with a Liquid Limit grater than or equal to 50 percent are high compressible (H).
FIGURE 16. SOIL CLASSIFICATION CHART
For a low compressible fine-grained soil the possible classifications are shown in Figure 16 above:
The high compressible soils have an LL equal to or above 50 percent. Their possible classifications are
shown in Figure 16 above:
The only classification we have left is the symbol for peat which is PT. Peat is a fibrous organic
material such as peat moss. It is completely unsuitable for construction and is identified visually.
