The utility model discloses an airfield pavement structure constructed by additionally paving an asphalt surface layer on an old cement concrete pavement. The airfield pavement structure sequentiallycomprises an old cement concrete pavement structure (0), a stress absorption layer (1), an asphalt concrete lower surface layer (2), a first adhesive layer (3), an asphalt concrete middle surface layer (4), a second adhesive layer (5) and an asphalt concrete upper surface layer (6) from bottom to top. By adopting surface layer structures such as the modified asphalt and the epoxy asphalt, the high-temperature stability, the water stability and the anti-fatigue property of the pavement are improved. According to the utility model, a new pavement is constructed on the original old cement concrete pavement, the construction is rapid, the asphalt flexible surface layer can be additionally paved without stopping navigation, and the requirements of airports are greatly met.
