Aggregate crushing value Test Lab Report. Adnan Abir. Name of the experiment: Aggregate Crushing value test. Objective: 1. Determine the aggregate crushing value of coarse aggregate. 2. Assess suitability of coarse aggregates for use in different types of road. Theory: The “aggregate crushing value” give a relative measure of the resistance,Aggregate crushing value test  Step by Step Procedure,,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 1.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. 2.The aggregate whose,Aggregate Crushing Value Test  Significance & Test,,Calculation of Aggregate Crushing Value. The crushing value of aggregates is measured in the ratio between the crushed aggregates, obtained from the IS sieve 2.36mm and the weight of the dried aggregate sample. At least three samples should be tested from the same batch and average value to get accurate results.
