Aggregate Aggregate Crushing Value Interpretation

Aggregate crushing value test.

The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied compression load. Aggregates possessing high resistance to crushing or low aggregate crushing value are preferred for use in high quality pavements. The apparatus for the standard test consists of a steel cylinder 152 mm diameter with a ...
