Polyacrylonitrile Fiber for Asphalt Concrete(PAN-Fiber) - TB-PAN-6S,TB-PAN-12S

TB-Polyacrylonitrile-Fiber is a new kind of synthetic reinforcement fiber made of Polyacrylonitrile 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.

Specification

Regular Spec: TB-PAN-6S; TB-PAN-12S

Function

1. 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. 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. 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.
