REAPPRAISAL OF NON-PLASTIC SOILS

Description

In many cases, the liquid limit of the soil can be determined using the fall cone method, yet the soil is reported as non-plastic. This study suggests that if the liquid limit of the soil can be determined using the fall cone method, then soil possesses some plasticity which cannot be quantified using a conventional method of thread rolling. In this paper, the plasticity index of the alleged non-plastic soil is computed using a mathematical model.
