The aggregate crushing value test is normally carried out on aggregates between 10 mm and mm in scale In this test a recommended by the BIS code Bureau of Indian Standards
Crushing test One of the model in which pavement material can fail is by crushing under compressive stress A test is standardized by IS 2386 part IV and used to determine the crushing strength of aggregates The aggregate crushing value provides a relative measure of resistance to crushing
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 10mm and Procedure to determine Aggregate Crushing Value i The aggregates passing through
The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load With aggregate of aggregate crushing value 30 or higher the result may be anomalous and in such cases the ten percent fines value should be determined instead The material for the standard test

• Aggregate Crushing Value The aggregate crushing value gives a relative measure of resistance of an aggregate to crushing under a gradually applied compressive load To achieve a high quality of pavement aggregate possessing low aggregate crushing value should be preferred • The aggregate comprising the test sample is dried in an
The aggregate crushing value is calculated using the formula mentioned earlier Significance The crushing strength test is pivotal as it provides insights into the ability of aggregates to bear loads without failure This information is critical for selecting aggregates that ensure the structural integrity of pavements 2
1 Los Angeles Abrasion Test 2 Deval Abrasion Test 3 Dorry s Abrasion Test However the Los Angeles abrasion test is preferred since these test results have a good correlation with the performance of the pavements The Los Angeles apparatus [Below Figure] consists of a hollow cylinder m inside diameter and m long with both ends
3 This document gives the determination of aggregate crushing value ACV of aggregates This gives a relative measure of the resistance of the aggregate crushing under the gradually applied compressive load The method is applicable to aggregates passing a 14 0 mm test sieve and retained on a 10 0 mm test sieve
The test methods given in this standard are intended to assist in assessing the quality of aggregates In a given situation for a particular aggregate it may not be necessary to assess all thequalities and therefore it is necessary to determine beforehand purpose for which a concrete is being used and the qualities of the aggregate
The aggregate crushing value is calculated using the formula mentioned earlier Significance The crushing strength test is pivotal as it provides insights into the ability of aggregates to bear loads without failure This information is critical for selecting aggregates that ensure the structural integrity of pavements 2
The Crushing Value test measures the ability of an aggregate to resist crushing under a compressive load It is a measure of the strength and toughness of the aggregate In this test a standard crushing load is applied to a prepared aggregate sample and the percentage of fines generated after the specified amount of crushing is determined
