Sustainable Asphalt Pavements Using Bio-Binders from Bio-Fuel Waste (KSU)

Asphaltic binders that are used for asphalt pavements have been traditionally obtained either from fossil fuels or from natural sources. However, due to growing interest in sustainability, search has been initiated for a non-petroleum binder that could be used for asphalt pavements. The objective of this study is to develop a modified asphalt binder from bio-refinery by-products and wastes that can be used as a replacement of bituminous adhesives/binders derived from fossil fuels for asphalt pavements. The internal chemical structures of the residue from fossil fuel processing and biofuel processing are similar. Thus, necessary chemical changes would be minimal to produce the appropriate viscosity and aging index for use in asphalt mixtures. The bio binder properties will be modified using bio-polymers resulting in a better binder that will have enhanced wetability and coating (adhesion) and resistance to aging (loss of volatiles) properties.
