Soil is Basic Foundation for any Civil Engineering Structures and Soil Stabilizing can be defined as the modification of soil property Chemical or Physical Means in order to enhance the Engineering quality of soil the property of these clay soil in general is that they very hard when in dry state but they lose all of their strength when in wet state, In light of this property of clay soil these soil pose problem worldwide that serve as challenge to overcome for geotechnical engineers. One of the most important aspects for construction purposes is soil stabilization, which is used widely in foundation and road pavement constructions; this is because such a stabilization regime improves engineering properties of the soil, such as volume stability, strength and durability. In this process, removal or replacing of the problematic soil is done; replacement is done by a better quality material, or the soil is treated with an additive. In the present study using of Fly ash is obtained from Geotechnical Laboratory at NIT Trichy, Clay soil obtained from sindhulipu village in Coimbatore District, Lime is obtained from rasakaplayam lime plant in pollachi and coir fiber is obtained as locally available cheap, eco-friendly Natural material, which can be burned into ash. Hence the cost of stabilization may be economical by replacing good proportion of stabilizing agent using Fly ash, lime and Coir ash, where the result are compared for the two samples likely F.A+ Lime + Soil and F.A+ Lime + C.A + Soil and are observation are made by replacing different proportion to change Maximum Dry Density (MDD) Optimum moisture content (OMC), Unconfined compressive strength (UCS) and unsoaked California Bearing Ratio (CBR) are values Concluded that for various works in civil engineering such as Sub grade for road construction and foundations etc.,
