India’s growing economy needs extension of existing roads, new road routes and rural road developments. Flexible pavement is one of the most widely used highways all over the country. The properties of soil affect the stability and durability of the pavement. Now a days, various kinds of geotextiles are using as a successful application in soil stabilization for improving the subgrade soil properties. The application of geotextiles in structural facilities is mainly concentrated on the raising the strength of structure and also does not address the issue of sustainability of raw materials used. In India, for evaluating the stability of the soil subgrade CBR test is recommended as per IRC 37-2001 design code in designing the flexible pavements. In this work, natural geotextiles i.e. coir and bamboos are interfaced with soft subgrade from two different locations, to evaluate the performance of CBR values. Non-woven Coir and bamboos are interfaced individually at 75% depth from base and also in composite way. Comparison was done for different arrangements of natural geotextiles in subgrade sample. CBR value increases with increase in addition of geotextiles i.e., its value is higher for soil having composite geotextile (soil with non-woven coir + square arrangement of bamboo). It is economical as it can reduce the cost of construction as it reduces the total thickness of the pavement
