Abstract:

This study evaluated the use of recycled concrete as coarse aggregate in new concrete pavements. ; Recycled concrete aggregate (RCA) produced from demolished pavements in three geographically dispersed locations in Washington state were used to perform tests on aggregate characteristics, fresh ; concrete properties, and hardened concrete properties. Variables included the source of the RCA, percent ; replacement of coarse natural aggregate with RCA (0% to 45%), and percent replacement of portland ; cement with type F fly ash (0% or 20%). RCA from all three sources met WSDOT requirements for ; aggregates, and all fresh and hardened concrete properties met WSDOT requirements. Replacement of ; RCA for natural coarse aggregate by up to 45% by volume had no significant effects on any of the ; properties. These results indicate that high-quality RCA can be used as a replacement for a portion of the ; coarse natural aggregates in new portland cement concrete pavements in Washington State.
