TechGlass Geogrid is composed of a series of glassfibre strands knitted into a grid structure with uniform aperture sizes and coated with modified polymer bitumen. Each glass strand has remarkably high tensile strength and high modulus of elasticity elongation which provides additional support to resist the migration of reflective cracks by transferring the stresses horizontally to dissipate them. Tech Glass Geogrid has two types of products: Tech Glass 100 and Tech Glass 50.
Tech Glass 100 is a high bi-directional strength product offering a 100 kN/m ultimate tensile stability along both the longitudinal and transverse direction. This is an ideal product for use over the whole pavement surface for pavements with a heavy traffic load and shear load.
Tech Glass 50 is a moderately strong bi-directional strength product offering a 50 kN/m ultimate tensile stability along the longitudinal and transverse directions.
