DURABILITY OF STEEL-FORMED AND SEALED BRIDGE DECKS
A 2-year research project was carried out to investigate the freeze-thaw durability of concrete bridge decks cast on steel forms, which remain in place after construction, and sealed on the top surface with a waterproof membrane. The long-term durability of the forms was also studied. Laboratory freeze-thaw tests equivalent to a winter season and one winter of outdoor exposure tests were carried out on simulated bridge-deck slabs. These slabs covered all combinations of the following variables: (a) form type (wood and steel) and (b) surface treatment (non, linseed oil, and waterproof membrane). In addition, 25 bridge decks with steel forms and waterproof membranes and 1 bridge deck without steel forms but with a membrane were inspected. The bridge decks ranged in age from 1 to 13 years, and all but six were 8 or more years old. By using a variety of inspection techniques that ranged from visual examination to pluse velocity measurement, it was determined that steel-formed bridge decks with surface sealing are no more prone to freeze-thaw deterioration than wood-fromed decks. Generally, the forms themselves were found to be in good condition when designed for proper deck-surface drainage. /Author/
