Product Introduction
Basalt chopped yarn is made from continuous basalt fiber through special surface treatment and fixed-length cutting. As a competitive alternative to polyester fiber, lignin fiber in asphalt concrete, it significantly improves high-temperature stability, low-temperature crack resistance, water damage resistance and fatigue resistance, greatly extending the service life of asphalt concrete.
