The utility model discloses a composite dowel bar with a hoop. The composite dowel bar comprises a dowel bar, wherein the peripheral surface of the dowel bar is plated with a protection layer; one side, plated with the protection layer, of the dowel bar is coated with a lubricating layer; the periphery, coated with the lubricating layer, of the dowel bar is packaged with a protective sleeve; a protection cap is arranged at one end, packaged with the protective sleeve, of the dowel bar; the hoop is arranged on the peripheral surface of the dowel bar. The composite dowel bar has the beneficial effects that by additionally arranging the dowel bar with the hoop at an expansion joint, the tensile strength of peripheral concrete and the fracture-damage resistance of concrete base structures at the expansion joint are improved, the concrete base structures on two sides of the expansion joint are well stressed together, the load transferring capacity of the expansion joint is improved, the load stress of the concrete
