Abstract:

The change of density and different saturation conditions on the Unconfined Compressive Strength (UCS) of soil are analyzed. The present study is aimed at determining the influence of the specific gravity, optimum Moisture Content, and maximum dry density obtained from both the Standard Proctor Test and the Modified Proctor Test on the UCS of black cotton soil and yellow soil for Navsari and Surat, cities located in the South Gujarat region in western India. The results of UCS Test showed different saturation conditions at each density. The graph showed an upward slant at the Standard Proctor density from 90% to 100% saturation.

Keywords: Unconfined Compressive Strength, density, saturation, Moisture Content, compaction
