Atterberg Limits Test, What is the Purpose? - Gilson Co.

Atterberg Limits Test Procedure: For all the Atterberg limits tests, soil samples consist of material passing a No. 40 (425µm) test sieve and are prepared for each test using wet or dry methods described in the standards. Moisture in Test specimens is adjusted by adding water, mixing with a spatula, and allowing to condition for at least 16 hours.

Atterberg Limits - Liquid, Plastic Shrinkage Limit ...

Atterberg Limits and Indices. Atterberg defined the boundaries of four states of soil in the terms of “limits”. A fine-grained soil exists in different states depending on the amount of water in the soil system. The water content at which the soils change from one state to the other is known as consistency limits or Atterberg limit.

Proper characterization of a dense-graded aggregate base/subbase material should include both quality and strength aspects. Gradation, passing the No. 200 sieve (smaller than 0.075 mm) fines content, and Atterberg limits for plasticity index (PI) are the most important properties that affect the quality and longevity of aggregates used as unbound layers in flexible pavement applications.
