PORTLAND CEMENT CONCRETE RECYCLING: TECHNOLOGY REVIEW

A review of current technology pertaining to the recycling of existing portland cement concrete pavements was conducted. The purpose was to assess the applicability of recycling to U.S. Air Force pavement rehabilitation work. Costs of alternatives were reduced to simple models for use in evaluating sensitivity to cost factors. A study of projects on which this technology was used identified aggregate cost and haul distance as key factors. Numerous other factors also affect the results. Technological deficiencies were studied, and most were found to be the result of lack of experience with the technology. No substantially new technology is involved in recycling portland cement concrete. (Author)
