Atterberg Limits: A Quick Reference Guide - Gilson Co.

Swedish scientist Albert Atterberg was the first person to define the limits of soil consistency for the classification of fine-grained soils. Nearly 100 years later, his methods are still being used to determine the Liquid Limit, Plastic Limit and Shrinkage Limit of soils.

California bearing ratio - Wikipedia

The California Bearing Ratio (CBR) test is a penetration test used to evaluate the subgrade strength of roads and pavements. The results of these tests are used with the empirical curves to determine the thickness of pavement and its component layers. This is the most widely used method for the design of flexible pavement.

Atterberg limits - Wikipedia

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, a soil may appear in one of four states: solid, semi-solid, plastic and liquid.In each state, the consistency and behavior of a soil is different and consequently so are its engineering properties.

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.
