Due to its high shrink and powdered date seeds on the black cotton soil collected from swell property it is likely to develop cracks. When MIHAN, Nagpur. This soil had a plasticity index of 25 and high plasticity soils are treated, plasticity index was cohesive in nature. In order to determine whether the decreases having less affinity with water. In India, powdered date seed ash has an effect on the plasticity of soil, due to dearth of finance during road construction by liquid limit and plastic limit tests were conducted in the conventional method, there is need to go for suitable laboratory. Results show that plasticity index of soil method of low cost road development, followed by decreases with increase in percentage of admixture used. The results of this study show that with increase in step by step ground improvement techniques to percentage of admixture, plasticity index decreases. meet changing traffic demands. It has been noted Keywords: plasticity of soil, plasticity index, black that that there is very little research work done on cotton soil, organic admixture, liquid limit, plastic the effects of various organic admixtures on limit, plasticity of soil. Hence the main aim of this study is to examine the likely effects of ash of powdered date 1. INTRODUCTION: seeds on the plasticity of soil. Soil Stabilization is the method of enhancing the physical properties of soil. Stabilization can increase the shear strength of a soil and/or control the shrinkswell properties of a soil, and also improves load bearing capacity of a sub-grade as well as support pavements and foundations. Soil Stabilization along with ground improvement techniques can be utilized on roadways, parking areas, airports and many other situations where sub-soils are not suitable for construction. This process is accomplished using a wide variety of additives, including lime, fly-ash, and Portland cement. Other material by products can also be used such as coconut shell ash and, wood shavings ash etc have also been researched upon Black cotton © 2017, IRJET

2. MATERIAL: A) Material in use: 1. Soil: Expansive black cotton soil collected from the MIHAN area of Nagpur, Maharashtra was used. The basic index properties are as follows: 1. Liquid limit – 56% 2. Plastic limit – 31% 3. Plasticity Index – 25% 2. Organic admixture – ash of powdered date seeds: Date seeds in powder form were used. This powder has been later converted to ash by roasting. It was used in percentage by weight of soil at 15%, 20% and 25% by weight of soil. ISO 9001:2008 Certified Journal
