Abstract

Service load deformations may cause deterioration of wearing surfaces and local cracking in concrete slabs and in metal bridges that could impair serviceability and durability, even if self-limiting and not a potential source of collapse. In most recent AASHTO specifications, although the criteria for deflection control are made optional at the discretion of bridge owners or designers, the deflection limitation provisions shall be considered mandatory for orthotropic decks, lightweight decks comprised of metal and concrete, such as filled and partially filled grid decks, and unfilled grid decks composite with reinforced concrete slabs.
