AGGREGATE CRUSHING VALUE 1.Objective The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggregate of aggregate crushing value 30 or higher, the result may be anomalous, and in such cases the ten percent fines value should be determined instead.
Aggregate suitable for use as pipe bedding would display a low compaction fraction, indicating it reaches a state of near full compaction under loose placement. Test Method Crushing Value The Aggregate Crushing Value offers a related measure of the resistance of an average to crushing under a compressive load that is gradually applied.

The standard aggregate impact test shall be made on aggregate passing a 14.0 mm BS test sieve and retained on a10.0 mm BS test sieve. If required, or if the standard size is not available, smaller sizes may be tested but owing to the non-homogeneity of aggregates the results are not likely to be the same as those obtained from the standard size.
Crushing in an impact crusher takes place when the stone is struck by the spinning impact bars, and by that stone being flung against an apron. When impact crushing is used, the striking of the aggregate by the spinning rotors blow bars knocks off or breaks the elongated fractures. This process is repeated by an impactor in the secondary stage.
