Basalt fiber chopped yarn is a short-cut reinforcement material manufactured from continuous basalt fiber and especially surface-treated to ensure excellent compatibility with asphalt binders. As a basalt fiber additive for asphalt, it provides a high-performance alternative to conventional stabilizing materials such as lignin and polyester fibers. The fiber enhances the mechanical properties of asphalt concrete by improving high-temperature stability, resistance to low-temperature cracking, moisture damage protection, and fatigue performance, helping to extend in pavement service life. Owing to these characteristics, basalt fiber is widely used in road construction for demanding paving projects, including stone mastic asphalt (SMA) and other asphalt reinforcement systems. It contributes to pavement durability and rutting resistance, making it a preferred solution offered by leading basalt fiber suppliers for long-lasting asphalt infrastructure.

Polyester staple fiber is a high-strength, polyester synthetic fiber material produced from modified PET chips through a controlled process of blending, spinning, surface lipophilic treatment, and precision short-cutting. As a proven polyester fiber additive for asphalt, it is engineered specifically for road construction and pavement reinforcement applications, including hot mix asphalt and stone mastic asphalt (SMA) mixtures. When dosed at just 0.4% by weight of the mix, hundreds of millions of short fibers are uniformly distributed throughout each cubic meter of asphalt concrete, forming a three-dimensional reinforcement network that significantly improves tensile, shear, compressive, and impact strength. The result is asphalt pavement with measurably enhanced high-temperature stability, low-temperature crack resistance, fatigue resistance, water stability, and anti-skid performance — making it the preferred choice for road rehabilitation and long-life pavement design.
