ABSTRACT OF THE DISCLOSURE An expansion joint and form for concrete floors, consisting of a free-standing assembly comprising a vertical asphaltic board, a metallic panel flatly abutting against the asphaltic board, and a number of load transfer dowels or rods slidingly passing horizontally through the board and panel to extend on each side of the panel and board. The rod partially engages at one end a sleeve and one rod section is covered with grease. After fresh concrete is successively poured on each side of the expansion joint, the concrete will harden unto the board, the panel and the sleeve exclusively of the rod section covered with grease. Hence, the rod will be movable relative to the sleeve and surrounding concrete slab, allowing for relative horizontal displacement of the pair of proximate concrete slabs
