Federal Highway AdministrationUnited States. Federal Highway AdministrationFederal Highway AdministrationThe purpose of this review was to capture the most advanced uses of recycled concrete aggregate (RCA) for transportation uses in the United States. This knowledge would then be transferred to all State Transportation Agencies (STA) in the United States through the issuance of this report. The report summarizes the information collected during the review of practices in five states, Texas, Virginia, Michigan, Minnesota and California. These states were selected based on their level of use and supply generated of RCA as an aggregate as well as to obtain a cross-section of the country. This report identifies the applications where the use of RCA can have engineering, economic, and environmental advantages; the barriers related to these RCA applications; and the best practices that allowed State Transportation Agencies, recycled concrete producers and contractors to overcome these barriers. The report is intended to provide the State Transportation Agencies with recommendations, guidelines and specifications for furthering the use of RCA more widely throughout the country.
