Liquid Limit & Plastic Limit (Plasticity Index)

This test involves determining the plastic limit and liquid limit of the soil sample. The plastic limit is the moisture content at which the soil changes from a plastic to a semisolid state, while the liquid limit is the moisture content at which the soil changes from a plastic to a liquid state. By determining the Atterberg limit, it is possible to assess the plasticity of the soil and its suitability for various construction applications.
