Fibers enhance the asphalt’s ability to withstand deformation under traffic loads, preventing common distresses such as rutting and potholing.
Fiber-reinforced asphalt concrete (FRAC) is a modern class of asphalt that incorporates synthetic fibers into its composition. These fibers are distributed uniformly within the asphalt, creating a three-dimensional reinforcement matrix that fundamentally enhances the asphalt’s tensile strength, resilient modulus, and overall durability.
FRAC combats the prevalent cracking, rutting, and raveling issues in conventional asphalt, providing a resilient infrastructure solution adaptable to various climatic conditions and traffic patterns.
Integrating fibers into asphalt mixtures provides numerous benefits, such as:
Fibers enhance the asphalt’s ability to withstand deformation under traffic loads, preventing common distresses such as rutting and potholing.
The fibrous network within the asphalt effectively controls crack propagation, which is crucial for maintaining structural integrity and prolonging surface life.
Fiber-reinforced pavements exhibit higher load-bearing capacity, making them suitable for areas with heavy vehicular traffic.
The durable nature of fiber-reinforced asphalt reduces the need for frequent repairs and overlays, decreasing long-term maintenance costs.
By extending pavements’ life cycles, the technology contributes to sustainability by minimizing the frequency of asphalt replacement and associated environmental impacts.
FORTA’s fiber-reinforced asphalt is engineered to perform across a wide range of new construction and pavement rehabilitation applications. Whether the project involves a high-speed highway overlay or a neighborhood street resurfacing, adding Forta fiber to the asphalt mix delivers the same three-dimensional reinforcement benefit at the standard dosage of one pound per ton.
Aviation pavements endure extreme concentrated loads, repeated thermal cycling, and strict maintenance windows. FORTA’s asphalt fiber has a high-tensile aramid fiber network and provides the structural resilience needed for heavy aircraft operations while reducing the risk of reflective and thermal cracking — minimizing costly closures and resurfacing cycles.
Reflective cracking is one of the most persistent and costly challenges in overlay projects. FORTA’s fiber matrix actively bridges existing crack patterns in the underlying layer, delaying reflective cracking breakthrough and extending overlay service life significantly compared to unmodified mixes.
High tire pressure, frequent turning movements, and sustained static loading from trucks and heavy equipment accelerate rutting and surface cracking in parking areas. Fiber reinforcement addresses all three primary failure modes, reducing long-term repair costs and extending time between resurfacing cycles.
Lower-traffic applications still benefit substantially from FORTA’s crack resistance and durability enhancements, particularly in regions with pronounced freeze-thaw cycles or significant seasonal temperature swings. Fiber-reinforced residential pavements require fewer crack-fill and patching interventions over their service life.
For asphalt racing circuits and drag strips, surface consistency and structural integrity directly affect both safety and performance. FORTA asphalt fiber provides a reinforced pavement substrate capable of handling high-speed dynamic loading and repeated thermal stress from braking zones, delivering a more stable surface throughout the racing season.
City streets and arterials repaved with FORTA fiber-reinforced asphalt routinely outperform conventional paving in long-term pavement condition index (PCI) assessments, reducing the frequency of disruptive maintenance cycles and stretching municipal pavement budgets further.

Fibers work by bridging microcracks, increasing toughness, and improving the mix’s ability to absorb energy without fracturing. Even at small dosages, millions of fibers dispersed throughout the mixture enhance crack resistance and structural integrity.
No. Fiber reinforced asphalt can be produced without any modifications to the asphalt plant, making it simple to incorporate into existing operations. FORTA fibers have been used in thousands of asphalt plants worldwide across several decades.
Yes. FORTA fibers can be used in dense graded, SMA, OGFC, and recycled mixes, though dosage may vary depending on the application and need.
No. Fiber reinforced asphalt is placed and compacted the same way as conventional asphalt, with no special equipment or procedures needed.
Fibers are typically added before the liquid asphalt binder, either by bag or fiber feeder through the RAP port for continuous drum plants or hot bin doors in a batch plant. Proper and uniform dispersion should be verified.
