This paper focuses on the experimental study of the factors affecting the road performance of recycled asphalt mixtures,summarizes the performance requirements of the experimental old materials new materials,and the key points of the orthogonal experimental design for the performance of recycled asphalt mixtures.The results show that the high temperature stability of recycled asphalt mixture is most affected by RAP content,and the low temperature crack resistance and water stability are most affected by asphalt content.
