A single-adding fiber technology only plays a role in improving one performance of asphalt mixture such as high temperature or low water damage performance. Although double-adding fiber-reinforced mixtures are expected to improve overall road performance, existing research still focuses on the analysis single In this study, two representative fibers including lignin (LF) and ceramic (CF) were selected investigate mixtures. The effect different proportions stone matrix (SMA-13) was analyzed via wheel tracking tests, bending test, moisture susceptibility test fatigue etc. results revealed that combined addition LF CF exhibited superior improvements mechanical strength, anti-rutting susceptibility, life compared using either alone. Specifically, SMA LF, both improved 11% dynamic stability, 8.6% low-temperature stress, 2.1% 20% life, respectively. And CF, increased strain 8% while slightly Based efficiency coefficient method, recommended ratio is 1:2, providing more balanced comprehensive enhancement performances. This study provides theoretical reference for engineering application through composite blending, which can effectively enhance service pavement.
