• ## 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 less than 30% can be used for cement concrete road. The aggregate whose crushing value is less than 40% can be used for wearing surface. This test must be done before it comes to road and pavement construction.

• ## Aggregate Crushing Value Test – Procedure and Result

Aggregate Crushing Value Test is important to test to be performed on aggregate. The strength of aggregate parent rock is determined by preparing a cylindrical shape specimens of size 25 mm diameter and 25 mm height. This cylinder is subjected to compressive stress. Depending on the type of parent rock gives different compressive strength varying from a minimum of about 45 MPa to a maximum of
