The invention discloses an FRP (Fiber Reinforce Plastic)-concrete combined bridge deck which comprises single width FRP plates. A plurality of single width FRP plates are connected to form an assembling FRP plate with required size; bilateral sides of every single width FRP plate are provided reversing L-shaped ribs; T-shaped ribs are arranged between the reversing L-shaped ribs; the T-shaped ribs are connected with an upper surface of the bottom of every single width FRP plate; transversely connected FRP ribs are arranged inside the reversing L-shaped ribs and the T-shaped ribs; concretes are directly poured on the assembling FRP plate to form into the FRP-concrete combined bridge deck; and an upper portion of every T-shaped rib is embedded into the concrete. The FRP-concrete combined bridge deck has the advantages of being capable of effectively increasing service life and bearing capability of the bridge deck, enabling the self weight of a structure to be reduced, reducing maintenance costs of the structur
