A new conception of the plastic and liquid limits of clay.
1981
Faure A.
Soil compaction in the laboratory may show two particular points on the dry bulk density versus water content curve. At these points, dry bulk densities depend on the distribution and shapes and sizes of the soil particles and on the force or level of energy used in compaction. However, for a given force or energy level, water contents depend only on the kind of clay. It is shown that these two particular points correspond to Atterberg's plastic and liquid limits, each related to a specific level of energy. Thus the plastic index compares two characteristic water contents determined under identical experimental conditions.
