Nanotechnology is the most versatile field because its application covers science, research and technology. NanomaterialÂs enhanced surface to volume ratio has shown different properties frombulkmaterials. The aimof this study to investigate the properties of asphalt by blending it with TiO2 nanoparticles. TiO2 nanoparticles are fabricated by hydrothermal method and well characterized by X-ray diffraction technique.Tio2 nanoparticles (1.0%byweight) were added in asphalt. Themixture was homogeneous by stirring mechanically at 1630C. The following rheological properties like penetration, softening point and ductility of asphalt were measured with and without doping of TiO2 nanoparticles at laboratory scale. The results of the experiments indicated that the addition of TiO2 nanoparticles was helpful in increasing the hardness, viscosity grade and ductility of the binder.
