Additives in the last decade have been considered by engineers. In this context and in this article by adding different percentages of nano-carbon black marshall experiments, analyze data and plot it was noticed that the addition of these additives increases the resistance of marshall and flow. Nano-carbon black due to scattering property, marshall has a positive effect on resistance. The results show increased resistance marshall nano-carbon black, first reduced and then increased. So that the sample contains 15% nano-carbon black compared to nono-carbon black (base) about 71 % present more resistance. The addition of nano-carbon black in lower percentages of increased mental and higher percentages (10% and above) may lead to mental decline; the sample containing 5% of nano-carbon black about 17% more mental and samples containing nano-carbon black, about 52% mental, 20% less than the reference sample. Due to the nano-carbon black carbon in their chemical structure, although adding it increases mental mix but with an increase in nano-carbon black, carbon black and consequently an increase in mental decline.
