Using Pyrolized Carbon Black (Pcb) From Waste Tires In Asphalt Pavement (Part 2, Asphalt Binder), Yongdong Zeng, C. W. Lovell

JTRP Technical Reports

Scrap tires derived from automobiles have become a large environmental problem in the United States. In this study, research is carried out to investigate the potential use of tire-derived pyrolyzed carbon black from scrap tires as an asphalt cement modifier. The asphalt cements used in this research were AC10 and AC20. Penetration and softening point tests were performed to obtain the consistency of the asphalt cements. The pyrolyzed carbon black, as provided by Wolf Industries, was combined with the asphalt cement in the following percentages; 5%, 10%, 15% and 20%. Penetration, softening point and ductility tests were performed to determine …
