Aggregate crushing value test Step by Step Procedure. It is recommended that the crushing value of aggregate should be less than 30%. If it is more than 30 % then 10% finer aggregate is suggested to use. The aggregate whose crushing value is .
Therefore, aggregates used in road construction must be hard enough to resist Abrasion. The resistance offered by the aggregate to Abrasion is determined in the laboratory by the Los Angeles testing machine.. The Los Angeles abrasion test's working principle is to produce abrasive action using standard steel balls, which, when mixed with aggregates and spun in a drum for a .

· If the aggregate crushing value is less than 10, it signifies an exceptionally strong aggregate. Whereas, if the crushing value is 35 or above, it would normally be considered as weak aggregate. After performing the test, the crushed material is separated and calculated in terms of percentage of the original weight taken in the mould.
Test Procedure. Take the sample sand and fill the measuring cylinder up to 200 ml. To make the necessary correction use the steel rule but don't compact the sand. Transfer that sample to a container. Refill the measuring cylinder with 100ml water. Now refill the sand into measuring cylinder and stir it well with the help of steel rod.
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. 5 NOTES The test described above is the standard test but if the available aggregate does not contain
· The apparatus of the aggregate impact value test consists of: A testing machine weighing 45 to 60 kg and having a metal base with a plane lower surface of not less than 30 cm in diameter. Level and plane concrete floor of minimum 45 cm thickness are used to support it. The base of the machine should also have provisions for fixing its base.

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. 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.
· Aggregates with lower crushing value indie 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 of the surface.

· Aggregate crushing test. The strength of the aggregate can be assessed by conducting this test. The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Size of recycled aggregates taken for conducting test was between and 10mm.
· The Los Angeles test is a measure of degradation of mineral aggregates of standard gradings resulting from a combination of actions including abrasion or attrition, impact, and grinding in a rotating steel drum containing a specified number of steel spheres. The Los Angeles () abrasion test is a common test method used to indie aggregate toughness and abrasion
