The invention discloses a semi-flexible pavement material, a preparation method therefor and a semi-flexible pavement. The semi-flexible pavement material is prepared from the raw materials, i.e., a cement grouting material and an asphalt mixture in parts by mass, wherein the cement grouting material contains 15-20 parts of cement, 8-10 parts of emulsified asphalt, 0.03-0.06 part of water reducing agent, 0.06-0.2 part of polypropylene fibers, 10-15 parts of mineral powder, 30-35 parts of sand, 8-10 parts of fly ash, 0.06-0.12 part of expanding agent and 0.03-0.06 part of interface modifier. According to the semi-flexible pavement material disclosed by the invention, the cement grouting material is added with the emulsified asphalt, the fly ash, the polypropylene fibers, the mineral powder, the water reducing agent, the expanding agent and the interface modifier which are mutually compounded and are in synergism, so that the cement grouting material can be easily subjected to dry shrinkage, the condition that the interfacial adhesion performance of cement-asphalt concrete is poor is improved, and thus, the crack resistance is improved. In addition, asphalt of the asphalt mixture is rubber asphalt, so that the crack resistance and adhesion property of the asphalt mixture are improved.
