Clay soil is highly typical soil because it undergoes differential settlement, poor shear strength and high compressibility .For this the most effective and economical methods to improve clayey soil is addition of stabilizing agents such as lime or rice husk ash (RHA). It is essential to improve load bearing capacity of clayey soil, for taking more load. In this study, highly plastic clay was stabilized by using lime and rice husk ash (RHA).The present investigation has been carried out with agricultural waste materials like Rice Husk Ash (RHA) and cheaply available lime is mixed with clayey soil improvement of weak sub grade in terms of compaction and strength characteristics. In this investigation lime and rice husk ash (RHA) is added by weight of soil. The main objective of this investigation is to access cheaply availability of lime and rice husk ash for improving engineering property of clayey soil for making capable of taking more load form structure to foundation.In modern-day technology, lots of chemical stabilizers are frequently practiced; however these are often high-priced and unhygienic in terms of environmental sustainability. The prevailing investigation has therefore been completed by using Rice Husk Ash (RHA) and Lime. RHA is an agricultural waste fabric of Rice production which commonly increases environmental pollutants. When we combined RHA and Lime collectively with virgin soil it makes some improvement on geotechnical properties of the virgin soil.
