    Apr 13, 2020 Greater is the aggregate crushing value, softer is the aggregate sample and vice versa. This is suggestive of the fact that the resistance of aggregates to crushing is less. Therefore, the strength of such a sample is also less. Aggregates having relatively less ACV can be used in wearing surfaces of pavements
