The utility model relates to the technical field of runway structures, in particular to a semi-prefabricated runway structure which comprises a bonding layer, the top of the bonding layer is fixedly connected with a substrate layer, the substrate layer is of a grid structure, and the top of the substrate layer is fixedly connected with a waterproof layer. The utility model has the advantages that the waterproof layer is particularly a thermoplastic polyurethane elastomer rubber layer which is compact, but still keeps better elasticity, has outstanding bearing capacity, impact resistance and shock absorption performance, is not easy to permeate water vapor, is oil-resistant, water-resistant and mould-resistant, prevents the water vapor from being contacted with the bonding layer, and ensures the service life of the bonding layer. Meanwhile, the waterproof performance of the semi-prefabricated runway is further improved through the design of the waterproof coating, the waterproof coating is specifically a polyu
