Figure 4: Division of groups A and B by the soil compaction curves of this research In the second cut-off point, it is observed that group B is subdivided into two other groups (B-1 and B- 2), while group A remains the same (showing that the soils of this group have more homogeneous characteristics than the soils of group B). This part of the clustering may have been made based on the granulometric composition, especially by the silt and fine sand fractions of the soils. The subdivision of group B into B-1 and B-2 was due to the high % of fine soil sand 03IT-NA' (55.85%), which differentiated it from the other soils of the group, as can be seen in the graph of Figure 5.
