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. Aggregate crushing value=( W2 / W1 ) × 100Aggregate Crushing Value Calculator, Test on course and,,Aggregate used in road construction, should be strong enough to resist crushing under traffic wheel loads. If the aggregates are weak the stability of the pavement structure is likely to be adversely affected. The strength of coarse aggregates is assessed by aggregate crushing test.Aggregate Crushing Value - Civil Engineering,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 Value.DETERMINATION OF AGGREGATE CRUSHING VALUE,The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Crushing value is a measure of the strength of the aggregate. The aggregates should therefore have minimum crushing value. 3. APPARATUS(PDF) Road Construction Materials Basic Knowledge,Calculations Aggregate Crushing Value (ACV)Some aggregate particles resist crushing while some crush during rolling (due to the effect of weathering process or micro-fractures developed by blasting or crushing operations). Crushing of aggregates during construction process affects the grading, density and strength of a mix or layer made with such aggregate.To measure resistance of aggregate to,An Investigation Into Quality Of Aggregate In Road,,These two aggregate samples were tested for sieve analysis test, relative density test, water absorption test, ten percent fine test, aggregate crushing value test (ACV), Aggregate impact value test (AIV), and Abrasion value test. Findings revealed that the best aggregate for road construction is the aggregate from Isi-Agu.
