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.

选择Sb ₂ O ₃纳米颗粒是因为它有望减少对沥青的老化影响，是一种尚未在文献中研究的新型材料。沥青被三氧化二锑（Sb ₂ O ₃）纳米颗粒改性。研究了 Sb ₂ O ₃改性沥青的车辙性能和热拌沥青 (HMA) 的性能。进行了多重应力蠕变恢复 (MSCR) 测试。HMA 混合物使用间接拉伸强度 (IDT) 测试进行测试。在进行汉堡车轮跟踪 (HWT) 测试以确定 HMA 混合物的车辙性能之前，将 HMA 混合物在烘箱中进行短期和长期老化。老化后，Sb ₂ O根据沥青和 HMA 测试的结果，₃改性沥青变得更具抵抗力。结果，百分之三的 Sb ₂ O ₃改性沥青具有更好的性能，类似于 Jnr 和 R%。车辙深度为 4.3 mm 的3% Sb ₂ O ₃改性沥青的车辙性能最佳。
