SIn order to compare and analyze the impact of geothermal regeneration technology on road performance and functionality, the performance of asphalt binder and asphalt mixture before and after geothermal regeneration is tested, and the functionality of the original pavement and recycled pavement is evaluated.SThe results show that the heating process of geothermal regeneration will not significantly age the asphalt binder and affect the gradation. Due to the addition of regenerant, the asphalt binder becomes soft and the low-temperature performance and water stability of asphalt mixture are significantly improved;SThe skid resistance and flatness of the pavement after geothermal regeneration are significantly better than those before regeneration.
