder (WTP) at 600 °C. Then, the pyrolytic oil residue is considered as a rheology modifier for bitumen at low temperatures. Characterization of POR showed lower viscosity and flash point with same elemental analysis to neat bitumen. Interestingly, the POR provides high-content resin (~ 20%) and similar C/H to resin part of neat bitumen which caused the increase in ductility. By blending POR with bitumen, penetration increased and softening point decreased. Short-term aging properties (compatibility, retained penetration) displayed improvement in aging resistance. Stiffness curves of bending beam rheometer (BBR) at − 12 °C proposed a winter-flexible binder by adding POR. Also, rotational viscometry (RV) indicated shear-thinning behavior of modified bitumen. The validity of this assumption was confirmed during dynamic shear rheometer (DSR) study. Damping factor considered an enhancement in soft viscous performance of modified bitumen at low temperatures in comparison to neat bitumen.
