New Correlation System for Compressibility and Expansivity of Clays
Expansive soils undergo significant volume change with respect to the change in water content, which can be either in the form of swelling or in the form of shrinkage. The liquid limit of expansive soils may even vary from 100 to 500%. In general, all expansive soils have low shear strength, high compressibility and low permeability at very high initial water content. The same expansive clay would undergo high swelling, and shrinkage depends on seasonal fluctuation of water content in the wetting and drying process, respectively. Even though the compressibility and expansivity coexists, still there is no correlation between these two parameters. In this paper, an attempt is made to correlate compressibility with expansive characteristics of natural and synthetic soil whose liquid limit ranges from 62 to 389%.
