The utility model discloses a novel steel-concrete combined bridge deck, belongs to the technical field of bridge engineering, and solves the problems of lower rigidity and poorer performance of an orthotropic steel bridge deck system. The combined panel comprises a steel beam and a combined panel, the combined panel comprises a steel bridge deck, a concrete surface layer and an asphalt concrete surface layer, the steel bridge deck is connected above the steel beam, a plurality of groups of connecting pieces are connected on the steel bridge deck side by side, a plurality of reinforcing steel bars are connected between the connecting pieces side by side, and concrete is poured on the steel bridge deck, the connecting pieces and the reinforcing steel bars to form the concrete surface layer. And the asphalt concrete surface layer is positioned above the concrete surface layer. The reinforcing steel bars are connected into a whole through the multiple sets of connecting pieces, the integrity of the steel structu
