Atterberg Limits Liquid Plastic Amp Shrinkage Limit

Atterberg Limits and Indices. Atterberg defined the boundaries of four states of soil in the terms of limits. A fine-grained soil exists in different states depending on the amount of water in the soil system. The water content at which the soils change from one state to the other is known as consistency limits or Atterberg limit.
