Laboratory Evaluation of Recycled Concrete As Aggregate in New Concrete Pavements

The Washington State Department of Transportation (WSDOT) has initiated a research project to investigate the use of recycled concrete as aggregates (RCA) in Portland (hydraulic) cement concrete pavements (PCCP). The planned source for the RCA in the project will be from demolished pavements in western Washington, which generally contain very high-quality aggregates. Aggregate quality varies across the state, and concrete made with RCA sourced elsewhere will likely have different properties. This Pacific Northwest Transportation Consortium proposal is to expand the scope of the WSDOT project to include additional sources of RCA as well as evaluations of the RCA properties for the purpose of establishing performance criteria necessary for successful application in PCCP. The goal of the combined projects is to evaluate the use of RCA for widespread application in concrete pavements in Washington State and beyond.
