In order to study the effect of fiber on the properties of asphalt mortar,the properties of lignin fiber,polyester fiber and basalt fiber were summarized and analyzed,and the high and low temperature properties of fiber asphalt mortar were studied and analyzed by using three indexes,rutting factor and tensile fracture energy.The results showed that the performance of the three fibers could be improved to varying degrees,and the lignin fiber had the best improvement effect.Combines the fiber's own heat Stability and economy,according to the actual engineering situation to choose the appropriate fiber type.
