Note:
The Atterberg limits indicate the transition points where a soil’s physical behavior changes. The limits most commonly studied are the Plastic Limit, which identifies how much water a given soil can hold before it changes consistency between crumbly and plastic, and the Liquid Limit, where the soil changes consistency between plastic and liquid.
