Polyester engineering fiber is a new crack resistant and reinforced material developed and produced specifically for asphalt concrete. Polyester engineering fiber is a bundle shaped synthetic fiber made of 100% polyester synthetic material and processed through a unique process. Polyester engineering fibers have advantages such as high strength, corrosion resistance, high temperature resistance, strong chemical stability, and strong adhesion to asphalt. Adding it to asphalt concrete and mixing it can form a large number of fiber monofilament three-dimensional distribution, which plays a role in reinforcement and bridging, effectively improving the mechanical properties of asphalt mixture and preventing cracking of asphalt concrete.

The main function of polyester engineering fiber is to improve the high-temperature stability of asphalt concrete, improve the low-temperature crack resistance of asphalt concrete, and improve the fatigue resistance of asphalt concrete. It can significantly improve the water stability, peeling resistance, wear resistance, and durability of asphalt concrete, effectively resist the generation of reflection cracks, thereby greatly improving the quality of the road surface, extending the service life of the road surface, and effectively improving tensile strength, compression resistance Shear resistance and impact strength.

Application field of polyester engineering fibers:

1: New asphalt concrete pavement surface layer

2: Old asphalt concrete pavement overlay (black+black)

3: Old cement concrete pavement cover (white+black)

4: Repair, cold repair, and joint filling of pavement defects

5: Asphalt surface layer for steel structure bridge pavement
