May 25, 2016 . were obtained and tested for Aggregate Crushing Value (ACV), Aggregate Impact Value (AIV),. Specific Gravity, Water absorption Capacity, Bulk Density, Moisture Content and Particle Size. Distribution. On the average the results of the observation for the selected four locations were 22.56 g, 28.17 g,.

Then the aggregate crushing value is defined as the ratio of weight of fines passing the specified IS sieve(W2 gm) to the total weight of the sample (W1 gm). Two tests are done and the average value to the nearest whole number is reported as aggregate abrasion value. Aggregate crushing value= ( W2 / W1)x100.
