Proctor Soil Compaction

Simulate compacting a soil specimen in a standard mold. Plot moisture-density relations to find the Optimum Moisture Content (OMC).

Target Moisture Content ($w$)8.0%
Dry SideWet Side
Compaction Equation:
γd=γbulk1+w/100\gamma_{d} = \frac{\gamma_{bulk}}{1 + w / 100}
Zero Air Voids (ZAV) Curve:
γzav=Gsγw1+wGs100\gamma_{zav} = \frac{G_s \cdot \gamma_w}{1 + \frac{w \cdot G_s}{100}}
