Polyester Fiber for Asphalt Pavements
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.

Applicable Standards for Fiber-Reinforced Asphalt Concrete
Performance of HGM® PET should be evaluated through project-specific asphalt mixture design and testing. Applicable test methods depend on agency and project specification requirements.
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.

FAQ
HGM® PET is a modified monofilament polyester fiber designed for direct incorporation into asphalt mixtures and pavement reinforcement applications.
No. HGM® PET is designed for asphalt applications. PIONEER® HPM® PET is a separate polyester-fiber product for concrete, with different dosage, application and technical requirements.
Final dosage should follow the current HGM® PET Technical Data Sheet and be selected according to asphalt mix design, fiber length and required performance.
HGM® PET can be evaluated in compatible hot-mix asphalt systems. Confirm dosage, addition sequence, mixing conditions and product distribution for the selected mixture.
HGM® PET may be evaluated in compatible warm-mix asphalt systems. Suitability depends on the WMA technology, binder system, plant temperature and project requirements.
