Bio-Material Maintenance Treatments

The proposed research provides a proof-of-concept opportunity for further development of soy-derived bio-production into asphalt materials. The objectives are to: (1) enhance pavement longevity by using bio-based materials to soften oxidized asphalt at the surface of the pavement and sealing up cracks in the surface to prevent water infiltration; (2) enhance development of soybean-derived bio-materials for pavement maintenance applications; (3) broaden the domestic market use for agriculture products in the United States; (4) enhance sustainability of pavement materials through the use of bio-materials and reduce pavement life cycle cost through preservation treatments. The benefits of this research are improved flexibility and preservation of roadways while developing new domestic markets for soybean products. Increased longevity of the roadway delays major rehabilitation and provides improved pavement condition in the interim. Preservation of pavements helps keep roads in better condition longer which leads to reduced pavement life cycle cost.
