Dept. of TransportationCleary, Douglas B.Rowan UniversityUnited States. Federal Highway AdministrationUS Transportation CollectionAggregates can be produced by crushing hydraulic cement concrete and are known as recycled concrete aggregates (RCA). This report provides results from a New Jersey Department of Transportation study to identify barriers to the use of RCA in new Portland cement concrete and to provide a recommendation as to whether this material should be permitted on Department of Transportation projects. The report includes a review of previous studies of RCA, a summary of the experiences of other transportation agencies with the material, and summary of the additional laboratory and field trials performed as a part of this study. A recommendation is made to allow RCA to be used in non-structural roadway applications. Recommended specifications are provided
