The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. To achieve a high quality of pavement, aggregates possessing low aggregate crushing value should be preferred. Why to test Aggregate Crushing Value? The principal mechanical properties required in road stones are: Satisfactory resistance to crushing under the roller,Aggregate crushing value test | Step by Step Procedure,,Aggregate Crushing Value (ACV) can be determined by using a simple formula: This test is repeated once or twice and the average crushing value of the aggregate is determined. The average crushing value in the different tests is the actual crushing value of aggregate. Important points to remember .

Tamping rod; Weigh balance; IS Sieves -(12.5mm,10mm &2.36mm) Procedure of the test. Aggregate sample shall consists of particles passing on 12.5mmDETERMINATION 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 The apparatus of the aggregate crushing value test as per IS: 2386 (Part IV) – 1963 consists of: 1) ACrushing Value of Aggregate - vlab.co.in,The test conducted to know the compressive strength of aggregate is known as aggregates crushing value test. The crushing value of aggregates is rather insensitive to variation in strength of weaker aggregates. For this reason, a simple test known as 10 percent fine value is introduced. When the aggregates crushing value become 30% or higher, the results are likely to be inaccurate.Aggregate Crushing Value (ACV) and Ten Percent Fines,Aggregate Crushing Value (ACV) and Ten Percent Fines Value (TFV) These tests are a measure of the crushing properties of aggregate and use the same basic equipment. The ACV test requires a standard load of 400 kN to be applied over a period of 10 minutes while the TFV test measures the force required to produce a specified depth of plunger,
Aggregate Crushing Value (ACV) - Civil Engineering
Aggregate Crushing Value (ACV) The aggregate Impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact, which in some aggregates differs from its resistance to a slowly applied compressive load. With aggregate of aggregate impact value higher than 30 the result may be anomalous.Aggregate crushing test - Strength of aggregate,,28/03/2021· Aggregate crushing test values indicates the strength of aggregate and hence it is very significant. Similarly we can say crushing value is the relative measure of resistance of an aggregate under gradually applied compressive loads. Higher crushing strength means lower crushing value and vice versa. If the aggregate crushing value is less than 10, means an exceptionally strong aggregate,BS 812-110:1990 - Testing aggregates. Methods for,,The method is not suitable for testing aggregates with an aggregate crushing value higher than 30, and in such cases the method for ten per cent fines value described in BS 812-111 is applicable.
