Abstract

In the field of Geotechnical Engineering, elastic properties of soil and soil-lime mixtures are generally analysed with optimum moisture content. But, during compaction with the increase in water content from the dry side of optimum to the wet side of optimum, the structure of clay particles changes from a flocculated to disperse structure. Therefore, in this paper an attempt was made to study the effect of moulded water content on black cotton soil and lime treated black cotton soil at a dry side of optimum, near and wet side of optimum to investigate the elastic properties (i.e. Poisson's ratio and modulus of elasticity). The different percentages of lime used during the experimental work are 3%, 6% and 9%. Image analysis technique was used for measuring the change in lateral dimensions of the soil specimens during the process of uniaxial static loading produced by Unconfined Compression (UCC) testing machine. Then the obtained results have been used for computing Poisson's ratio. The results showed that with the decrease in moulded water content from wet to dry side of optimum, the modulus of elasticity of black cotton soil increases. But in the case of lime treated black cotton soil, with the increase in lime content and curing time, the moulded water content at the wet side of optimum gives higher modulus of elasticity compared to that of dry side of optimum.
