Atterberg Limits

Atterberg Limits are tests used to measure how clay and fine soils behave in terms of moisture content. They determine the soil’s plasticity, or how it can be shaped without cracking or crumbling. The limits include the Liquid Limit (when soil transitions from plastic to liquid), the Plastic Limit (when soil begins to crumble when rolled), and the Shrinkage Limit (when soil stops shrinking upon drying). These tests help engineers understand soil stability, suitability for construction, and how it will respond to moisture changes, ensuring safe and effective foundation and infrastructure design.
