摘要：
Heavy fraction pyrolytic oil of waste tire reclaim rubber vacuum pyrolysed at 600 degrees C (HR6) was produced. Then, it was considered as a rheological modifier for road bitumen. Addition of HR6 to bitumen was increased penetration and decreased softening point. Rutting temperature and temperature susceptibility of bitumen was improved using this rheological modifier. The bitumen containing 5% of HR6 showed optimum level in comparison to different concentration was used. Ductility of modified bitumen has significantly increased. Rheological behavior of modified samples was studied through static and dynamic tests, which showed good improvement in complex viscosity, modulus and damping factor; respectively. Very good low temperature flexibility observed by bending beam rheometer (BBR) test proposing flexible behavior in winter. Moreover, the aging by rolling thin film oven (RTFO) and storage stability was studied and reported.
