Effect of Moisture Changes on Mechanical Properties of a Lime-Treated Soil with Organic Matter

The behavior of soil-additive has previously been studied and lime is one of the additives used. However, the effect of lime on permanent deformation has not been extensively studied under drying and wetting conditions. The authors in this study show the effect on mechanical behaviour of a lime-stabilized soil (with high organic matter content). Tests such as unconfined compressive strength, resilient modulus and permanent deformation were studied under different water content conditions. The results indicated that while the mechanical properties of the natural soil are quite susceptible to changes in water content, the properties of the lime-stabilised soil appear to remain essentially constant. It was also observed that permanent deformation of the lime-treated soil remained quite low at values below 0.2% and unconfined compression strength for this soil appeared to remain at 1050 kPa, regardless of the water content.
