Theory: The “aggregate crushing value” give a relative measure of the resistance of an aggregate to crushing under gradually applied compressive load. It’s the percentage by weight of the crushed(finer) material obtained when the test aggregates are subjected to a specified load under standardized conditions, and is a numerical index of the strength of the aggregate used in road construction.

Calculation of Aggregate Crushing Value. 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 100. Lab Report
