Scope

This Standard sets out the method for calculating the median size and average least dimension (ALD) of an aggregate using the nomograph method. The method is applicable to aggregates for bituminous surfacing having a nominal size 7 mm and greater.
NOTE: The first use of the term ‘average least dimension’ is attributed to F.M. Hanson, MM, in the paper ‘Bituminous surface Treatment of Rural Highways’ published by the New Zealand Society of Civil Engineers (Incorporated in 1935) Present practice is outlined in the AUSTROADS publication (AP2/90), Design of sprayed seals, 1990.
