Aggregate Crushing Value (ACV) The aggregate Impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact, which in some aggregates differs from its resistance to a slowly applied compressive load.
Nov 03, 2013· Te test mould- a 15.2 cm diameter open ended steel cylinder with squqre base plate ; plunger having a piston of diameter 15cm, from a hole provided across the stem of the plunger so that a rod could be inserted for lifting the plunger in the cylinder.
The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. To achieve a high quality of pavement, aggregate possessing low aggregate crushing value should be preferred.
The strength of coarse aggregate is assessed by aggregate crushing test, the aggregate value provide the relative measure of resistance to crushing under gradually applied compressive load. Lesser the aggregate crushing value greater will be the "resistance to crushing under gradually applied compressive load".
