摘要

This study is to search the mechanism of crumb rubber modified asphalt and to supply some theoretical support for utilizing crumb rubber modified asphalt successfully and reasonably. In the present study, the rule of oil component absorbed by crumb rubber from catalyzed slurry oil, aromatic hydrocarbon extract oil and vacuum residue with temperature and time was investigated. It was found that during the action of crumb rubber and medium, absorbed oil component ratio first increased and then dropped as temperature and time increased in catalyzed slurry oil and vacuum residue. However, it increased in aromatic hydrocarbon extract oil under the same conditions. The ratio of absorbed oil component in vacuum residuum is lower than those in catalyzed slurry oil and aromatic hydrocarbon extract oil. And crumb rubber released some large molecule component and black carbon into medium. At the first time the study find the proof of component exchange between crumb and asphalt but not by presumption.
