MacGrid® AR are planar geogrid structures used for the reinforcement of asphalt roads. The geogrids are made from glass fibre or polyester woven together in a grid configuration, which is then coated.
They exhibit high tensile strength and high modulus of elasticity at low elongation. They offer a cost-effective solution for preventing reflective cracking within the upper asphalt layers of road pavements during resurfacing works.
MacGrid® AR G geogrids also include a geotextile backing to the grid structure. The textile is impregnated with bitumen to provide crack prevention with a waterproof membrane and improved bond between the asphalt layers.
