As one of the main materials for modern road construction, the optimization of the performance of hot asphalt concrete special fiber is crucial to improving road quality. Among them, the addition of special fibers has shown a series of unique advantages in improving the skid resistance of pavement.Special fibers significantly improve the skid resistance of pavement by increasing the roughness and adhesion of hot asphalt concrete. These fibers are three-dimensionally dispersed in the asphalt mixture, overlapping each other to form a network structure, which effectively enhances the mechanical properties and stability of asphalt concrete. When a vehicle travels on a road surface containing special fibers, the friction between the tire and the road surface increases, thereby reducing the risk of vehicle skidding and improving driving safety.Special fibers can also effectively slow down the aging of the road surface and extend the service life of the road surface. Over time, traditional asphalt concrete pavements are prone to wear and smoothing, resulting in a decrease in skid resistance. The addition of special fibers can slow down this process, allowing the road surface to maintain its roughness for a longer time, thereby continuously providing good skid resistance.In addition, special fibers can also improve the drainage performance of hot asphalt concrete. In wet or rainy conditions, water on the road surface can easily reduce the friction between the tire and the road surface, increasing the risk of vehicle skidding. The addition of special fibers can improve the pore structure of asphalt concrete, improve drainage efficiency, and reduce the adverse effects of water accumulation on the anti-skid performance of the road surface.It is worth mentioning that the type and dosage of special fibers have an important influence on the improvement of the anti-skid performance of the road surface. By scientifically and rationally selecting the fiber type and dosage, the anti-skid performance of hot asphalt concrete can be further optimized to meet different road grades and traffic needs.In summary, hot asphalt concrete special fiber has significant advantages in improving the anti-skid performance of the road surface. These advantages not only improve the safety of the road, but also extend the service life of the road surface, providing strong support for modern road construction.
