HGM® PAN
Polyacrylonitrile Asphalt Fibers
Synthetic fiber for asphalt pavement
Since 2002, we have specialized in concrete crack resistance, waterproofing, and anti-corrosion technologies.
Product Description
PIONEER® HGM® PAN is made from 100% pure Polyacrylonitrile and is specifically designed as a monofilament fiber for asphalt reinforcement. Adding PIONEER® HGM® PAN to asphalt mixes improves adhesion, high-temperature stability, and fatigue durability. It also enhances low-temperature crack resistance and prevents reflective cracking, making it an effective solution for addressing asphalt pavement durability issues and early damage, and for extending the lifespan of asphalt surfaces.
PIONEER® is a leading brand in the engineering fiber industry with a 22-year history. Its fiber-reinforced concrete technology has been awarded the China National Science and Technology Progress Award. The PIONEER® product line includes four main series: HPM® Micro Fibers, HTM® Macro Fibers, HGM® Asphalt Fibers, and PNE® Steel Fibers. These products have been successfully applied in thousands of major projects worldwide and are highly regarded in the civil engineering field.
Uses
PIONEER® HGM® PAN is typically used in the intermediate and surface layers of asphalt pavements to enhance overall performance, extend pavement lifespan, and reduce long-term maintenance costs. Applications of PIONEER® HGM® PAN include:
-
New asphalt pavement surfaces
-
Overlays on old asphalt pavements, existing concrete pavements, or bridge decks
-
Maintenance and repair of asphalt pavements
-
Surfacing for steel bridge decks
-
Large-scale asphalt pavements, such as those for airports and parking lots
-
Asphalt concrete surfaces with various gradations (e.g., SMA, AC, LH)
-
Asphalt concrete surfaces under diverse conditions, including hot mix asphalt, warm mix asphalt, and patching
