Abstract <p>A research area that has received limited attention is understanding how the physical properties of nano-carbon materials influence the final application of asphalt binder. Depending on the specific characteristics of the asphalt binder being studied, this research aims to determine whether nano-carbon (NC) can modify the asphalt binder. A penetration-grade asphalt cement with a 60/70 ratio was prepared with nano-carbon (2, 4, and 6 wt %). First, the properties of the asphalt cement and nano-carbon were examined. The NC-modified asphalt binder was then prepared for testing by heating it to 160°C and mixing with a shear mixer running at 2000 rpm for 30 min. The study also measured the Brookfield rotational viscosity, ductility, and softening point temperature of the NC-modified asphalt binder. Increasing the nano-carbon content altered the rheological properties of the asphalt, increasing stiffness and reducing temperature sensitivity. The addition of 4% NC improved the asphalt binder’s fundamental properties, making it suitable for use in hot climates. Incorporating 4% NC into the hot recycled asphalt mixture resulted in a 32.15% increase in Marshall stability, a 21.42% reduction in flow, preservation of unit weight, and acceptable ranges for air voids and other mix properties. Additionally, the indirect tensile strength (ITS) increased by 37.81%. Overall, adding NC to asphalt mixtures generally enhances their properties, particularly improving rutting resistance at high temperatures by reducing rutting depth by 74% at 60°C.</p>
