BOONE, IOWA — The Farm Progress Show is back in central Iowa, and one of the innovations featured is a 43-thousand square foot asphalt base made from soybean oil and recycled crushed asphalt.
Iowa Soybean Association President Robb Ewoldt says this project demonstrates yet another way soybeans can be used.
Iowa State University engineering professor Eric Cochran says this project also recycles old road layers and keeps them out of landfills.
The project on display at the Boone site uses more than 23-hundred pounds of soybean oil from 215 bushels of crushed soybeans. Soybean checkoff dollars funded the soy-based asphalt.
