Soil Classification
Soil is classified according to characteristic properties such as:
- Cohesion: cohesive soils (silt, clay) versus non-cohesive soils (sand, gravel, boulder).
- Grain size: fine-grained soils (silt, clay) versus coarse grained soils (sand, gravel, boulder).
The first classification can be performed by the Atterberg Limits Test as follows:
- Liquid Limit Test
- Plastic Limit Test
- Shrinkage Limit Test
The second classification can be performed as follows:
- Grain Size Analysis
- Hydrometer Test
