Atterberg limits

In plastic soils, the water contents (determined by standard tests) which define the boundaries between the different states of consistency of plastic soils. Also see liquid limit, plastic limit, shrinkage limit.

Other parameters, like the Atterberg limits or the decomposition time after Weissmann (Weissmann, Richwien 2003) cannot be determined in reproducible quality, so that different criteria may need to be developed.
Four surface soil samples were collected at depths ranging from 0-20cm using a stainless-steel hand auger within the dumpsite to determine engineering properties, in accordance with British Standards (Anon, 1990) which included moisture content, grain size distribution, porosity, permeability, plasticity and Atterberg limits.

These include natural moisture content, Atterberg limits, grain size analysis, specific gravity of solids, and cation exchange capacity (CEC).
The trend for lower correlations with texture as slope gradient decreases is clear (for soils) and is reinforced by the correlations with other, independently measured, but texture-related, properties, such as the Atterberg limits, the water contents at wilting point and field capacity, and the specific surface area of the soil.
Laboratory testing in accordance with current ASTM procedures including but not limited to grain-size analysis, Atterberg limits determination, natural moisture content and density determination, optimum moisture and density (Proctor) determination, swell/consolidation testing and water soluble sulfates content determination.
