In fast growing today's world, development of new construction materials, new technique and industrial waste is being given the top priority. This is important for conservation of scarce resources and for achieving maximum disposal of waste. Use of Coconut Fibre for improving soil property is advantageous because they are cheap, locally available and eco-friendly. In this study, the stabilizing effect of Coconut Fibre on expensive soil properties has been Experimental studied. Keeping this in view an experimental study is conducted on Expensive soil mixed with varying percentage of Coconut fibre. Soil samples for California bearing ratio tests are prepared at its maximum dry density corresponding to its optimum moisture content in the CBR mould without and with Coconut fibre. The percentage of Coconut fibre by dry weight of soil is taken as 0.25%, 0.50%, 0.75% & 1% and corresponding to each Coconut fibre content un-soaked and soaked CBR tests are conducted in the laboratory. Tests result indicates that both un- soaked and soaked CBR value of soil increases with the increase in Coconut fibre content. Soaked CBR value increases from 3.9 % to 8.6 % and un-soaked CBR value increases from 8.1 % to 13.2 % of soil mixed with 1% Coconut fibre. Adding of coconut fibre results in less thickness of pavement due to increase in CBR of mix and reduce the cost of construction and hence economy of the construction of highway will be achieved. This is because of composite effect of Coconut fibre changes the brittle behavior of the soil to ductile behavior
