• ### Aggregate Crushing Value Test

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.

Feb 25, 2012 From the experiment, we get average percent wear are 22.34 still not exceeding JKR’s standard, 30 . So we can conclude that the aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load.

• ### Aggregate Crushing Value Test Procedure Civil4m

Oct 04, 2020 The aggregate crushing value is an indirect measure of crushing strength of the aggregates. Low aggregate crushing value indicates strong aggregates, as the crushed fraction is low. Thus the test can be used to assess the suitability of aggregates with reference to the crushing strength for various types of pavement components.
