6. If no specific dry density is requested, fill the sample ring until it is completely full and
the surface is flush (planar) with the soil sample ring.
If required, cut overlapping material with a knife.
7. For storage, place the two covers on the sample ring.
8. Place the soil sample ring in the refrigerator in the lab.
2.5 SATURATE SOIL SAMPLE
The next preparation step is to saturate the soil samples. The following sections explain out
to properly saturate the different sample types.
Gather the tools listed below prior to saturating the soil sample:
• Filter paper—large
• Filter paper—small
• LABROS Saturation plates (2)
• Weight
• Tray
• Tap water at room temperature
2.5.1 UNDISTURBED SOIL SAMPLE
Follow the steps below to saturate an undisturbed soil sample.
1. Take the soil sample out of the refrigerator.
2. Remove the cover on the noncutting side of the sample ring.
If soil material is protruding above the top of the sample ring, cut off the protruding
material until the surface is flush (planar) with the top of the sample ring.
Cut a little bit at a time along the edge of the sample ring and be careful not to smudge
the surface and close the pores (
).
