Modified thread throwing type ceramic fiber asphalt mixture as well as preparation method and application thereof

The invention discloses a modified thread throwing type ceramic fiber asphalt mixture as well as a preparation method and application thereof, and belongs to the technical field of asphalt modification. The modified thread throwing type ceramic fiber asphalt is prepared by the following method: under the condition of high temperature, aggregate and modified thread throwing type ceramic fibers are mixed and stirred; then adding the matrix asphalt, and stirring; and finally, adding the modified mineral powder, and stirring to obtain the modified thread throwing type ceramic fiber asphalt mixture. Based on the combined action of the modified thread throwing type ceramic fiber and the modified mineral powder, the characteristics of the asphalt material are changed in the microstructure, so that the performance of the asphalt mixture is greatly optimized, and the high-temperature stability, the low-temperature stability and the water stability are remarkably improved. 本发明公开了一种改性甩丝型陶瓷纤维沥青混合料、其制备方法及应用，属于沥青改性技术领域。本发明
