In this study, bio-binder was used as asphalt binder modifier (2% and 8%) as well as asphalt binder extender (25% and 50%). Therefore, it is important to investigate the physical, chemical and rheological properties of the developed bio-binder. Tests results showed that vacuum distillation process can be used to effectively dehydrate the fast pyrolysis bio-oil. Both CGMB and RSMB have higher penetration than Pen 60-70. The chemical composition of both CGMB and RSMB are similar to the vast majority of the Pen60-70 except the bio-oil modified binders are rich in oxygen content. Increasing CG and RS bio-oil content result in decreasing complex shear modulus (G*).
