Abstract: There is many factors that influence the failure of pavement; soil erosion in shoulders is one among them. Heavy rainfall regions like Dhakshin Kannada, shoulder erosion is one of the major considerations which is greatly affecting the life of road structure and also affects the road safety. In the present study the effect of addition of polypropylene fibers to the shoulder soil with different dosages are studied. Soil samples were collected from roads which are affected by shoulder erosion. A series of test were conducted to study the effect of fibers on California bearing ratio and shear strength of soil. From the test results it is observed that, the addition of polypropylene fiber to the soil with different dosage results insignificant improvement of strength properties. Hence addition of polypropylene fiber is recommended to use in stabilizing shoulder soil to reduce erosion and to ensure safety
