Geogrids are widely used to reinforce asphalt. Extreme temperature fluctuations and (weight) loads sooner or later result in wear-and-tear, even in the case of high-quality material. Cracks and road traffic grooves then reveal the damge. For this reason, the structure below the asphalt layer is of decisive importance. If concrete is covered, asphalt reinforcement grids ensure that the gaps between the concrete panels do not show througth to the above asphalt layer. In railroad construction, geogrids are basically used for reinforcing unstable base layers, whereby the material benefits from the extreme tenacity of the used yarns. The central element of geogrid manufacturing is the weft-inserting machine with the subsequent coating process. The weft-inserted fabric is coated with a coating material (i.e. plastisol or a bitumen blend) directly after it has been formed and then wound up into rolls.
