Abstract: Pyrolytic carbon black (CB p ) from scrap tire pyrolysis is a potential modifier for the bitumen industry. Binders containing different contents of CB p were prepared and experimentally investigated to examine the effects of CB p on the electrical and thermal conductivity, conventional physical properties, rheological properties, high-temperature antirutting performance, aging resistance, and storage stability. Laboratory test results indicated that the incorporation of CB p effectively improves the electrothermal properties, rheological properties, high-temperature rutting resistance, and aging resistance. It also increases the viscosity and decreases the storage stability of bitumen. The study confirms that CB p -modified bitumen with proper selection of content can be a multifunctional paving material.
