The actual crushing value of an aggregate is a relative measure that shows the resistance to crushing under a slowly applied compressive load. ... (ACV) can be determined by using a simple formula: This test is repeated once or twice and the average crushing value of the aggregate is determined.

Explanation: After the impact test is conducted, the results are obtained in percentage. The aggregate is said to be exceptionally tough when the value is 10%, very tough when the value is in between 10 - 20%, good for pavement surface when the value is in between 20 – 30% and weak if the value is >35%.
