Soil stabilization is the process which involves enhancing the physical properties of the soil in order to improve its strength, durability etc. by blending or mixing with additives. The strength of subgrade soil or road foundation could influence the design of road pavement structures. Flood can be one of the causes of weakened subgrade and consequently road damages. Since the condition of subgrade layer is critical in the road pavement stability, a preliminary study was carried out to ascertain the use of CFF In stabilization mechanism in road subgrade. This study was conducted based on expansive soil ie,clay. California Bearing Ratio (CBR) test was conducted on the various categories of soaked conditions to determine the strength of subgrade soil with and without mixing of CFF fibers. It can be concluded that CFF can be used to increase or maintain the strength of subgrade soil from the inundation effect.
