Performance evaluation of bio-oil modified asphalt mixes

Bio-oils are thought to be potentials for petroleum binders used in asphalt pavement because of the renewability and environmental friendliness. The present study explores the application potential of wood bio-oil as a replacement to conventionally used asphalt binder in flexible pavements. The chemical structures and rheological properties of bio-oil and bio-bitumen were investigated and compared with petroleum bitumen. The rotational viscometer, dynamic shear rheometer, rolling thin film oven were conducted to evaluate the rheological properties of biooil modified asphalt binders. The pavement performance of asphalt mixtures, including Marshall stability, moisture susceptibility and deformation resistance performance were evaluated.
