This paper defines a maximum limit of compaction, which corresponds to the maximum density and the minimum moisture to be achieved in a state close to saturation, describes the test for determining that state, and, at the same time, proposes the plastic limit as the minimum limit for soil compaction in a state of saturation. Each conventional compaction test yields values for maximum density, optimum moisture, and saturation moisture. Taking into account the above-mentioned limits, two relative characteristics values are derived: the coefficient of saturation and the relative compactness, the latter being defined by the aforementioned relative density with regard to the ratio of voids between the defined limits, or, what amounts to the same thing, in more direct terms, by the saturation moisture in reference to the characteristic moistures of the above-mentioned limits. Experience with soil compaction using various procedures has shown that relative compactness is directly proportional to the compaction work in terms of soil weight and the area of the mold, as well as to the compaction moisture, and that relative compactness is null at the plastic limit. This paper states that verification of conclusions reached with regard to other soils and the correlation of characteristics of soils, including the compaction limit defined here, will permit an improvement of specifications in terms of relative compactness, thereby simplifying the on-site control of compaction during construction.
