Tying bar for concrete joints

An improved joint construction for transferring stresses across a joint between concrete structures and accommodating for shrinkage or expansion of the concrete structures, the joint defining an axis, the improved joint construction characterized by a plurality of dowel bars embedded in the concrete structures and having sides arranged across the joint in a direction substantially perpendicular to the joint axis and first and second ends, and each bar further having a resilient facing attached to at least one side to provide for movement of the concrete structures in relationship to the bars in a direction substantially perpendicular to the resilient facing and substantially aligned with the joint axis.

An improved dowel bar for transferring stresses across a joint between slabs of a concrete pavement and accommodating for shrinkage or expansion of the slabs, the joint defining an axis, the improved bar having sides and a first and second end, the sides of the bar embedded in the concrete slabs and arranged across the joint in a direction substantially perpendicular to the axis defined by the joint, and the bar further having a resilient facing attached to at least one side of the bar to provide for movement of the concrete slab in relationship to the bar in a direction substantially perpendicular to the resilient facing and substantially aligned with the joint axis.
