Road Construction Chemicals
Product Position:
Lignin road fiber is a high-quality pelletized lignin cellulose stabilizer specifically designed for SMA (Stone Mastic Asphalt) pavements. Manufactured from natural wood through high-temperature/pressure thermochemical treatment, it serves as an asphalt absorbent, reinforcement stabilizer and toughening agent in SMA mixtures, effectively preventing binder draindown while enhancing rutting and cracking resistance.
