Methods of testing soils for engineering purposes: method 5.7.1: soil compaction and density tests: compaction control test: Hilf density ratio and Hilf moisture variation (rapid method)

This Standard sets out a rapid method for determining compaction control parameters for soils. The method involves relating converted wet density (CWD) of the laboratory-compacted soil to added moisture (Z) without the need to determine moisture content. The test is based on standard compactive effort in accordance with AS 1289.5.1.1. If modified compactive effort in accordance with AS 1289.5.2.1 is used, experimental data must initially be accumulated for that particular soil in order for the moisture variation to be reliably assessed. Because this is a rapid method, there may be minor differences between results obtained by this procedure and results obtained by the method of compaction control given in AS 1289.5.4.1. This procedure is applicable to the portion of soil that passes a 37.5 mm sieve. Corrections can be made to values determined by this method for soil with up to 20 per cent oversize material. Soil that passes a 19.0 millimetre sieve is compacted in a 105 millimetre diameter mould. Soil that contains more than 20 per cent of material retained on a 19.0 millimetre sieve is compacted in a 152 millimetre diameter mould, further class being distinguished by the presence of calcium-rich minerals. (a) The standard was approved on behalf of the Council of Standards Australia on 10 April 2006 and supersedes AS 1289.5.7.1:1993.
