Basalt fiber chopped strand for asphalt concrete

【product description】
Basalt fiber chopped strand is based on the continuous basalt fiber though special surface treatment, which is cut in a certain length according to user demand. Basalt fiber is competitive replacement of polyester fiber, wood fiber, etc. Which can significantly improve the high temperature stability, thermal crack, water damage resistance and fatigue resistance, etc. Can greatly extend the service life of asphalt concrete.
Basalt chopped fiber is coated with a special surface treatment agent to make them binding strongly with asphalt concrete.Basalt chopped fiber can significantly improve asphalt concrete the high temperature stability, low temperature crack resistance , water damage performance and fatigue resistance.

【Forming Process:】
Basalt fiber chopped strand is cut by the basalt fiber with special surface treatment.
【Product Features】
1. Can raise the utilization rate of bitumen, can reduce the flushing.
2. Can improve the dynamic stability, enhance 30% resistance to rutting of a asphalt pavement under a high temperature.
3. Can reduce the thermal cracking and improve 40% resistance to the low-temperature cracking.
4. Can improve the water damage resistance.
5. Enhance the fatigue resistance by more than 20% and prolong the pavement service life.
6. Improve the efficiency of asphalt and oil flooding. Improve the dynamic stability,
【Product Application】
Basalt fiber chopped strand is suitable for dense grade asphalt concrete (DGAC), stone mastic asphalt (SMA), open-grade asphalt (OGFC). Various asphalt concrete pavements such as fiber seals.
