This standard specifies a method for determining the 10% fines aggregate crushing value (FACT value) of a coarse aggregate sample. The FACT value is measured by crushing the aggregate sample and determining the force required to produce 10% fines, which are particles that pass through a 2,360 micrometer sieve. The test can be performed in either dry or wet conditions.

Aggregate crushing value Test and Procedure. With aggregate of aggregate crushing value 30 or higher, the result may be anomalous, and in such cases the ten percent fines value should be determined instead. Crushing value is strength of the aggregates against crushing load. Aggregates undergo crushing in road construction and road operation work.

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. A data sheet is given as Form 7.7.1.
