Allowable Aggregate Crushing Value

Aggregate Crushing Value ACV and Ten Percent Fines Value TFV These tests are a measure of the crushing properties of aggregate and use the same basic equipment The ACV test requires a standard load of 400 kN to be applied over a period of 10 minutes while the TFV test measures the force required to produce a specified depth of plunger.
