For every soil, there is an optimum amount of moisture for which it can experience its maximum compression. In other words, for a given compactive effort, a soil is reaching its maximum dry unit weight (γ d,max), at an optimum water content level (w opt). The compressibility of a relatively dry soil increases as water is added to it.
