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. 2)Hardness

natural aggregate deposits, called pit-run gravel, consist of gravel and sand that can be readily used in concrete after minimal processing. Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed. Crushed stone is produced by crushing quarry rock, boul-ders, cobbles, or large-size gravel. Crushed air-cooled
