Description / Abstract:
This guide presents considerations to take in the design and a
summary of construction practices for conventionally reinforced
concrete highway bridge decks. Such decks are typically supported
by multiple simple- or continuous-span steel or prestressed
concrete girders, or integral reinforced concrete members. The
service-life performance of concrete bridge decks, including
maintenance, repair, and rehabilitation needs, is directly related
to the care exercised from preconstruction through the
post-construction period. Recommendations are presented for design
and durability considerations, concrete materials, reinforcement,
placing, finishing and curing, and the use of overlays.
Although some performance and durability factors discussed may
be applicable, design and construction of prestressed bridge decks
are presently beyond the scope of this guide. Thus, prestressing
steel is not included in the reinforcement section. Guidance for
the design of prestressed bridge decks is being developed elsewhere
(Swartz and Schokker 2008).
