Mar 10, 2019 The crushing value test of aggregate provides the resistance of an aggregate sample to crushing under gradually applied compressive load.Generally, the test is conducted on aggregate passing 12.5 mm and retained on a 10 mm sieve.The aggregate sample is filled in a cylindrical mold and a load of 40 tons is applied through a plunger in a compression testing machine.
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. It is recommended that the crushing value of aggregate should be less than 30 .
The aggregate crushing value is an essential index in the construction of road bases and is defined as the mass percentage of fine particles after a confined compression test of recycled CDW.
