High modulus asphalt mixture has been applied in heavy-duty pavement due to its excellent comprehensive perform-ance.Reclaimed asphalt pavement(RAP)is a waste material that is milled out during road maintenance and repair.The dy-namic modulus,high temperature stability,low temperature stability,water stability,and fatigue performance of high modulus recycled asphalt mixture prepared by adding hard asphalt particles and high modulus recycled asphalt mixture remixed with RAP were tested.The experimental results show that the high modulus recycled asphalt mixture based on high content RAP exhibits good high-temperature rutting resistance,low-temperature cracking resistance,water damage resistance,and fatigue performance.
