Definition of Maximum Dry Unit Weight

The unit weight in the dry condition is calculated using relation given below. Here, the term γ d is the unit weight at dry state, γ is bulk unit weight and w is moisture content it is expressed in percent. The maximum value of dry unit weight varies with characteristics of the soil and its type. This value is most important in the compaction ...
