ABSTRACT:
An expansion joint system (10) traverses a slot (12) between concrete slabs (14, 16). The system includes nosings (32, 34) overlying an expansible member (40) of unitary construction and made from resilient material. The expansible member has ribbed flaps (42, 44) with holes (48) therethrough. The flaps are attached to the slabs by a layer (46) of adhesive bedding material. The expansible member includes a first segment (69), a second segment (82) and a third segment (96). The segments each include pad portions (70, 84, 98), and web portions (78, 92, 102) extending downward from the pad portions into the slot. The adjacent web portions are joined at locations (106, 112) vertically below the pad portions of the segments.
