Abstract: Soil is the basic foundation for any civil engineering structures. It is required to bear the loads without failure. In some places soil may be weak which cannot resist the oncoming loads in such cases soil stabilization is needed, The clay often is weak and has no enough stability in heavy loading. Stabilization is being used for a variety of engineering works, the most common application being in the construction of road and airfield pavements, where the main objective is to increase the strength or stability of soil and to reduce the construction cost by making best use of locally available materials. With ongoing rise in use of motor vehicles hundreds of millions of tyres are discarded each year throught the world. Many are added to existing tyre dumps or landfills and a significant number for recycling into a useful products.Since highway construction requires large volumes of materials, highway agencies have been encouraged to participate in the recycling effort. Recovering these materials for use in construction requires an awareness of the properties of the materials and the limitations associated with their use. Use of shredded tyres in geotechnical engineering for improving soil properties has received great attention in recent times. Present an attempt has been made through laboratory study to understand the potential of shredded tyres in soil stabilization, which help not only in soil stabilization but also in utilization of waste. Shredded tyres having size 5mm, 10mm, 30mm and 50mm after removing steel belting are used. This paper presents the investigation of clay soil stabilized with shredded tyre. It is found that unconfined compressive strength of clay-shredded tyre mixture were found to be between 0.23 and 0.37kg/cm2. Permeability of clay –shredded tyres is higher compared with that to clay alone. Less swelling and swelling pressure observed on addition of shredded tyres compared with clay alone.
