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