Adding fiber in asphalt mixture not only improved their performance, and its structure parameters were changed. Based on the two kinds of road-fibers, by means of indoor experiments, the paper analyzed the relationship with different types, different dosage of fiber of asphalt mixture of physical and mechanical parameters, and the influent law of performance, revealed the mechanical parameters characteristics and performance of fiber asphalt mixture, it puts forward measures and methods improving fiber asphalt mixture in the design and construction and engineering quality, and provides reference of the popularization and application of the asphalt pavement.
