Relative Density

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].

The determination of the density of different types of soil is carried out according to [ASTM D7263] and/or DIN 18125-1 and -2 [DIN18125:1997/9].

The compaction as a result of compressive loads that act onto the soil and press it together is characterised by the stiffness module E_s .
