A plurality of sleeve members for receiving and maintaining a dowel bar therewithin can be provided so that the dowel bar does not transmit substantial shear stresses to the concrete during the contraction and expansion of the concrete. The sleeve members can comprise (a) at least one hollow interior compartment for receiving and supporting said dowel bar, and (b) at least one aperture for receiving a bracket member. The dowel bar can have a tapered configuration and a pair of end sections. The dowel bar can be located within the hollow interior compartment for maintaining adjacent sections of concrete in alignment during contraction and expansion of the concrete, and for transferring shear stresses and bending moments across a joint formed between adjacent concrete slabs. The dowel bar can move in a lateral and/or longitudinal path within the hollow interior compartment and exerting interactive forces in response to the expansion and contraction of the concrete. A plurality of bracket members located on an underlying surface can support the sleeve members and the dowel bar above the underlying surface.
