| REPRESENTATIVE
EXODERMIC™ PROJECTS
One reason Exodermic™ decks
are specified is because they are the cost effective choice
for projects where a reduction in deck deadload has a significant
structural benefit – achieving
a required load rating without substantial reconstruction
or replacement of the superstructure or substructure, for
example.
Many types of bridges have benefited from the light weight
of Exodermic™ decks: arch, deck
truss, through truss, pony
truss, deck girder, movable
bridges.
Exodermic™ decks are
also specified where speed of construction is important.
Both precast and cast-in-place Exodermic™
decks
are generally significantly faster to construct than
conventional cast-in-place reinforced concrete decks.
Taking advantage
of this capability has been used to:

is a directory of information
on recent representative projects which have
used the Exodermic™ design. In
virtually all cases, savings in time, materials, money,
and traffic
interruption were realized. Many projects demonstrated
Exodermic™'s unique advantages in the the face of special
deck design requirements or restrictions. Click on any
