Nanotechnology is one of the most important research areas and is presented in the vastfields of knowledge such as road construction industry has been surrounded. This paper hasfocused on the potential benefits of nano particles for modification of asphalt mixtures.Nano Fe2O3 due to its unique properties can improve the dynamic characteristics of stonemastic asphalt. Fatigue life of asphaltic samples is determined with indirect tensile fatiguetests by using of UTM Asphalt Tester. The results show that fatigue life of modified asphaltmixtures in compare with conventional mix is significantly increased.
