Polyester fiberglass cloth guides the innovation of asphalt pavement, using glass fiber and polyester fiber as the main raw materials and made by wet process technology. Glass fiber and polyester fiber are widely used waterproof and reinforcing materials both domestically and internationally. Polyester fiberglass cloth embodies the excellent characteristics of both fibers: GF strength, heat resistance, aging resistance, and water resistance; The flexibility of PET has resulted in a new material that combines rigidity and flexibility, overcoming their respective shortcomings of brittleness and heat resistance.

Polyester fiberglass cloth is a new type of composite geosynthetic material developed after geotextiles, geogrids, and strip polymers, which has good compatibility with asphalt mixtures. Engineering practice has shown that fiberglass grating does not have waterproof function, and its mesh can form an interlocking effect with asphalt mixture. However, it is difficult to fix during use and is prone to expansion, which affects the normal paving and reinforcement of asphalt mixture; Geotextile can prevent water infiltration, but its strength and creep resistance are poor when the temperature of hot asphalt mixture paving exceeds 160 ℃, and it cannot exert the effect of reinforcement and crack resistance; And polyester fiberglass cloth overcomes the shortcomings of both. It can effectively deal with road cracks and water damage to bridge decks and road surfaces.
