These geogrids perform a reinforcing function and are used in layers of asphalt concrete surfacing for improvement of transport and operating indicators of roads, for extension of their life and retardation of appearance of different defects on the surfacing (cracks, corrugations, ruttiness, etc.).

Reinforced plastics are composites on the basis of a polymer binding substance (matrix) and a reinforcing filler of a fibre pattern. Heat-convertible resins and engineering thermoplastics are used as binding substances. Inorganic and organic fibre materials in the form of monofilament yarns, complex yarns, short (discontinuous) fibres, tows, fabrics, felts and single crystal filaments serve as fillers.
