The aggregates crushing value test should be performed as per IS code 2386 Part IV. First, fill the sample aggregate with one-third of the cylindrical measure in three layers. Each layer should be tamped 25times freely. After filling the sample aggregate, weigh and record it as W1. Now fill the aggregate in the mould along with the plunger on top.

Crushing Value Test of Aggregates – Importance, Procedure, and Standard limits. The aggregate crushing value test on coarse aggregates gives a relative measure of an aggregate under a gradually applied compressive load. It is a numerical index of the strength of the aggregates. This test is helpful in the construction of roads and pavements.

2. It is the intent of this test method to only determine the percent of crushed particles created by crushing or other mechanical means and not the additional crushed/fractured aggregates created by laboratory processes. With this in mind, it is important that the tester handle aggregates for this test carefully. J. HEALTH AND SAFETY

The Los Angeles (L.A.) abrasion test (Figure 1) is a common test method used to indicate aggregate toughness and abrasion characteristics. Aggregate abrasion characteristics are important because the constituent aggregate in HMA must resist crushing, degradation and disintegration in order to produce a high quality HMA.

The strength of coarse aggregates is determined by the aggregates crushing test. The aggregate crushing value test provides resistance of an aggregate to crushing under a gradually applied compressive load. To construct a high quality of pavement, aggregate possessing low aggregate crushing value should be preferred.

Procedure of Aggregate Impact value test. The test sample: normally aggregates sized 10.0 mm to 12.5 mm. the aggregates should be dried by heating at 100-110 0C for a period of 4 hours and cooled. Sieve the material through 12.5mm and 10.0 mm IS sieves. The aggregates passing through 12.5 mm sieve comprises the test material.
