ABSTRACT:
An expansion joint is shown for use in joining adjacent concrete sections separated by an expansion slot such as in a roadway having concrete sections and a slot therebetween. The joint includes a preformed longitudinal sealing element which is formed of a resilient material and installed within the slot. An initially flowable adhesive material is applied between the sealing element and opposing side surfaces of the concrete sections making up the joint. The moduli of elasticity of the adhesive material and sealing element are selected so that forces exerted upon the joint by expansion and contraction of the concrete sections result in movement of the central sealing element, rather than exerting strain upon the adhesive bond.
