(c) Determination of Shrinkage Limit • A further reduction in the moisture past the plastic limit, however brings about a state when with a decrease in moisture, the volume of the soil mass does not decrease but remains the same. • The sample changes from semi-solid to solid state at the shrinkage limit (boundary water content). Beyond this point the sample begins to dry up.

R-value (soils) - Wikipedia

The R-Value test measures the response of a compacted sample of soil or aggregate to a vertically applied pressure under specific conditions. This test is used by Caltrans for pavement design, replacing the California bearing ratio test. Many other agencies have adopted the California pavement design method, and specify R-Value testing for subgrade soils and road aggregates.

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.

Gravel - Wikipedia

Fine gravel: gravel consisting of particles with a diameter of 2 to 8 mm. Stone dust: fine, crushed, gravel from the final stage of screen separation, such that the gravel is not separated out from fine dust particles.
