Also known as sieve analysis, this test is done to determine if the aggregates are fit for purpose.

The arithmetic mean of all the measured least dimensions of the aggregate particles measured. 

A measurement of the flatness of an aggregate, affecting the performance of road surfacing aggregates and the workability of concrete.

Reveals relative proportions of dust or clay-like materials, used to assess the quality of fine aggregate used in concrete and asphalt.

Determines the particle strength of aggregate for concrete, surfacing (chips) and asphalt, as well as for crushed stone base.

Simulates the resistance of aggregate to the polishing action of vehicle tyres under conditions similar to those occurring on a road surface.

Determine the relative compaction of a crushed stone base and mix design procedures of concrete and asphalt where volumetric and water absorption properties are required.

This test is used to determine the apparent density of crushed stone base. The results are used to determine compliance of the density with applicable specifications.
