Granular wood fiber is a kind of granular plant fiber made from wood and recycled waste paper with wood fiber as the main component, and added with granulating agent (such as asphalt and other non paraffin bonding materials, the softening point of paraffin is lower than that of asphalt, which will affect the softening point of asphalt and affect the road performance) through chemical or mechanical processing. The main mechanism is that the fiber makes asphalt firmly form a layer of asphalt film on the surface of aggregate; And because of the role of fiber, the asphalt film of this layer becomes thicker, thus increasing the amount of asphalt, thus greatly improving the aging resistance of the asphalt layer and greatly extending its service life. Granular fiber is applicable to SMA asphalt pavement, fiber reinforced asphalt pavement, open graded or permeable asphalt pavement, and cement pavement covered with permeable asphalt mixture.
