Cellulose fiber for asphalt SMA is called GSMA.It is a high quality and high purity granular fiber made by physical extrusion of pure flocculated fiber.It is widely used in SAM pavement, which can improve the anti-aging ability and durability of asphalt layer, thus greatly extending the service life of pavement.
Cellulose fiber for asphalt SMA can form a three-dimensional network in asphalt, which plays the role of reinforcing, and at the same time obstructs the flow of asphalt, making the asphalt membrane in a relatively stable state. Even when the temperature expansion, it can guarantee the asphalt does not flood oil.Moreover, the fiber adsorption is strong, which can fully absorb the bitumen inside the mixture and tightly adsorb the bitumen on the surface. As a result, the amount of bitumen is increased, the bitumen film becomes thicker, thus improving the anti-aging ability of the bitumen layer and greatly extending its service life.At the same time, the particle fibers also have the characteristics of easy dispersion. The pre-mixing in 5-15 seconds can guarantee its uniform distribution, and this characteristic can also avoid the generation of micelle in the mixture.
