Biobased materials and byproducts of bio refineries are explored as alternative materials to replace the fossil fuel-based binders. Biomass or biowaste are processed and chemically treated to a compatible form to blend with asphalt binder homogeneously. In this study, gasifier byproduct of pine needle biomass was investigated as a potential replacement of asphalt binder. Replacement up to 20 % was studied and the binders were chemically characterized using FTIR and TGA. Correlations were developed between the chemical indices and the physical properties. For morphological analysis, imaging studies were performed using AFM. It was found that the gasifier bio-condensate has some potential for use as a replacement for asphalt binders. The bio-condensate also showed a rejuvenation effect, as observed from chemical and morphological studies.
