Polyester fiber is a new anti cracking and reinforcing material specially developed and produced for reinforcing asphalt concrete. It is a bundle shaped synthetic fiber made of 100% polyester synthetic material and processed by unique technology. It has the advantages of high strength, corrosion resistance, high temperature resistance, strong chemical stability and strong adhesion with asphalt. When added into asphalt concrete, it can form a large number of three-dimensional fiber monofilament after mixing In order to effectively improve the mechanical properties of asphalt mixture and prevent the cracking of asphalt concrete, cloth plays the role of reinforcement and bridge.
