The geosynthetic products most commonly used in roadway systems include geotextiles (woven and non-woven) and geogrids (biaxial and multiaxial), although erosion-control products, geocells, geonets (or geocomposite drainage products), geomembranes, GCL and light weight geofoams have also been incorporated in a number of applications. These various types of geosynthetics can be used to fulfil one or more specific functions in a variety of roadway applications.

Geotextiles

Geotextiles extend the service life of roads, increase their load-carrying capacity, and reduce rutting. Geotextiles perform three basic functions in stabilizing aggregate sections: separation, drainage and reinforcement.

Geotextiles provide a separation layer between the aggregate and the sub grade soil, to prevent migration of fines and thus indefinitely preserve the original aggregate structural thickness.
