Durability of bridge decks is of vital importance to the Railroad industries. Replacement of deteriorated decks represents a major maintenance item, disrupts operations, and is a routine capital investment. Steel decks, when properly constructed, have proven to be a more durable option than other alternates. AREMA Committee 15 for Steel Structures is currently evaluating the necessary design, fabrication, and construction parameters. Parallel to that effort, a steel deck is under development for used with standard steel rail spans. The decks will be fabricated from plate material and common steel shapes in order to provide a long term, cost effective decking solution. The overall goal is to create a deck system that is equally as durable as the structures they are supported by and can be installed by traditional means, following a new AREMA provision.
