Integral abutments for steel bridges
NettetPrefabricating an integral abutment can save a noticeable amount of time in a bridge construction. Using these integral abutments, deck joints can be eliminated preventing problem areas for deterioration. This … Nettet1. jun. 2005 · Integral-abutment bridges, which do not contain expansion joints, provide a very attractive alternative to the more traditional, stub-abutment bridges that have expansion joints. Jointless bridges have lower construction and maintenance costs than those costs for bridges with expansion joints.
