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 545 MPa.
