High-Performance Fiber Solutions for Fiber-Reinforced Asphalt Concrete
What Are Basalt Fibers for Fiber-Reinforced Asphalt Pavements?
PIONEER® HGM® Basalt is a high-performance chopped basalt fiber engineered specifically for asphalt pavements and overlays. Produced from 100% natural basalt rock, these fibers significantly enhance the structural integrity of fiber-reinforced asphalt concrete (FRAC).
By forming a three-dimensional reinforcement network inside hot mix or warm mix asphalt, HGM® Basalt improves resistance to cracking, rutting, fatigue, and deformation under heavy traffic loads and thermal stress. As a mineral fiber with excellent heat, chemical, and UV stability, it provides long-term durability in demanding pavement environments.

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.
