AGGREGATE CRUSHING VALUE
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 Crushing Value (ACV)
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.

Crushing Value Test of Aggregates
The standard aggregate crushing test is done on aggregates passing 12.5 mm sieve and retained on 10 mm sieve and make those surface dry by heating at 11 to 110°C for four hours and cooled to room temperature. Surface dry aggregates are filled into the standard cylinder in three-layer. Each layer should be tamped 25 times, finally levelled off using a tamping rod as the straight edge.

Standard of Crushing Value of Coarse Aggregates for Permeable Asphalt
Crushing resistance of coarse aggregate is the key to the stability and durability of the skeleton structure of permeable asphalt (PA) mixture. To determine the technical requirements of crushing value of coarse aggregate used in PA mixture, step-loading compression tests were conducted on the mixtures of PA-13 and a control asphalt mixture AC-13, respectively.
