This paper shows that a semilog plot of optimum dry density versus compaction effort in energy per unit volume gives essentially a straightline relationship. The slope of this line varies with the plasticity and other related properties, the slope becoming steeper as the plasticity increases and the soil becomes more difficult to compact. It is proposed that laboratory compaction tests, conducted at three compaction efforts and plotted as described, be used as a basis for a classification scheme. It is suggested that such data be used for guidance in establishing compaction requirements for different soils and for predetermining the amount of compaction effort necessary to achieve a desired field density.
