Sustainable Asphalt Pavements Using Bio-Binders from Bio-Fuel Waste

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, a 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 byproducts and wastes that can be used as a replacement for bituminous adhesives/binders derived from fossil fuels for asphalt pavements. The chemical structures of the residue from fossil fuel processing and bio-fuel processing proved to be somewhat different. The Bio-Oil contains more oxygen (therefore, oxygen bearing organic functional groups, such as alcohols and ketones [-OH and C=O]). The Bio-Oil is more functionalized and polar in nature. Chemical structure studies were carried out by spectroscopic methods (nuclear magnetic resonance (NMR)), infra-red, and thermal gravimetric analyses, as well as solubility in a series of solvents. Future work would involve (1) studying a wider variety of Bio-Oil derived samples, (2) employing further analytical techniques, and (3) determining how the Bio-Oils can be converted to chemical structures more similar to the petroleum derived oils.
