Lime stabilization of expansive soils has been one of the oldest and most effective methods for improvement of poorly performing swelling soils. Addition of lime to expansive soils result in reduction in plasticity and swellshrink characteristics and improves strength of the stabilized soil [22]. However, a sift through literature reveals that lime stabilization has been found wanting under certain soil conditions like sulphate rich environments, conditions of alternate wetting and drying, freezing and thawing to name a few. In the recent years, a lot of focus has been put on the reuse of solid wastes in various streams of Civil Engineering for their effective management. Soil stabilization is one such avenue for effective reuse of solid wastes [16]. There have been a lot of investigations on the utilization of different types of solid wastes in soil stabilization. However, an effective replacement for lime is yet to be found despite its limitations. One pragmatic way of finding an effective replacement for lime is to adopt solid wastes similar to lime in chemical composition. Lime is an umbrella term adopted for quick lime (CaO), hydrated lime (Ca(OH)2) and carbonate lime (CaCO3). Egg shell waste is one such waste material whose chemical composition is very similar to lime. The targeted egg production in India for the year 2020 is 106 billion [14]. Based on the calculation
