Production of Asphalt Rubber Concrete by the Dry Process Author(s): Anderson, Chris, Iowa DOT Origin: Iowa Date: April, 1994 Categories: Performance Key Words: asphalt rubber concrete, crumb rubber modifier, dry process, tire recycling Summary: A test section was placed in Shelby County using rubber modified hot mix with the dry process. A double drum mixer was used that introduced the rubber with the bag house fines return. Conclusions are that temperatures lower than used for the wet process could be used. No special provisions for productions and placement were required. Performance evaluations are planned.
