WebbPlasticity index shows the size of the range of the moisture content at which the soil remains plastic. Usually plasticity index depends on the amount of clay present in the soil. A high value of PI indicates an excess of clay in the soil and that results in greater plasticity of that soil. If soil’s plasticity index is small that shows soil ... WebbThe plasticity chart for fine-grained soils (see Table 14) is divided into six sections by the oblique line A drawn so that the PI = 0.73 (LL - 20) and two vertical lines drawn at LL = 30 percent and LL = 50 percent. Each section of the chart characterizes a group of soils with well-defined mechanical characteristics. greater cincinnati catholic youth basketball
