Determination of the Plastic Limit and Plasticity Index Purpose The plastic limit is that moisture content of a soil at which it becomes too dry to be plastic, used together with the liquid limit to determine the plasticity index which when plotted against the liquid limit on the plasticity chart enables the classification of cohesive soils. Apparatus Sample of Cohesive Soil Glass mixing plate ...
