This document gives the determination of aggregate crushing value (ACV) of aggregates. This gives a relative measure of the resistance of the aggregate crushing under the gradually applied compressive load. The method is applicable to aggregates passing a 14,0 mm test sieve and retained on a 10,0 mm test sieve.

5.1 Impact Value, as determined using the standard 4.5 kg (10 lbm) hammer, has direct application to design and construction of pavements and a general application to earthworks compaction control and evaluation of strength characteristics of a wide range of materials, such as soils, soil aggregates, stabilized soil and recreational …
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.
4 Transportation Engineering Lab report OBSERVATION AND CALCULATION: The ratio of weight of fines formed to the weight of total sample in each test shall be expressed as a percentage, the result being recorded to the first decimal place. Aggregate crushing value = (W2 x 100) / (W1-W) W2 =Weight of fraction passing through the appropriate sieve …
