Researchers at Iowa State University are testing a new type of environmentally friendly paving product. The product, called bioasphalt, was created by Iowa State researchers. it's made from biomass, using parts of corn or soybeans left out during food production. Bioasphalt is being tested for the first time on a section of the Waveland Trail in Ames. The hope is that bioasphalt could some day replace petroleum as the link that binds asphalt together.
Researchers estimate that bioasphalt could someday save producers almost 20 percent on operating costs.
