Abstract With development of nanotechnology, the application of nano materials to improve the bitumen became a focus of many researchers. The manipulation of material composition in nanoscale has led to creation of macro-materials with better mechanical performance and durability. However, the influence of nano materials to bitumen behaviour is still unclear. The objective of this research was to determine the influence of nano materials to rheological properties of bitumen. Based on literature analysis the most promising nano-materials and their composition were selected for experimental research. The rheological properties were determined for 29 specimens produced from two bitumen (non-aged 70/100 and PMB 45/80-55) and three nano-materials (nano SiO2, nano TiO2 and nano ZnO). The dynamic shear modulus and phase angle, fatigue performance and non-recoverable creep compliance parameters were determined with Dynamic Shear Rheometer. Statistical analysis was conducted to relate the bitumen modification variables with the rheological properties. The research results showed that nano materials improve bitumen resistance to permanent deformation, however, the excessive amount of nano materials in bitumen may result lower bitumen resistant to fatigue.
