This Standard sets out the method for determining the particle density, apparent particle density and water absorption of aggregates substantially retained on a 4.75 mm sieve, by weighing in water in a pycnometer.
NOTE: An aggregate containing more than 10 percent of material passing a 4.75 mm test sieve is regarded as a mixed aggregate.
A mixed aggregate is separated into two fractions consisting of material retained on and material passing a
4.75 mm sieve. The density of the fine fractions is determined separately by the method AS 1141.5. The density of the mixed aggregate is calculated as a weighted average as illustrated in Clause 7(e).
