Abstract
This paper selects three different fibers: short-cut mineral fiber, mineral cotton fiber and lignin fiber, through the laboratory test to analysis the homogeneity and way-use performance of fiber SMA. Contrast test results show that the homogeneity of adding mineral cotton fiber and lignin fiber of SMA mixture is nearly at the same degree, which are all better than adding short-cut mineral fiber. Adding short-cut mineral fiber with SMA has poor water stability, but the high temperature stability is the best; At the same time, the homogeneity of the fiber asphalt mixture in this paper has a certain effect with the road performance, but impacts little with the absolute value of it.
