Sampling for Crushing Test of Aggregate. For the Aggregate crushing value test, an aggregate sample passing through a 12.5 mm IS sieve and retained on a 10mm IS sieve is selected and dried to a temperature of 105 ºC to 110 ºC then cooled to room temperature. To fill the cylindrical measure mold about 6.5 kg of a sample of aggregate is sufficient.
