ABSTRACT:
A sleeve assembly system, a concrete dowel slab joint system, a method 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, and a concrete slab including a plurality of concrete dowel slab joint systems are provided. The concrete dowel slab joint system comprises the sleeve assembly for receiving and maintaining the dowel bar therewithin. The sleeve assembly is designed so that the dowel bar does not transmit substantial shear stresses to the concrete during the contraction and expansion of the concrete. A pair of bracket members, located on an underlying surface, support the sleeve assembly and the dowel bar above the underlying surface.
