Does Tennessee use recycled tires in asphalt?
In 1998 the Tennessee Department of Transportation placed two projects using crumb rubber modified hot-mix asphalt using materials made from scrap tires. Each 100 pounds of hot mix contained 2 pounds of recycled rubber. The test projects, both sections of Highway 70, are located in Shelby and Dickson Counties and are about 7 miles each. TDOT is continuing to evaluate the performance of these projects.
