Balancing the Aromatic and Ketone Content of Bio-oils as Rejuvenators to Enhance Their Efficacy in Restoring Properties of Aged Bitumen

The potential of the bio-oil from the co-pyrolysis of poplar wood and waste tire rubber to revitalize severely aged bitumen was examined by shifting the balance of aromatics and ketones in the bio-oil. Laboratory experiments were performed to compare the revitalization efficiency of bio-oils from the pyrolysis of poplar wood and co-pyrolysis of wood and waste tire rubber. Furthermore, the chemical compositions of the bio-oils from both processes...
