Geogrids IYSGFG-Highway consist of two systems of rovings or complex yarns sewn together with a third (sewing) yarn and impregnated with complex mixtures based on binding latexes having a good adhesion with bituminiferous materials (asphalts).
|
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.).
