Aggregate Crushing Value Test Determine Aggregate
Aggregate crushing value = (W2 x 100) / (W1W) W2 =Weight of fraction passing through the appropriate sieve W1W =Weight of surface dry sample The mean of two result to nearest whole number is the aggregate crushing value The aggregate crushing value of the given sample= Aggregate Crushing Values for Roads and Pavement ConstructionFor this reason assessment of strength of the aggregate is made by using a sample of bulk aggregate in a standardized manner This testing method is known as an aggregate crushing value test Aggregate crushing value provides the resistance of an aggregate sample to crushing under gradually applied compressive loadAggregate Crushing Value Test Procedure and Result
