Coir geotextiles due to inherent properties like highest strength among all the natural fibres and high water absorption with maximum swelling of only 5% and very high extensibility of 30% have been found to be the ideal replacement of the geosynthetics normally used in the construction of roads to stabilize the sub grade agrarian soils. Provide a physical barrier to the intermixing of the aggregate and sub grade soil, Restrain the aggregate sub-base from downward and lateral movement in the rut, Provide sufficient friction to limit lateral sliding of the aggregate.
