PLASTICITY INDEX TEST REPORT

Scope

These procedures cover the determination of the liquid limit, plastic limit, and the plasticity index of soils. They are used extensively to correlate with engineering behavior such as compressibility, hydraulic conductivity, shrink-swell, and shear strength. Atterberg defined four possible states of consistency for soils: liquid, plastic, semi-solid and solid. The liquid limit divides the plastic and liquid states and is defined as the water content at which the soil flows to close a standard size groove when ...
