Atterberg limits of soils are very important in construction. Water content drastically influences properties of fine-grained soils. ... The soil will remain in this plastic state until its liquid limit is exceeded, which causes it to transform into a viscous liquid that flows when jarred.

What is the purpose of Atterberg limits?

Atterberg limits tests establish the moisture contents at which fine-grained clay and silt soils transition between solid, semi-solid, plastic, and liquid states.

Why is the plastic limit important?

Importance of Plastic Limit Test of Soil

The value of the plastic limit is used to classify the fine-grained soils and evaluating the activities of clayey soil. 2. It indicates the toughness index of soil. ... It gives an idea regarding the consistency of soil.
