Atterberg Limit On Gravel

Soil Engineering: Common Terms and Definitions

Atterberg Limits – the results of three tests, the liquid limit test, the plastic limit test, and the shrinkage limit test (only the first two are commonly performed). These tests are a measure of the plasticity of a soil. Gravel – rounded or semirounded particles of rock that pass a 3-in. (76.2-mm) sieve and are retained on a No.4 U.S

Liquid Limit (Cone Penetrometer Devices)

The cone penetrometer apparatus is used to determine the moisture content at which clay soils pass from a plastic to a liquid state and it is used also for the determination of undrained shear strength. Two versions available: the standard 22-T0029/D and the semi-automatic 22-T0029/E. The penetrometer has a cast iron base with leveling screws

The Atterberg limits are empirical indices of the critical water contents defining mechanical states of soil-water mixtures between the semisolid state and plastic state (the plastic limit or w P), and between the plastic state and liquid state (the liquid limit or w L).They reflect semiquantitatively a fine-grained soil's ability to resist external loading.
