How Fluffy Lignin Fibers Enhance Asphalt Pavements
HGM® F-Lignin fibers disperse uniformly inside asphalt mixes, forming a retentive fiber network that:
-
Absorbs excess asphalt binder
-
Prevents drain-down and bleeding
-
Improves moisture resistance
-
Enhances rutting resistance
-
Stabilizes open-graded and porous asphalt
Ideal for wet climates, high-traffic pavements, and SMA/OGFC mixtures.

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.

FAQ
HGM® F-Lignin is a fluffy lignin-fiber product for asphalt binder stabilization and drain-down control. It is designed for incorporation into compatible asphalt mixtures such as SMA, OGFC and porous asphalt.
Its primary role is to help stabilize asphalt binder and control drain-down during mixture production and placement. Actual performance depends on fiber dosage, binder content, aggregate structure and mix design.
Use the current HGM® F-Lignin Technical Data Sheet to select the initial addition rate, then confirm the final dosage through the applicable asphalt mix-design and performance-validation process.
Yes, HGM® F-Lignin can be evaluated in Stone Mastic Asphalt where binder stabilization and drain-down control are required. Final dosage should be verified for the selected SMA design.
HGM® F-Lignin can be evaluated in compatible OGFC mixtures where binder retention and drain-down control are important processing requirements.
