This paper presents chemical and rheological characterization of bio-binder produced from swine manure for use in pavements. A hydrothermal process was used to convert swine manure to a bio-oil. The bio-oil was fractionated to extract water, solid residue and some of the organic compounds. The sticky residue after fractionation was used as a replacement for asphalt binder. This paper presents production as well as chemical and rheological characterization of the bio-binder as compared with petroleum-asphalt binder. Bio-binder from swine manure found to be a promising candidate for partial replacement for petroleum-asphalt binder. Considering the increasing demand for asphalt binder for infrastructure rehabilitation and the limitations imposed on growth of swine farms by manure management practices and environmental regulations, this sustainable development will result in major improvements in environmental and economical impacts in both highway industry and the agricultural sector. Hence, this project offers a unique approach that simultaneously addresses the increased depletion of petroleum resources, the growing swine manure pollution and released greenhouse gases, and the development of sustainable alternative for petroleum asphalt. The use of bio-binder will improve petroleum-asphalt binder’s low temperature properties while reducing asphalt pavement construction costs; the cost of bio-binder production is estimated to be $0.54/gallon while that of asphalt binder is $2/gallon.
