Evaluation of Performance Properties of Asphalt Mixtures Modified By Carbon Nano Tube

The rheological properties directly affect the mechanical properties of hot mixtures at different temperatures. Recent research has shown that the use of nano-materials results in improving functional properties. In this study, some tests have been done to compare the performance properties of the modified asphalt mixtures with carbon nanotubes and no additives. Mechanical properties of asphalt were evaluated including resilient modulus, creep behavior and fatigue performance. The results of this study show a significant improvement in the mechanical properties of asphalt mixture containing the carbon nanotube, against the phenomenon of fatigue and constant deformation compared to the conventional asphalt mixture.
