A high performance semi-flexible pavement material（SFP） for heavy traffic scenes was developed， and its road performance was systematically tested. The results show that the SFP has extremely excellent strength and deformation resistance， and is less affected by temperature. The strength of the SFP gradually increases and tends to stabilize with age， and the water stability of the SFP is much higher than that of SMA-13 mixture. Under the conditions of high temperature immersion and loading， no peeling is found on the SFP， and the impact of load effect on rutting is much lower than that of SMA-13 mixture. The fatigue performance and low-temperature crack resistance of the SFP are weaker than that of SMA-13 mixture， but significantly superior to ordinary asphalt mixture. The SFP has good long-term durability. The rut depth of semi-flexible pavement structure after 1 million times of accelerated loading is only 1/10 of that of the SMA pavement structure.
