Atterberg Limits – Soil Lab Modules
It is advisable to test the liquid limit first. In coarse textured soils it is usually difficult to control water content for the liquid limit test and those soils may not even have a plastic limit. Liquid Limit is the soil water content where the soil changes from a plastic to a viscous (liquid) state. Liquid limit is …

Atterberg's Limits Soil Classification - Liquid Limit ...
A. Atterberg defined the boundaries of four states in terms of "limits". A fine-gained soil can exist in any of several states; which state depends on the amount of water in the soil system. When water is added to a dry soil, each particle is covered with a film of adsorbed water. If the addition of water is continued, the thickness of the water film on a particle increases.

Atterberg Limits, ASTM D4318 - Humboldt Mfg
Atterberg limits is a basic measure of the critical water content of fine-grained soils. These tests include shrinkage limit, plastic limit, and liquid limit, which are outlined in ASTM D4943. Depending on the water content of a soil, it may appear in four states: solid, semi-solid, plastic and liquid.
