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 … Visa mer Shrinkage limit The shrinkage limit (SL) is the water content where further loss of moisture will not result in more volume reduction. The test to determine the shrinkage limit is ASTM International D4943. … Visa mer The values of these limits are used in a number of ways. There is also a close relationship between the limits and properties of a soil such as compressibility, permeability, … Visa mer 1. ^ "Brief history of Swedish Soil Mechanics".

Because higher plasticity soils exhibit this characteristic over a much wider range of moisture contents than do low plasticity soils, the Atterberg Limits are typically the basis on which plasticity determinations are made.
