ScraptiresderivedfromautomobileshavebecomealargeenvironmentalproblemintheUnitedStates. Inthisstudy,researchiscarriedouttoinvestigatethe
potentialuseoftire-derivedpyrolyzedcarbonblackfromscraptiresasanasphaltcementmodifier.
TheasphaltcementsusedinthisresearchwereAC10andAC20. Penetrationandsofteningpointtestswereperformedtoobtaintheconsistencyoftheasphalt
