New geogrid increases life of pavement
Tech Glass Geogrid is used as an interlayer over distressed pavement, or within the overlay for reinforcement, increasing the overall life of the pavement. It retards the development of reflective cracks by absorbing stresses that arise from damaged pavement. A series of glass fiber strands are knitted into a grid and coated with modified polymer bitumen. Each glass strand has very high tensile strength and modulus of elasticity at low elongation that provides additional support to resist the migration of reflective cracks.
