Steel - Correct Answer ✔✔ ______ decks are found on many older bridges and
movable bridges.
Timber - Correct Answer ✔✔ _______ decks use glue or nail laminated connections to
transmit loads to the superstructure.
, Concrete - Correct Answer ✔✔ ________ decks are the most common type of deck due
to variable shapes, sizes, and construction methods.
Timber - Correct Answer ✔✔ What bridge deck material is desirable for its resistance to
decaying agents?
Timber - Correct Answer ✔✔ What bridge deck material can withstand relatively large
loads over a short period of time?
Monolithic - Correct Answer ✔✔ a member that has been cast as one unit, without joints
or seams.
PS deck panels with CIP topping - Correct Answer ✔✔ What type of concrete deck has
panels that are cast offsite but do not include a wearing surface when installed?
Precast conventionally reinforced - Correct Answer ✔✔ What type of concrete deck has
panels cast and cured offsite and reinforced with mild steel?
Tensile and shear - Correct Answer ✔✔ What kinds of forces does steel resist?
Primary reinforcement - Correct Answer ✔✔ Provides tensile and shear strength in a
concrete deck
Secondary reinforcement - Correct Answer ✔✔ Used for temperature and shrinkage in
a concrete deck
Primary - Correct Answer ✔✔ _______ reinforcement is placed transversely across the
deck
Secondary - Correct Answer ✔✔ ________ reinforcement is placed parallel with beams
and stringers
Positive Moment Tension - Correct Answer ✔✔ _______ ________ _______ is in
between beams at the bottom of the deck.

beams at the top of the deck.
Steel decks - Correct Answer ✔✔ This type of deck includes orthotropic and grid decks.
Orthotropic decks - Correct Answer ✔✔ Flat, thin steel plate stiffened with closely
spaced longitudinal steel ribs and wearing surface is applied on top of the steel plate.
Grid deck - Correct Answer ✔✔ This type of deck is most often present on moveable
and rehabilitated bridges, for reduced dead load and easier installation.
