Aggregate Crushing Value = 100(W2/W1) percent where: W2 = Weight of fraction passing the appropriate 2.36 mm sieve. W1 = Weight of dry sample. Normally, the percentage of fines should fall between 7.5 and 12.5. If it falls outside this range, conduct a new test at a load adjusted to bring the percentage of fines within the range of 7.5 to 12.5.
