Abstract: In the context of the wide demand of high quality of bitumen, this research was initiated with the objective of enhancing the asphalt mix properties. Variable additives percentages of nanomaterial and polymer material were investigated, experimentally, in order to determine their effect on asphalt properties. Three nano materials (i.e. nano-silica, nano0kaolinite and nano-montmorlinit) and three polymer materials were considered (i.e. SBS, polypropylene, and polyethylene). Modified specimens (with 1, 3, 5, 7, and 9% of nano and polymer material) were prepared. Rheological properties tests were conducted (i.e. penetration, softening, flash point and viscosity). In addition, mechanical properties tests were carried out (i.e. Marshall, compression, and indirect tensile tests). Results were obtained and analyzed. They indicted that additives enhanced rheological and mechanical properties of asphalt mix.
