The aim of the research was to evaluate the performance of Hot Mix Asphalt (HMA) and bitumen by modifying bitumen with nano materials according to Superpave (TM) mix design procedure. In this research, bitumen was modified by Multi-Walled Carbon Nanotube (MWCNT) and Carbon Nanotubes Doped with 50 wt% SiO2 Nanopowder (SiO(2)dopedCNT). Nano materials were mixed with base bitumen at contents of 1, 3 and 5% by weight. Rutting and fatigue performance of bitumen was determined. HMA is prepared with nano modified bitumen at optimum binder content (OBC). Moisture susceptibility of modified hot mix asphalt was evaluated according to Modified Lottman test procedure. Nano modified bitumens were also evaluated by scanning electron microscopy whether the modification was uniform or not.
