WebThe plastic limit of a soil is the moisture content at which soil begins to behave as a plastic material. At this water content (plastic limit), the soil will crumble when rolled into threads of 3.2mm (1/8in) in diameter. In this article test methods used for determination of soil plastic limit in accordance with ASTM D4148 will be presented.

WebThe Atterberg limits [shrinkage limit (SL), plastic limit (PL) and liquid limit (LL)] describe the physicomechanical behavior of soils and thus are crucial for civil and agricultural applications. The Atterberg limits are a basic measure of the critical water contents of a fine-grained soil: its shrinkage limit, plastic limit, and liquid limit. Depending on its water content, soil may appear in one of four states: solid, semi-solid, plastic and liquid. In each state, the consistency and behavior of soil are different, and consequently so are its engineering properties. Thus, the boundary between each state can be defined based on a cha… WebA comparability is the liquid limit are a sample before and after oven-drying can, therefore, breathe used as a qualitative appraise of the organic matter show are one soil.
