Agom bridge expansion joints are structural components designed to provide smooth passage over the gap between adjacent sides of a deck joint, while also permitting relative translation and/or rotation of the two sides of a bridge deck (deck movement joint).
AGOM elastomeric reinforced joints for roads, called AGFLEXJ, are designed to enable service displacements up to 330 mm (±165 mm) with respect to the bridge decks they are fastened to. Entirely waterproof, they are secured to the structure with suitable anchor bolts. The deformable rubber elements are vulcanised with rolled steel reinforcements made up of two angular plates and a bridge plate. AGFLEXJ, joints also allow displacement of the structure’s parts relative to each other in any direction.
Expansion joint type AGFLEX J50 is designed to enable service displacements up to 50 mm (±25 mm).
It can support also transversal movements up to ±17 mm.
