Comparing Tests on Water Relating Stability of Polyester and Polyacrylonitrile Fiber Reinforced Asphalt Mixture
Four kinds of fiber reinforced asphalt mixture formula are made, i.e., non fiber, polyester fiber, polyacrylonitrile fiber and the compound of the last two fibers, and then the Residual Marshall Stability (RMS) tests and Residual Cleavage Strength (RCS) tests are carried out. It is found that with the adding of fiber, the RMS is raised from 88% to 92% and the RCS from 86% to 88%. In the view of water-relating stability enhancement, the compound fiber is the best, the polyacrylonitrile fiber is the second, and the polyester fiber is at last, however, it is still better than plain asphalt mixture. More compaction work should be done on fiber reinforced asphalt mixture in practical engineering.
