6mm length basalt fiber for asphalt concrete high heat resistance fibre

Basalt fibers are continuous fibers made by high-speed drawing of platinum-rhodium alloy wire-drawing leaks. Similar to glass fibers, its properties are between high-strength S glass fibers and alkali-free E glass fibers. Pure natural basalt fibers are generally brown in color, and some are golden in color. Basalt fiber is a new kind of inorganic environmental friendly green high performance fiber material. It has been widely used in fiber reinforced composites, friction materials, shipbuilding materials, thermal insulation materials, automotive industry, high temperature filter fabrics and protection fields.

  The role of basalt fibers in various asphalt mixtures such as SMA, OGFC, AC, AK, etc.

1. Increasing Viscosity and Modulus of Asphalt

2. Improving the Rutting Resistance at High Temperature

3. Improving Low Temperature Crack Resistance

4. Improving the Water Damage Resistance of Asphalt Pavement

5. Improving the Antioxidant Aging and Fatigue Durability of Asphalt Mixture
