Construction of roads
An effective geotextile is one that provides separation to preserve the aggregate base and maintain the designed structure and load-bearing capacity of the road. It helps prevent failure of the base and therefore the pavement by allowing the passage of water and preventing fine soil from mixing with the base. Light-use roads are usually constructed with thinner than required pavement thickness; these construction methods result in damage from the occasional passes of heavy delivery trucks or dumpsters, especially when the road is wet. Complete replacement of faulty asphalt or concrete sections using geotextiles to maintain the base and provide drainage is the most effective and permanent corrective action.
