| Abstract: | The effect of aging temperature on the performance of warm mix asphalt was analyzed,and the optimal mixing temperature of warm mix asphalt was explored by using the viscosity-temperature curve and the method of controlling the void ratio.The optimal film oven aging temperature of warm mix asphalt was determined to be 154℃.The aging performance of warm mix asphalt was evaluated at 154℃,which could be constructed at a lower temperature,and the performance of the mixed asphalt met the requirements of relevant indexes,which was more energy-saving and environmentally friendly. |
