Increase the Allowable Content of Recycled Crushed Concrete Fine Aggregate in Class P Concrete

The production of recycled crushed concrete coarse aggregate generates a substantial quantity of recycled crushed concrete fine aggregate, which is limited for use in Class P concrete. The current maximum allowable limit of 20% recycled crushed concrete fine aggregate is an arbitrary limit with little basis. This project will determine the limits of recycled crushed concrete fine aggregate that can be used in Class P concrete and still produce workable and durable concrete pavement. Researchers will conduct field trials with actual Class P mix designs with various recycled crushed concrete fine aggregates and conduct lab testing to validate mix designs developed, to include surface wear, carbonation, or durability testing, etc.
