The development of any country mainly depends on the transport system, trading etc. One of the major transport systems to connect all the villages and cities are roads. The construction of roads in most of the places across the world faces major problems due to weak sub grade soil. Due to the presence of mineral called montmorillonite in the clay, it exhibits large swelling and shrinkage under the wet and dry conditions and due to which the vertical movement is experienced in the pavement and there by the failure of pavement takes place. The total load coming on to the pavement should be properly dispersed through the sub grade. The poor performances of the subgrade soil can be improved by adding some materials or fibres in it. Use of waste material and natural fibre for improving soil property is advantageous because they are cheap, locally available and eco-friendly. In this study, the stabilizing effect of Natural fibre (coconut coir) on soil properties has been studied. An experimental study is conducted on locally available i.e. clayey soil mixed with varying percentage of coir fibre. The percentage of coir fibre by dry weight of soil is taken as 0%, 0.50%, 0.75%and 1% and corresponding to each coir fibre content, Standard Proctor and Unconfined compression tests are conducted in the laboratory. Tests result indicates that shear strength value determined from unconfined compression Test of soil increases with the increase in fibre content. The addition of 0%, 0.5%, 0.75% and 1% by dry weight of soil of randomly distributed coconut fibre increases the shearing strength of the soil sample respectively. Adding of coconut coir fibre results in less thickness of pavement due to increase in strength 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 natural fibre changes the brittle behavior of the soil to ductile behavior.
