AS 1141.30.1-2009

Scope

This Standard sets out the method for determining a quality classification of coarse aggregate by visual comparison with pre-prepared reference specimens.
The method is used to determine the proportion of particles in a sample with different quality characteristics which can be distinguished by visual characteristics. In some sources, it may be difficult to establish a rock quality classification based on visual comparison alone. In such cases the method is inappropriate.
The method requires that the rock source, or sources from which the test sample is derived, is known. Where a sample contains a combination of aggregate from different sources, each component of the combination must be from a visually recognizable source.
The method is appropriate for material up to 75 mm nominal size and tests that fraction of the material retained on the 4.75 mm sieve.
A procedure for preparing reference specimens is detailed in AS 1141.30.2. Reference specimens prepared in accordance with AS 1141.30.2 are necessary for the completion of this test.
