Polyester Fiber Reinforcement for Asphalt Pavements | PIONEER®
Premium Asphalt Fiber for Fiber-Reinforced Asphalt Mixtures
What Are Polyester Fibers for Fiber-Reinforced Asphalt Pavements?
PIONEER® HGM® PET is a premium modified polyester fiber designed specifically for asphalt reinforcement.
Made from 100% high-strength monofilament PET, this fiber improves tensile stability, reduces reflective cracking, and enhances moisture resistance in hot mix (HMA) and warm mix (WMA) asphalt.
PET fibers disperse uniformly in asphalt, forming a three-dimensional reinforcement matrix. This matrix minimizes early damage, reduces rutting, and enhances long-term pavement resilience under heavy traffic and extreme temperatures.

How Polyester Fibers Enhance Asphalt Pavements
HGM® PET disperses easily throughout asphalt mixtures, creating a reinforcing network that:
-
Reduces reflective cracking
-
Improves tensile strength
-
Controls asphalt drain-down
-
Enhances moisture resistance
-
Mitigates rutting under heavy loads
By improving flexibility and structural integrity, PET fibers extend pavement lifespan and reduce the frequency of rehabilitation.

Looking for Better Macro Synthetic Fiber Performance?
Standard PP macro synthetic fiber is widely used in fiber reinforced concrete, but its performance is often limited by material properties and manufacturing methods.
With lower tensile strength and a relatively smooth surface, conventional macro fibers provide limited anchorage and weak crack-bridging ability after cracking.
In real projects, this often results in insufficient post-crack strength, uneven performance, difficult finishing, and higher dosage just to meet basic requirements.
How Rimix™ 3D Improves Macro Fiber Performance
Rimix™ 3D is a high-performance upgrade to conventional macro fiber, engineered with advanced PP–PE composite materials.
It delivers higher tensile strength and modulus, allowing better load transfer across cracks and more stable post-crack performance.
Its optimized fiber geometry enhances bonding and pull-out resistance, while ensuring excellent dispersion without balling—making mixing and finishing easier on site.
Compared to standard macro fiber, Rimix™ 3D achieves stronger reinforcement with lower dosage, improving both performance and cost efficiency.

Upgrade Fiber Performance — Not Just Dosage
Simply adding more fiber does not always solve performance issues. The key is upgrading the material quality and structural performance of the fiber itself.
Rimix™ 3D provides higher efficiency per kilogram, helping achieve better crack control, improved workability, and more consistent concrete performance across different applications.
