An aggregate specimen is compacted into a steel cylinder fitted with a nofriction plunger. The specimen is then loaded via the plunger. The load crushes the aggregate to an extent depending on the crushing resistance of the material. It is measured by a sieving test on the crushed specimen and it is a measure of the aggregate crushing value (ACV).
The aggregate crushing value test indicates the strength of aggregate which is the most essential property of coarse aggregate. The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. For achieving a high quality of pavement, aggregate of higher crushing strength low ...
