Gravel roads account for more than 60 percent of the roads managed by Iowa counties. However, until now, there haven’t been readily available tools to help agencies evaluate granular material costs versus field performance.

To help agencies evaluate and optimize their operational strategies for their granular material purchases and use, researchers recently created the Granular Roads Asset Management System (GRAMS) spreadsheet tool. More
