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. aggregate possessing low aggregate crushing value should be preferred. Object: To determine the aggregate crushing value by compressive testing machine.
The aggregate crushing value (ACV) of an aggregate is the mass of material, expressed as a percentage of the test sample. which is crushed finer than a 2,36 mm sieve when a sample of aggregate passing the 13,2 mm and retained on the 9,50 mm. GET A FREE QUOTE.
The aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Attributing to its durability and resistance to abrasion, the entire range of the aggregate crushing value apparatus offered by us is widely praised.
Aggregate crushing value (wet or dry) percentage (m/m) = ACV B A = x 100 where : A = mass of test sample before test. B = mass of fraction passing the 2,36 mm sieve.
Nov 03, 2013· Aggregates with lower crushing value indicate a lower crushed fraction under load and would give a longer service life to the load and hence a more economical aggregates if used would get crushed under traffic loads, would produce smaller pieces not coated with binder and these would be easily loosend out reasulting in loss ...

APPLICATIONS OF AGGREGATE CRUSHING TEST: 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 cans be used to assess the suitability of aggregates with reference to the crushing strength for various types of pavement components.
