Methods of testing soils for engineering purposes, Method 5.3.5: Soil compaction and density tests - Determination of the field dry density of a soil - Water replacement method
工程用土壤试验方法 方法5.3.5:土壤压实和密度试验-土壤现场干密度的测定-水置换法
This Standard sets out the method for determining the field dry density of a natural or compacted coarse-grained soil by the water replacement method, using a circular density ring on the surface and a plastic sheet to retain the water (see Notes 1 and 2). This test is particularly appropriate for soils containing appreciable proportions of cobbles and boulders as defined in AS 1289.0, e.g. rock fill.
