Characterization of CNTs-modified HMA’s mechanical properties

The rheological properties and thermal sensitivity of asphalt binder directly affect the mechanical properties of hot mix asphalt (HMA) at different temperatures. Conducted researches have proved that nano materials can improve HMA’s properties as modifier, if well mixed in the asphalt binder. In this study some tests are done to compare functional properties of neat and carbon nanotubes (CNTs)-modified asphalt mixtures. As the first step, the...
