Polyacrylonitrile fiber ,also know as PAN fiber or Acrylic fiber for Concrete has higher tensile strength, higher initial modulus and stable chemical properties than other fibers. Therefore, the fiber has acid and alkali corrosion resistance, light resistance, weather resistance, and good dispersion, oil absorption. In practical application, the bonding force with concrete matrix is strong, which improves the cohesion and fatigue resistance of concrete, and enhances the impermeability, frost resistance and impact resistance of concrete. Therefore, it is widely used in the engineering of asphalt concrete and cement concrete.

Feature&benefits
1. Adsorbing asphalt by tackifying effect, increasing asphalt content in mixture under the condition of keeping the same viscosity of asphalt mortar. Adsorption of light oil in asphalt makes residual non adsorbed asphalt viscosity increase. The high temperature stability of asphalt mixtures is improved with the increase of the viscosity (flow deformation resistance) of asphalt mineral powder fiber mixtures.
2. Toughening enhances the bonding force between asphalt, cement binder and aggregate surface, prevents peeling and improves the water damage resistance. Improve the deformation capacity and toughness of asphalt mortar and cement mortar at low temperature, and reduce cracking at low temperature. Fiber plays an orientation role in the deformation process of asphalt mortar, which greatly improves the deformation following ability of asphalt mixture.
3. The asphalt and cement mixtures with fiber reinforcement have good fatigue resistance, and their fatigue life increases significantly. The asphalt and cement mixtures with fibers have good impact toughness, which is especially suitable for the asphalt overlay on the old cement concrete pavement. The wear resistance of asphalt and cement mixtures mixed with fibers is improved, which can be used in special places such as anti-skid pavement and tracked vehicle pavement.
4. The volume of asphalt adsorbed by most fibers expands slightly after filling, which can effectively reduce the voids in asphalt pavement, reduce the size of voids and improve the uniformity of void distribution. The use of water-increasing fibers can improve the bleeding capacity of asphalt mixture, shorten the residual time of moisture in asphalt pavement, and reduce the phenomenon of water damage.
5. Because it has more characteristics than other fibers, its toughness, impact resistance and crack resistance are further improved in cement concrete and cement products.
