Experimental evaluation and recyclability potential of asphalt concrete mixtures with polyacrylonitrile fibers

Recently, the use of fibers has become an attractive option to be implemented as reinforcement in Asphalt Concrete (AC) mixtures. Nonetheless, few studies have been carried out evaluate recyclability potential AC mixtures incorporating fibers. In this study, reinforcing effect polyacrylonitrile (PAN) is investigated. Air voids, Marshall stability, indirect tensile strength (ITS), moisture sensitivity, compactability, rutting, stiffness, and fatigue were tests taken into consideration. addition, bituminous manufactured with higher quantities artificial reclaimed asphalt pavement containing PAN (PANRAP) evaluated experimentally. The results indicate that significantly increased resistance permanent deformation mixture. Improvements ITS, sensitivity stiffness keeping same life also observed. a suitable performance was found PANRAP relation control mix remarkable increases noted. present investigation provides technical evidence recycling up 50% without presence rejuvenators.
