Title: The Mechanism of Asphalt Modification by Crumb Rubber
Abstract: To investigate the mechanism of asphalt modification by crumb rubber, the interactions between FCC slurry and rubber particles were evaluated at different temperatures and time. The rules of the change in mass of SARA composition in FCC slurry were obtained before and after its interaction with rubber particles, which showed that crumb rubber not only absorbed saturates and aromatics but also resins. Asphaltenes promoted the desulfurization or degradation of crumb rubber during the interaction between asphalt and crumb rubber.
