Abstract
Adding fiber to asphalt can effectively improve asphalt performance,improve asphalt pavement life.Corn stover fiber,road lignin fiber and construction lignin fiber were made of different kinds of fiber modified asphalt,its softening point,penetration,ductility of a series of experimental studies,compared with different kinds of different dosage of fiber on the asphalt modification effect.At the same time using polarized light microscope and scanning electron microscope on the fiber and its modified asphalt into the field of microscopic observation,the fiber and asphalt between the role of the mechanism of analysis.The study proved that lignin fibers and corn stover fibers are in a certaindegree to enhance the performance of asphalt,corn stover fibers to enhance the effect of the best,and the optimal fiber dosage of 3%,the strength of the fiber structure of the fiber structure of the asphalt high-temperature properties of the modification of the effect of the asphalt,the asphalt low-temperature effect of the weak.关键词
