Aggregate Crushing Value (ACV) Test - Procedure, Calculations
The aggregate crushing value test determines the resistance of coarse road construction aggregates to crushing under load. This important test measures the percentage of crushed particles produced when a standard sample is subjected to gradually applied force. A lower aggregate crushing value indicates better strength for use in road bases and subbases.
