Abstract: In terms of the features of high aromatics, resins and asphaltenes, but low saturates in the heavy fraction (>350℃) of tyre pyrolysis oil, the investigation to use the heavy fraction to produce road bitumen by vacuum distillation was carried out. The results show that the properties of >420℃, >430℃, >440℃ tyre pyrolysis residual oil can meet the technical specification of petroleum asphalts for road pavement, but can not meet the requirements of ageing resistance. The analytic results indicate that the composition of the residual oil changes during the aging process. The content of aromatics and resins decreases and the content of asphaltenes increases variously, which cause the stability of asphalt colloid disperse system to become worse, and the properties of the residual oil after ageing to be deteriorated. But the residual oil shows an excellent ductility because of the extremely high content of aromatics.
