Hybrid Aramid fiber is one type asphalt fibers ,made by blending aramid with polymer fibers ,designed for asphalt pavement reinforcement .

The main advantages of asphalt fibers include improving the crack resistance of the mixture, enhancing bonding strength, and improving the stability of the mixture. Specifically, the addition of fibers can form a network structure inside the asphalt mixture, which helps to disperse stress and reduce crack propagation caused by temperature changes or traffic loads. Fibers can also adsorb a certain amount of asphalt, prevent oil loss, enhance material adhesion, and thus improve the overall stability of the road surface.
