Also, the samples are classified according to the strength and rock types, and the effect of this classification is investigated based on the relationship between rock strengths and AD properties.

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. Granular sub-base is subjected to repeated loadings from truck types. The stress level at the contact points of aggregate particles is quite high.
