Polyester engineering fiber is a new crack resistant and reinforced material developed and produced specifically for asphalt concrete. It is a bundle shaped synthetic fiber made of 100% polyester synthetic material and processed through a unique process. It has advantages such as high strength, corrosion resistance, high temperature resistance, strong chemical stability, and strong adhesion with asphalt. When added to asphalt concrete, it can form a large number of fiber monofilament three-dimensional distribution after mixing, playing a role in reinforcement and bridging, Effectively improve the mechanical properties of asphalt mixtures and prevent cracking of asphalt concrete.

Main function: 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. This 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 and extending the service life of the road surface. It can effectively improve the tensile, compressive, and Application fields of shear and impact strength:

New asphalt concrete pavement surface layer

Old asphalt concrete pavement overlay (black+black)

Old cement concrete pavement cover (white+black)

Repair, cold repair, and joint filling of pavement defects

Asphalt surface layer for steel structure bridge pavement

Recommended dosage for use of airport runway and bridge deck waterproof layer: Based on the size of traffic flow, the recommended dosage of fiber (based on each ton of asphalt mixture)
