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.

Like the jaw crusher, the cone crusher provides a relatively low cost crushing solution, but there are application drawbacks that may make another crushing solution more appealing. First, cone crushers cannot accept all material sizes. Any material fed to the crusher must be pre-sized for that particular crusher (usually 200mm or less).

Corrected stress values from penetration depths of 0.100 and 0.200in (2.54 and 5.08mm) are divided by standard stresses of 1,000psi (6.9mPa) and 1,500psi (10.3mPa), then multiplied by 100. In most cases, CBR values decrease as penetration increases. The CBR value is the stress at the 0.100in (2.54mm) penetration depth.
