Fiberglass geogrid is composed of glass fiber coated with the bitumen; these products possess the properties of high tensile strength in the machine directions. With lower elongation and excellent temperature resistance, fiberglass geogrid is widely used in the reinforcement of asphalt pavement, concrete pavement and roadbeds. Furthermore, compared to traditional use, fiberglass geogrid can deduce construction costs, extend road service life, and prevent deflection cracks, which can also be used to reinforce roadbeds and the soft soil basic bed for railways and water darns.
