Supplies of natural mineral aggregates are diminishing even as usage increases. Disposal problems exist because of steadily increasing accumulation of solid wastes. In light of these two situations an investigation was made to evaluate the use of crushed waste concrete similar to pavement concrete as concrete aggregates. A discarded concrete driveway that contained siliceous aggregates and a laboratory concrete beam that contained limestone as coarse and natural siliceous sand as fine aggregate were selected to represent pavement concretes. Portions of each kind of concrete were processed into aggregate sizes. Three concrete mixtures were made to evaluate the driveway concrete as aggregate, and two other mixtures were made to evaluate the crushed concrete beam as aggregate. (Author)
