Atterberg Limits of Soil Classification - Atterberg Test

A. Atterberg defined the boundaries of four states in terms of "limits". A fine-gained soil can exist in any of several states; which state depends on the amount of water in the soil system. When water is added to a dry soil, each particle is covered with a film of adsorbed water. If the addition of water is continued, the thickness of the water film on a particle increases.
