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.

HIGHWAY CONSTRUCTION MATERIAL & PRACTICE

Bituminous Materials Bituminous material, or bitumen in the form of asphalt, is one of the major highway construction materials used. Asphalt is normally a residue product from the distillation of crude oil and, as refined, is a heavy, viscous material that is semisolid at normal atmospheric temperatures. By controlled processing or blending desired viscosity and hardness characteristics can ...
