Soil is a base of structure, which actually supports the structure from beneath and distributes the load effectively. If the stability of the soil is not adequate then failure of structure occurs in form of settlement, cracks etc. Expansive soil also known as black cotton soil is more responsible for such situations and this is due to presence of montmorillonite mineral in it, which has ability to undergo large swelling and shrinkage. To overcome this, properties of soil must be improved by artificial means. Soil reinforcement technique is one of the most popular techniques used for improvement of poor soils. The improvement of sub-grade has always been significant aspect in highway and geotechnical engineering fields. To strengthen the subgrade soil, the use of natural Jute fiber is advantageous because they are cheap, locally available, and biodegradable. In this paper the soil sample was compacted at its maximum dry density corresponding to its optimum moisture content in the Laboratory California Bearing Ratio (CBR) mould with and without natural Jute fiber. Natural Jute fiber sheets equal to the plan of CBR mould diameter were placed at various layers to investigate its behaviour on CBR value.
