The test aims at looking for the forces required to produce 10% of fine values (i.e. weight of fines aggregates/weight of all aggregates = 10%). This test is very similar to Aggregate Crushing Test in which a standard force 400kN is applied and fines material expressed as a percentage of the original mass is the aggregate crushing value.

This document outlines a procedure for determining the aggregate crushing value (ACV) of road construction aggregates. The ACV test applies to aggregates between 10mm and 14mm in size. The procedure involves compacting aggregate samples into a cylinder, applying a load of 400kN over 10 minutes, then sieving the crushed material to determine the percentage passing a …
Report the mean as the aggregate crushing value, unless the individual results differ by more than 0.07 times the mean value. In this case repeat the test on two further specimens, calculate the median of the four results to the nearest whole number, and report the median as the aggregate crushing value.
