Recycled plastic fiber reinforced hot-mix asphalt

Various reinforcing methods are widely utilized to extend the performing life of Hot-Mix Asphalt especially in view of fatigue cracks or rut resistance such as polymer modification of asphalt binder or stone mastic asphalt mixtures. Although some strengthening effects of such solutions have been reported, those may not guarantee long-term toughness or fatigue resistance because modified asphalt mixtures sometimes result in too stiff binder to sustain hysteresis external loading in bending-beam or cyclic direct tensile tests set-up. In addition, high costs and difficulties in field work with them are usually pointed out as drawbacks to apply to fields frequently. A new recycled plastic fiber-reinforced Hot-Mix Asphalt is proposed to provide more effective reinforcements in structural enhancement and usefulness in terms of costs. A small amount of recycled plastic fibers in Hot-Mix Asphalt leads to significant increases in phenomenological toughness and fatigue life of mixtures compared to un-reinforced Hot-Mix Asphalt mixtures as resulting from indirect tensile tests and four-point bending beam tests.
