Scope

This Standard sets out the counting method for determining the average least dimension of aggregate particles by the use of vernier callipers or dial gauge or a slotted gauge. The method is applicable to aggregate of nominal size 10 mm and greater for sprayed bituminous surfacing.
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.
