ABSTRACT OF THE DISCLOSURE A expansion joint system for functioning as an expansion joint between concrete sections of a roadway surface or the like. Such roadway surfaces are normally provided with a slot for accommodating thermal expansion and contraction of the concrete and a boxed-out zone for receiving the expansion joint system. The expansion joint system includes a plate and sealants. The plate is provided with a lower or interior resilient winged section inserted into the slot with wings extending exteriorly to frictionally engage the surfaces of the slot and thereby effect centering and preclude the raising of the plate from the slot. The plate is provided with an upper or exterior section including support surface for resting on the boxed-out surface of the cement segments to thereby preclude the plate from dropping into the slow. A stem couples the upper and lower sections of the plate. A sealant then covers the horizontal support and fills in the boxed-out zone of the concrete. The sealing includes a slab and nosings, the upper surfaces of which lie in a plane with the surface of the concrete sections whereby vehicular traffic or the like may move thereacross.
