TB pan fiber is mainly used for concrete reinforcement and could be used for asphalt conctere,too.
TB-PAN-Fiber
TB-PAN-Fiber is a new kind of synthetic reinforcement fiber made of PAN resins by special technique. It can strengthen the anti-crack of the asphalt and cement concrete
Its function in the cement concrete is similar to the TB-PP-Fiber and in the asphalt concrete is similar to the TB-PES-Fiber.

The Mechanism of Action of TB-PAN-Fiber in the MASTIC
1. The function of absorption
The diameter of the fiber is general 15µm, and the specific surface is very large — the surface area/g could reach to several square meters
The fibers distribute in the asphaltum, and their huge surface area becomes the soakage interface
In the interface layer, the physical and chemical actions between the asphaltum and fibers make the asphaltum distribute on the surface in unimolecule, further form the firm asphaltum interface layer
At the same time, because both the fibers and the surrounding asphaltum attached the surface of the aggregate, the asphalt membrane is enlarged, makes for slowing down the ageing rate, further prolong the lifetime of the roads
2. The function of stability
The asphaltum attached by the crossbinding fibers increased the proportion of the structural asphaltum, decreased the free asphaltum, enforced the treacliness of the MASTIC, improved the softening point, thereby improved the stability of the SMA bulking material
3. The function of reinforcement
The fibers distribute in the MASTIC in 3D and stochastic, which could prevent the crack of the bulking material, consequently increase the healing power of nature of the crack of the asphalt roads and decrease the crack.
