Research on the Road Performance of Basalt Fiber Modified Asphalt and Asphalt Mixture
This study aims to investigate the improvement effect of basalt fiber on the performance of as-phalt and asphalt mixture.The treatment effects of different surface modifiers were compared,and the differ-ences in softening point,cone penetration,and force ductility of asphalt mastic were analyzed.The influence of basalt fiber on the high-temperature stability,low-temperature cracking resistance,and water stability of asphalt mixture was also analyzed.The results show that the modified fiber enhanced the physical adsorption a-bility between the fiber and the asphalt,improved the shear strength and low-temperature tensile performance of the modified asphalt,significantly improved the high-temperature stability and low-temperature cracking resistance of the asphalt mixture,and had no significant effect on the water stability.
