Standard Test to Determine the Relative Density of the Soil
The standard test used to determine the compaction of soil samples in the laboratory is the proctor compaction test per [ASTM D698] and [DIN18127:1997]. Compaction in accordance with this standard is “to increase the dry density (decrease the pore percentage) of the soil by means of mechanical impacts” [DIN18127:1997].
