Maximum Dry Density of Soil and Optimum Moisture Content Test

When the soil particles are lubricated with the increase in the water content, the soil particles will be densely packed resulting in increased density. Now beyond a limit (OMC) the addition of water will not bring a change in dry density or will decrease the dry density. The graph represents a zero-air void or 100 % saturation line.
