The Atterberg test was developed by Albert Atterberg and Arthur Casagrande. It is used to determine the Liquid Limit (when soil behaves as a liquid) and Plastic Limit (when soil is no longer cohesive); the difference between these two is known as the Plasticity Index.
While this video is not 100% true conformance to ASTM, it demonstrates the techniques and methods used, and should give a basic understanding of what the test is and how it works.
