    May 05, 2010· Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements. Crushing value of aggregates indicates its strength.Aggregate Crushing Value Test Determine Aggregate,Aggregate crushing value is defined as the percentage by weight of the crushed (or finer) material obtained when the test aggregates are subjected to a specified load under standardized conditions, and the strength of the aggregate used in road construction is expressed by numerical index.

  • Aggregate Crushing Value Test Significance & Test

    The crushing value of aggregates is measured in the ratio between the crushed aggregates, obtained from the IS sieve 2.36mm and the weight of the dried aggregate sample. At least three samples should be tested from the same batch and average value to get accurate results. The crushing value of aggregate = (W2/W1) x 100Aggregate Crushing Value Test Procedure And Result,Aggregate Crushing Value Test is important to test to be performed on aggregate.
