Symbol | Description | Density index (ID) for noncohesive soils/liquidity index (IL) for cohesive soils |
|---|---|---|
I | Uncontrolled anthropogenic soils (brick rubble, clay, sand), appearing in a plastic state | IL = 0.50 |
IIa | Fine grain, moist sand appearing in semi-compacted state | ID = 0.45 |
IIb | Medium grain sands, coarse, moist sand, appearing in a semi-compacted state | ID = 0.40 |
IIIa | Hydrated sand-gravel, appearing in a semi-compacted state | ID = 0.50 |
B1 | Phyllosilicate clays, sandy clays, dust with phyllosilicate sand layers, moist, appearing in a plastic state | IL = 0.43 |
B2 | Phyllosilicate clays, sandy loams, dust with phyllosilicate sand layers, moist, appearing in a hard-plastic state | IL = 0.18 |
D | clays, sandy clays, silts, wet, damp, appearing in a compacted or semi-compacted state | IL < 0.00 |
