Experimental Investigation on Performance of Fiber Asphalt Mixture
The paper investigates positive effects of three kinds of fibers on the performance of asphalt concrete mixture, which include mineral fiber (Fiberand®), lignin fiber and polyacrylonitrile (Dolanit@AS). The contrast experiments of AC-13 SBS modified asphalt mixture added fibers were carried out. The results reveal that the pavement performance can be improved remarkably if appropriate fibers are added into the asphalt mixture. The method of determining optimum mixture ratio was proposed on the basis of road performance of asphalt concrete. It is more reasonable to adopt comprehensive indicator containing stability and dynamic stability in determination of the optimum mixture ratio of asphalt concrete.
