Polyacrylonitrile Fiber is a new kind of synthetic reinforcement fiber made of Polyacrylonitrile resins by special technique. It can
strengthen the anticrack of the asphalt and cement concrete. Its function in the cement concrete is similar to the Polypropylene Fiber and in the
asphalt concrete is similar to the Polyester Fiber.The Physicochemical Properties of Polyacrylonitrile FiberRegular Spec:
Material Form | Polyacrylonitrile | The Type of the Fiber | Bunchy monofilament |
Identical Diameter(μm) | 15±2 | Density(g/cm3) | 1.18~1.2 |
Length(mm) | 6--12 | Modulus of Elasticity(MPa) | ≥3500 |
Elongation at Break(%) | ≥10 | Tensile Strength | ≥500 |
The Mechanism of Action of Polyacrylonitrile Fiber in the MASTIC1) The function of absorptionThe diameter of the fiber is general 15µm, and the specific surface is very large- the surface area per gram could reach to several square meters.The fibers distribute in the asphaltum, and the 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 stabilityThe 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 reinforcementThe 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.
