Recycled Aggregates
Only up to 10 to 20 percent fine RCA is beneficial. The aggregate should be tested at several substitution rates to determine the optimal rate. Often recycled aggregate is combined with aggregate when used in new concrete. An example of a mix design using recycled aggregates in a pavement appliion is shown following table.
