Polyester Staple Fiber Introduction:

Our company develops and produces polyester staple fiber, a new asphalt concrete crack reinforcement. Made from polyester (PET) with functional additives, it's produced via melt extrusion, high-speed spinning, high-magnification stretching, surface treatment, and precision cutting.
Featuring a cross-bundled monofilament structure, the fiber forms strong interactions with asphalt matrix (bitumen and mastic) when mixed into concrete. Theoretical analysis and practical applications show it modifies asphalt, enhances toughness, and provides reinforcement/bridging effects. This significantly improves rutting and low-temperature crack resistance while extending fatigue life.

Polyester Staple Fiber Characteristics:

PropertiesSpecific Functions
Prevent asphalt concrete crackingInhibits crack formation, resists reflective cracking from base cracks, enhancing pavement integrity.
Improve high-temperature stabilityEnhances deformation resistance in heat, reducing rutting/shoving and prolonging service life.
Enhance low-temperature crack resistanceImproves cold flexibility, reducing shrinkage cracking from temperature drops and freeze-thaw damage.
Improve peel resistanceStrengthens asphalt-aggregate adhesion, reducing film stripping from water/loads to enhance durability.
Enhance fatigue resistanceDistributes stress, delays fatigue crack initiation/propagation, improving cyclic load capacity.
Improve water stabilityReduces water erosion, minimizing raveling/pothole risks and enhancing water resistance.

Polyester staple fiber application:

1.New asphalt concrete pavement: Applied in new road construction to enhance pavement performance by improving 

   durability and load resistance.

2.Old pavement overlay: Used as a renovation layer to inhibit reflective cracks and strengthen structural stability in 

   aged asphalt surfaces.

3.Low-temperature crack resistance: Enhances asphalt concrete’s ability to withstand cold-induced shrinkage, 

     reducing cracking risks in frigid environments.

4.Pavement defect repair: Fixes cracks, potholes, and flaws, boosting the durability and load-bearing capacity of    

    repaired sections.

5.Bridge deck asphalt: Installed on bridge surfaces to strengthen fatigue and water damage resistance, ensuring long-

   term structural integrity.

6.High-strength concrete reinforcement: Added to fine aggregates to improve crack resistance and structural 

     wholeness in high- performance concrete.

PACKING: 1.0kg / small bag, 20 or 25kgs a plastic woven bag, about 12mts/1x20`gp

                    Also can be made as per customer`s request
