ASPHALT POWER Cellulose Fiber for Asphalt Pavement
ASPHALT POWER cellulose fiber is natural and organic fiber. It appears gray flocculent. The flocculent cellulose fiber can be made from a special process, and when mixed with asphalt, forms a granular mixture, of which 90 percents are natural wood fibers and 10 percents is asphalt mixture. It has a coarse irregular surface high endurance. This will guarantee that the high proportion of asphalt will not affect the asphalt mixture, and prevents the asphalt binder from bleeding away from mineral materials.
High quality
1.High durability--Due to the mutual friction among the course aggregates of the inner stone skeleton, SMA has excellent anti-rutting performance in high temperature. It can provide good driving qualities and safety.
2.Skid resistance and noise reduction--Due to the higher texture depth, SMA pavement can provide excellent interface between pavement and tyre, as well as an efficient noise reduction in the traffic noise.
3.Durability--It is proved that SMA pavement can resist permanent deformation, rutting, abrasion, temperature crack, traffic crack, and un-consolidation. According to the cases of different countries in different weather condition, the service life of SMA pavement can reach 20 years or even longer.
Application
The chemical property of ASPHALT POWER cellulose fibre is very steady. It will not be corroded by acid, alkali and common solvent, and can be widely applied in highway pavement of SMA (stone matrix asphalt) and OGFC.
1. Antiskid surface of highway, urban expressway and arterial highway
2. Maintenance and repair of old pavement
3. Bridge deck pavement
4. Urban bus accommodation lane
5. Airport runway
Technical Data
ASPHALT POWER cellulose fiber meets the quality requirements of cellulose fiber described in Cellulose Fiber for Asphalt Pavement JT/T533-2004, which is edited by Ministry of Communications of the Peoples Republic of China.

Using Methods
ASPHALT POWER cellulose fiber can be put into the mixing plants directly without opening the package. Generally, the fiber can be mixed in different kinds of mixer for 3-5 seconds. Basically, the dosage of lignin fiber for SMA pavement is 0.3%-0.5%. The highest mix temperature can reach 200 °C,and the pavement temperature can reach 180°C.
Notice
The moistened, agglomerate and inhomogeneously dispersed fiber should not be used during construction.
