Lignin fiber is an organic fiber produced by physical and chemical treatment of natural wood. Since the temperature of the wood during chemical treatment is as high as 260 degrees Celsius or more, the treated cellulose is chemically stable under normal environmental conditions and is not corroded by acids, alkalis and general solvents, and thus is widely used for SMA (asphalt). Hoofed gravel mixture) and OGFC open graded on the highway pavement with anti-sliding structure. The company can provide flocculent and granular wood fiber, the product is green and environmentally friendly, does not affect the environment, and is harmless to the human body.
Product Features:
Reinforcement: The fiber is blended in the SMA mixture. The fiber exists in the mixture in a three-dimensional dispersed phase. Like various steel fiber concrete, geogrid, geotextile and other reinforced materials, it can be added.
Stabilization: The fiber makes the asphalt film in a relatively stable state, especially in the summer high temperature season. When the asphalt is heated and expanded, the internal voids of the fiber will become a buffering space, which will not become free asphalt and oil, and also have high temperature stability.
Product Features:
Dispersion: If there is no fiber, the used bituminous ore fine powder is likely to become a micelle, which cannot be evenly dispersed between the aggregates. The pavement will clearly see the presence of "oil spots" on the pavement, and the fibers can make the glue.
Tackifying: Improves adhesion. The fiber will increase the adhesion of the asphalt to the mineral material, and the adhesion between the aggregates is improved by the bonding of the oil film.
Instructions:
Instructions:
When the asphalt mixture is dry-mixed, the addition amount is 0.3% by weight of the asphalt mixture.
Application range:
● Anti-sliding surface of highways and urban expressways and trunk roads ● Alpine areas, prevention of temperature shrinkage cracks ● Airport runway, overpass, ramp ● Road sections with heavy traffic sections, heavy loads and overloaded vehicles ● High temperature and rainy area pavement, parking lot ● Deck paving, especially steel deck pavement ● Bus lanes for city roads ● Intersections of city roads, bus stops, parking lots, freight yards, port terminals
