AGGREGATE CRUSHING VALUE This test helps to determine the aggregate crushing value of coarse aggregates as per IS: 2386 (Part IV) – 1963. The apparatus used is Cylindrical measure and plunger, Compression testing machine, IS Sieves of sizes – 12.5mm, 10mm and 2.36mm. Procedure to determine Aggregate Crushing ValueCrushing Value of Aggregate - Welcome to Virtual Labs,The aggregate crushing strength for various types of surface course of pavements should be high enough to withstand the high wheel load, including the steel tires of loaded bullock-carts. However, low strength aggregates having lesser crushing strength are used in base and sub-base courses of pavements. IRC have specified aggregates crushing values of the coarse aggregates used foraggregate crushing value limit - SmartTech,Aggregate crushing Value percentw2 w1100 26 43 Aggregate crushing value W2 W1 100 771 2917 100 26 43 RECOMMENDED VALUES The suitability of aggregate is adjudged depending on its proposed use inthe pavement layers Specified limits of percent aggregate crushing value for Aggregate Crushing Value Civil Engineering. AGGREGATE CRUSHING VALUE,METHOD B1 THE DETERMINATION OF THE AGGREGATE CRUSHING,,confined aggregate sample under a specified, gradually applied compressive load and determining the percentage of the material crushed finer than a specified size.
