The stability of any pavement depends upon the stability of its subgrade soil. Subgrade governs the performance, life span and effectiveness of the pavement. The entire load coming over the pavement is ultimately borne by the subgrade. Thus, the subgrade plays a very important role in the pavement design. Now-a-days, many techniques are used to stabilize the subgrade soil, use of natural fibres being one of them. Natural fibres are cheap, easily available and eco-friendly. A study was conducted to investigate the influence of randomly oriented natural fiber on soil strength parameter. Three type of natural waste fibres i.e., coir, jute and rubber fibers with varying doses (w/w) were used. Laboratory tests were carried out to evaluate the reinforcing effect of these natural fibres on the strength of the subgrade soil. Characterization of soil was carried out by grain size distribution and soil classification. For stabilized soil, the Atterberg limits, Unconfined Compressive Strength test and California Bearing Ratio tests were conducted in accordance with the standard procedures for different combination of soil and natural fibres. Among the natural fibers used, jute fibre gave best improvement in strength of the subgrade soil. 1% w/w of jute fibre was found to be optimum ratio among the dose tried. 1.86 times increase in CBR value and 2.07 times increase in UCS was found compared to the virgin soil.
