Workshop September 28 on impacts of using recycled materials along unpaved roads

On Thursday, September 28, the Institute for Transportation (InTrans) at Iowa State University will hold a workshop for county engineers to detail the results of a new project using recycled materials on unpaved roads.

The project found that engineers can use more recycled materials along unpaved roadways. The study found that existing roads can be maintained using 50% to 60% less virgin aggregate, or fresh rock, to uphold the surface quality of the road. New road maintenance methods can save time, cut costs, improve road performance and reduce overall environmental impact compared to traditional road designs.

The workshop is supported by the Iowa Department of Transportation and the United States Environmental Protection Agency.

Attendees will hear from ISU instructors Jeramy Ashlock, the Richard L. Handy Associate Professor of Civil Engineering in the geotechnical area, Kristen Cetin, an associate professor in the Department of Civil, Construction and Environmental Engineering (CCEE) in the construction engineering group, and Bora Cetin, an assistant professor in the geotechnical and geoenvironmental engineering area in CCEE.

The workshop will begin at 9 a.m. at InTrans, 2711 South Loop Drive, Suite 4700 in Room 4040. Attendees need to register for the event by Monday, September 25. There is no cost to attend the workshop. For more information contact Bora Cetin at 515-294-2140 or
