The drum is rotated for a specified number of revolutions. Afterward, the aggregate is removed from the drum and sieved on a No. 12 (1.70 mm) sieve. The aggregate retained on the sieve is weighed and the difference between this weight and the original weight is expressed as a percentage and reported as the L.A. abrasion loss value.

Aggregate Crushing Value (Ten Percent Fines) provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load.
