aggregate soundness and the amount of deleterious material (clay lumps and friable particles) can be assessed for both fine and coarse aggregate. For Superpave testing, coarse aggregate is usually that which would be retained on a 4.75 mm sieve and fine aggregate the fraction which would pass this sieve.
