The aggregate crushing value is defined as the ratio of the weight of fines passing through specified IS (here 2.36mm sieve) to the total weight of sample expressed in percentage. W1= Weigh of the total aggregates (Wa-We) W2= Weigh of aggregates passing through 2.36mm IS sieve.
Calculate Aggregate Crushing Value. The ratio of the weight of fines formed to the total sample weight in each test shall be expressed as a percentage, the result being recorded to the first decimal place: Aggregate Crushing Value = W B W A × 100. Where, W A is weight of surface-dry sample
Jan 25, 2018· 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.
