New plans should be used to improve quality and to increase productivity and durability of conventional pavements. In this investigation, it has been attempted to promote technical characteristics of bitumen using carbon nanotubes as an additive. Wet and dry process methods are most practical ways of mixing CNF in AC. It was decided that the best method to adopt for this investigation was the dry process. In this study thermal and ductility properties of modified bitumen by 0.1, 0.5, and 1% carbon nano-tube content in bitumen were evaluated considering bitumen penetration, softening point, and ductility tests, then the results were compared to those of unmodified bitumen. It was found that adding carbon nano-tubes effects on thermal properties of bitumen by increasing the softening point and decreasing the bitumen penetration. It was also shown that bitumen ductility decreases by carbon nano-tubes modification process.
