PAN Fiber for Asphalt Pavements Reinforcement | PIONEER®
Premium PAN Fiber Solutions for Fiber-Reinforced Asphalt Mixtures
With exceptional thermal stability, high tensile strength, and superior bonding with asphalt binder, HGM® PAN enhances resistance to thermal cracking, rutting, fatigue, and deformation—extending pavement service life under heavy traffic and fluctuating temperatures.
What Is HGM® PAN Asphalt Fiber?
HGM® PAN is a specially engineered polyacrylonitrile fiber designed as a reinforcement additive for hot mix asphalt. It forms a three-dimensional micro-reinforcement network within the asphalt matrix, improving mixture stability, binder retention, and load distribution.
Compared with other synthetic fibers, PAN fibers offer outstanding heat resistance, enabling superior performance in high-temperature mixing and compaction environments.
Key Performance Enhancements:
-
Improved anti-cracking and thermal crack resistance
-
Higher stability during high-temperature asphalt mixing
-
Reduced drain-down in SMA and OGFC mixtures
-
Enhanced durability and fatigue life
-
Improved resistance to rutting and deformation

How HGM® PAN Reinforces Asphalt Mixtures
1. Three-Dimensional Fiber Network
Enhances tensile strength and distributes load more evenly through the asphalt matrix.
2. Improved Cohesion and Stability
Fiber prevents binder migration and reduces drain-down during production and paving.
3. Increased Resistance to Rutting and Deformation
Improves resilient modulus and mixture stiffness without compromising flexibility.
4. Enhanced Fatigue Life
Fiber-reinforced asphalt withstands repeated traffic loads more effectively.

FAQ
PAN fiber is used to reinforce asphalt mixtures by improving resistance to cracking, rutting, and fatigue damage. It enhances the durability and performance of fiber-reinforced asphalt concrete (FRAC) in high-stress road applications.
PAN fibers disperse uniformly within the asphalt mix, forming a 3D reinforcement network that stabilizes the binder and aggregate structure. This reduces deformation, improves flexibility, and extends pavement service life.
The recommended dosage is 1–3 kg per ton of asphalt mix, depending on traffic load, climate, and pavement design.
Yes. PAN fibers can be added directly during the mixing stage and require no modifications to conventional hot mix or warm mix asphalt production.
No. When mixed properly, PAN fibers maintain workability and compaction efficiency while enhancing fiber-matrix bonding.
