Sb2O3 nanoparticle was selected as it is expected to reduce the aging effect on bitumen, and is a novel material hasn’t studied yet in the literature. Bitumen was modified by antimony trioxide (Sb2O3) nano particle. The rutting performance of Sb2O3 modified bitumen and the performance of Hot Mix Asphalt (HMA) was investigated. Multiple stress creep recovery (MSCR) test was performed. HMA mixtures were tested using the Indirect Tensile Strength (IDT) test. HMA mixtures were aged in the oven for short and long-term aging before conducting Hamburg Wheel Tracking (HWT) test to determine the rutting performance of the HMA mixtures. After aging, Sb2O3 modified bitumen becomes more resistive according to the results of both the bitumen and HMA tests. As a result, three percent Sb2O3 modified bitumen had better performance similar Jnr and R%. The best rutting performance was determined for 3% Sb2O3 modified bitumen with 4.3 mm rut depth. |
