The objective of this work was to determine if RCA is suitable for use in concrete on NJDOT projects and if so, what limitations there are to its use. In order to answer these questions a review of previous published reports was performed along with a review of the experiences other state DOTs have with the material. This was followed by laboratory testing of RCA produced in New Jersey. This New Jersey produced RCA was then used as aggregate in concrete field trials. The trials included cast-in-place and precast applications.
