Road lignin fiber is the production of hot mix asphalt mastic mixture (SMA) is one of the important raw materials, it is natural wood chemical treatment of organic fibers, the appearance of cotton-like, white or gray. In the SMA pavement plays an irreplaceable role!

Here, we look at road lignin fibers in the SMA pavement in the specific role played:

(1) reinforcement effect
In the SMA mixture of fibers, fibers in the mixture in a three-dimensional dispersed phase exists, like a variety of steel fiber reinforced concrete, geogrid, geotextile and other reinforced materials, can play a reinforcing role.

(2) dispersion
If there is no fiber, a large amount of asphalt powder is likely to become micelles, can not be evenly dispersed in the aggregate between the pavement on the road will clearly see the "oil spot" exists, the fiber can make the micelle dispersed.

(3) the role of adsorption and absorption of asphalt
The addition of fibers to the SMA mixes the effect of sufficient adsorption (surface) and absorption (internal) of the asphalt, increasing the amount of asphalt, thickening the asphalt film and increasing the durability of the mix.

(4) stabilizing effect
Fiber make the asphalt membrane in a relatively stable state, especially in the summer heat season, the asphalt thermal expansion, the fiber internal space will also become a buffer of space, will not become free asphalt and oil, high temperature stability is also good.

(5) thickening effect
Fiber will increase the adhesion of asphalt and mineral materials, through the oil film adhesion, improve the bond between the aggregate.

Road lignin fiber with its excellent quality, to ensure that in the production, transportation, paving and rolling process of the homogeneous mixture and stability. On the high and low asphalt pavement and improve the durability, played a significant role. For the construction of high-quality asphalt pavement laid the cornerstone. Has been widely used in the new and construction of SMA asphalt pavement, fiber reinforced asphalt pavement, cement pavement cover, permeable asphalt mixture.

Jiangsu Silk Edge Fiber Co., Ltd. production of "new ideas" road lignin fiber with the new features:

1. Anti-skid wear, anti-fatigue, high temperature rut.
2. Continuous paving, the road smoothness, good joints.
3. Applicable to all kinds of forced mixers.
4. Has a good drainage.
5. Reduce noise, meet environmental requirements.
6. Prices lower than similar products.

Our "new ideas" road with lignin fibers have been in some provinces and cities in the highway and the international airport to be applied. To learn more about the "new ideas" for lignin fiber product details, please call us!
