Transportation infrastructure development is crucial to a country's overall growth. Roads are one of the most essential routes of transportation in the world, and they play a crucial part in a country’s economic and social development. Unpaved roads are typically utilised for low traffic flow and serve as access roads; they are also known as village roads. Unpaved roads serve a critical role in the rural region economy and the resource sectors of agricultural and resource-rich countries. a method is required that either removes the requirement for good-quality aggregate or needs the use of only a small amount of the such material while still providing adequate road performance. Geosynthetics have been utilised to improve unpaved roads on basis of soft subgrades and to lengthen their service life. By adding reinforcement, the aggregate layer thickness required for a given traffic volume can be reduced, or the traffic volume can be raised for a given aggregate layer thickness. Due to its high lignin concentration, coir fibre is robust and degrades slowly when compared to other natural fibres (Rao and Balan, 2000). When embedded in the fill material, coir geotextile creates good interface friction with granular fill, which can cause tensile stress in the reinforcement.
