Once there is a change in a place, type of soil also get changes. Along with soil type the properties of soil also changes. For any kind out of construction we require stable foundation in the form of firm strata. This can be available naturally if hard rock encountered below the soil. But this condition can not be possible at every site. Hence stability of foundation soil is the major work in front of construction industry. Research shows lot of interest and many methods were found out for the stabilization of soil. Soil Stabilization by using cement and lime was the most ancient method which was commonly adopted all over the world. But it is found out that this will prove costly and time consuming. In this study the effect of inclusion of various types of fibres on unconfined compressive strength of clayey soil was studied. The fibres used were natural fibre, plastic fibre, polypropylene with different fibre contents and length. The fibre percentages were varied from 0% to 2%. The fibre length and fibre content are found to play important roles in the strength of fibre reinforced soil. Furthermore, it was observed that the unconfined compressive strength of soil sample taken for study increased by inclusion of fibres. Conclusions were obtained from this investigation that the inclusion of randomly distributed fibres significantly improved the unconfined compressive strength of clayey soil. Increase in fibre content decreases MDD and increases OMC. Optimum percentage of fibres was identified from the carried out study. Use of optimum quantity of fibre will reduce the cost of project. Results shows that soil stabilization by fibres will effects on the life cycle of the project ultimately project deration reduces.
