The purpose of this research was to characterize the fundamental properties and to evaluate the performance of asphalt mixtures modified by pyrolyzed carbon black (CBp) as an additive and air-cooled furnace slag as a coarse aggregate. Laboratory tests were conducted at INDOT and Koch Materials. The optimum binder content and the relationship of density and voids were determined from Marshall mix design. The rang of optimum binder content was 6.3% to 7.8%. The Marshall stability as a strength value and flow increased within the accepted ranges due to the inclusion of CBp. The gyratory tests were conducted by the US …

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 …

This study presents the viability of using PCB as an additive in hot mix asphalt concrete. Different ratios of PCB (5%, 10%, 15%, and 20% by weight of asphalt) were blended with two grades of asphalt (AC-10 and AC-20). The complete behaviors of the PCB modified asphalt concrete were investigated by comprehensive laboratory testing and evaluation. The Marshall method was used to determine the optimum binder content and the mechanical properties and void relationships were investigated by this method. The Gyratory Testing Machine was used to define the stress-strain relationships of the PCB mixtures. The rutting potential of PCB mixtures …
