High Value at Low Cost

HGM® PET delivers reliable reinforcement at a significantly lower cost compared to premium aramid or PAN fibers. This cost-efficiency makes it ideal for projects with tight budgets, such as secondary roads and community infrastructure. It helps extend pavement lifespan and improve crack resistance, ensuring long-term value without exceeding financial constraints.

Thermal and UV Stability for Urban Roads

HGM® PET remains structurally stable at temperatures between 130°C and 180°C, making it suitable for hot mix and warm mix asphalt. Its formulation provides enhanced resistance to UV exposure, helping prevent premature surface degradation. This feature is particularly useful for city roads and parking lots exposed to direct sunlight year-round.

Enhancing Asphalt Flexibility and Crack Resistance

The fiber structure of HGM® PET helps dissipate thermal and mechanical stress, minimizing the risk of surface cracking due to temperature variation or heavy usage. Its even distribution within the mix boosts the overall elasticity of the pavement, making it especially effective in climates with large seasonal shifts.

Compatible with Standard Mixing Processes

HGM® PET can be directly added into asphalt plants without modifying existing equipment. It is available in meltable bags, paper bags, or bulk formats to ensure safe, dust-free, and efficient dosing during mixing. This versatility allows contractors to adopt fiber-reinforced asphalt without operational interruptions.

Trusted in Residential and Commercial Projects

HGM® PET has been successfully used in residential developments, parking areas, business parks, and secondary urban roads. Its proven performance has led to its adoption in multiple municipal guidelines as a recommended cost-effective reinforcement material for asphalt mixtures.

Conclusion

HGM® PET combines functionality and affordability, making it a smart choice for reinforcing asphalt pavements in cost-conscious projects. As cities and towns strive to improve road durability without inflating budgets, this fiber offers the perfect balance of price and performance.
