This Standard sets out the method for determining the angularity number of an aggregate. The angularity number is a measure of relative angularity based on the percentage voids in an aggregate after compaction in the prescribed manner.

This Standard sets out the method for determining the angularity number of an aggregate.The angularity number is a measure of relative angularity based on the percentage voids in an aggregate after compaction in the prescribed manner. The least angular (most rounded) aggregates have about 33% voids. The angularity number is defined as the amount by which the percentage of voids exceeds 33. The angularity number ranges from 0 to about 12.Since considerably more compactive effort is used in the angularity test than in the determination of unit mass (see AS 1141.4), the results of the two tests are different. Also, weaker aggregates may be crushed during compaction, and the angularity number test does not apply to any aggregate that breaks down under test.NOTE: For information on uncertainty of measurement, see Appendix.
