Prefabricated polyurethane runway material with embedded gridding framework and preparation method of prefabricated polyurethane runway material

The invention belongs to the technical field of runway materials, and particularly relates to a prefabricated polyurethane runway material embedded with a gridding skeleton and a preparation method, and the preparation method comprises the following steps: firstly, preparing an upper-layer polyurethane non-foaming material; preparing a lower layer polyurethane foaming material; then carrying out surface pretreatment on the glass fiber grid; and finally, the pretreated glass fiber grid is placed on the surface of the upper-layer polyurethane non-foaming material, the lower-layer polyurethane foaming material is poured on the surface of the upper-layer polyurethane non-foaming material and the surface of the glass fiber grid through a low-pressure foaming machine, and the prefabricated polyurethane runway material with the embedded gridding framework is obtained after mold closing and curing. The glass fiber grids are added into the prefabricated polyurethane runway material, so that larger gaps of the prefabri
