Abstract
An improved dowel or tying bar and joint construction for transferring stresses across a joint between concrete slabs or structures and accommodating for shrinkage and expansion of concrete. The bar has a resilient facing attached to at least one side of the bar so that the concrete slab or structure can move in relationship to the bar in a direction substantially perpendicular to the resilient facing. The bar is arranged across the joint in a direction substantially perpendicular to the axis defined by the joint.
