Globally, a huge budget expenditure is borne by countries for the smooth operation of road networks. This led to many research works to develop an asphalt mix that is sturdy enough to damage and thereby reduce the maintenance cost. Several studies have indicated enhancement of asphalt mix properties using a range of admixtures and additives. However, most research studies are restricted to a high temperature range of 40°C, 50°C and 60°C. This study aims to evaluate the performance of asphalt concrete mixed with Sb₂O₃ nanomaterial. The dynamic performance of the nano-modified asphalt mix was evaluated at 40°C, 30°C and 20°C. The parameters used for performance evaluation were indirect tensile fatigue test, dynamic creep test and wheel track test. Indirect tensile fatigue test of specimens with Nano Sb₂O₃ had an improved performance by 3-15%. Dynamic creep test results indicated an improved Sb₂O₃ modified asphalt mix performance by 14-26%. The optimum dosage was observed to be 0.5% of Sb₂O₃. However, this study suggests a dosage range of 0.5-0.75%. Further studies regarding the lower temperature range are required to investigate nano-modified asphalt mix performance.
