Dynamic properties and fatigue life of stone mastic asphalt mixtures reinforced with waste tyre rubber

Today, virgin polymer modified asphalt mixes are comparatively more expensive for road pavement. One way to reduce the expense of such construction and to make it more convenient is the application of inexpensive polymer, such as waste polymer. The primary aim of this study was to investigate the ef...
