Which of the following Atterberg limits is used to classify soil plasticity?

The classification of soil plasticity relies heavily on both the Liquid Limit and Plastic Limit, as these two parameters define the range of moisture content within which the soil exhibits plastic behavior. The Liquid Limit represents the moisture content at which soil transitions from a plastic state to a liquid state, which is critical in determining how the soil behaves under different moisture conditions. It helps in assessing the soil's ability to be molded and its susceptibility to deformation when saturated. The Plastic Limit, on the other hand, is the moisture content at which the soil transitions from a plastic state to a semi-solid state. This limit indicates the moisture content below which the soil behaves more like a solid and loses its plastic characteristics. By using both these limits, engineers and soil scientists can establish the Plasticity Index, which is the difference between the Liquid Limit and the Plastic Limit. This index serves as a key indicator of a soil's plasticity characteristics, allowing for the classification of soil types. Therefore, understanding both limits is essential to effectively classify and work with soil materials in various engineering contexts.
