This report constitutes a review of the literature concerning recycling of portland cement concrete pavements by crushing the old pavement and reusing the crushed material as aggregate in a number of applications. A summary of the major projects conducted by state transportation departments is included. Crushed portland cement concrete is shown to have been successfully used in the following applications: (1) Graded-aggregate bases; (2) Cement-treated bases; (3) Asphalt base courses and pavements; (4) Portland cement concrete bases (econocrete) and pavements; (5) Source of supply for independent commercial operations selling aggregates. In any given circumstance the cost and availability of new aggregate and the cost of disposing of the old concrete play important roles in establishing whether or not recycling is a desirable alternative. Consequently, each project or the general situation for a given area must be examined separately and the decision made on the basis of local conditions.
