Every summer, hot flying, you must not know, we usually go to the road is also afraid of hot summer!
The problem came, in the face of hot, what material casting on the road to ensure its safety? Today, the slightest edge of small series for everyone to introduce a fiber - lignin fiber
Road lignin fiber is one of the important raw materials for the production of hot mix of asphalt horseshoe gravel mixture (SMA), which is the organic fiber obtained by chemical treatment of natural wood, the appearance of cotton-like, white or gray. In the SMA pavement plays an irreplaceable role!
Here, we take a look at the road with lignin fiber in the SMA pavement in the specific role played:
(1) reinforcement effect
The fibers are blended in the SMA mix, and the fibers are present in the mixture in a three-dimensional dispersed phase, like stiffeners such as steel fiber concrete, geogrids, geotextiles, and the like.
(2) decentralized effect
If there is no fiber, the amount of asphalt powder is likely to become a micelle, can not be evenly dispersed between the aggregate, paved on the road will clearly see the "oil spots" exist, the fiber can make the mic dispersion.
(3) the role of adsorption and absorption of asphalt
The addition of fibers to the SMA mixture is due to the sufficient adsorption (surface) and absorption (internal) asphalt, which increases the amount of bitumen and thickens the asphalt film to improve the durability of the mixture.
(4) Stable effect
Fiber so that the asphalt film in a relatively stable state, especially in the summer hot season, asphalt heated expansion, the fiber internal voids will become a buffer room, not to become free asphalt and oil, high temperature stability is also good.
(5) thickening effect
Fiber will increase the adhesion of asphalt and mineral material, through the oil film bonding, improve the adhesion between the aggregate.
Road lignin fiber with its excellent quality, to ensure that in the production, transportation, paving and rolling process mixed material uniformity and stability. The asphalt pavement high and low durability and durability, played a considerable role. For the construction of high-quality asphalt pavement laid the cornerstone. Has been widely used in the construction and construction of SMA asphalt pavement, fiber reinforced asphalt pavement, cement pavement cover, permeable asphalt mixture.
Characteristics of lignocellulose
1. Anti-skid wear, anti-fatigue, anti-high temperature rut.
2. continuous paving, the road height is high, good seams.
3. Applicable to all kinds of forced mixing machine.
4. Has a good drainage.
5. Reduce noise and meet environmental requirements.
6. Price is lower than similar products.
Our "Silk Road" road lignin fiber has been used in some provinces and cities highway and international airport. To learn more about Silk Road fiber products, please call us!
