For designers and bridge builders, the GFRP
deck has many benefits, providing dynamic solutions and long-term benefits.
Light weight
The weight of the FRP deck is only 10-20% of
that of the reinforced concrete deck of the same structure.Replacing the
concrete deck with the fiberglass bridge deck can significantly reduce the
self-weight.In the new construction, the lighter self-weight can be converted
into saving the whole structure, and the size of the structural component and
the basic component can be reduced accordingly.Because FRP deck panels
typically weigh less than 6,000 pounds each, more convenient equipment can be
installed on deck.A excavator or excavator at the site is sufficient.Expensive
cranes are not required, thus reducing installation costs in most cases and
occasional overhead power line restrictions are necessary to use cranes.
Corrosion-resistant steel corrosion is the
main reason for premature deterioration of concrete bridge deck.The use of road
de-icing salt, combined with higher than expected flow loads, accelerated the
corrosion.FRP bridge panels are a good alternative to traditional materials due
to the fact that fiberglass materials are not easy to corrode.The benefits are
more important in cold weather or coastal areas.FRP materials have been proven
to be highly durable in corrosive chemical environments and not degraded for 50
years.This provides a solid foundation for a fiberglass deck with a life
expectancy of 75-100 years.
The advantages of installing quick bridge
panels in the factory and transporting them to the bridge site over concrete
casting are as follows: quality can be closely monitored in a controlled
environment;To reduce the impact of weather delays;Most significantly, the downtime
at the bridge can be greatly reduced.Once the superstructure is ready,
prefabricated FRP bridge deck panels can be quickly installed, even erect
template, compared with the traditional place of reinforcement, pouring and
curing of concrete, and eliminate build casting to deck such human cost.
High strength composite board has high
strength and very high safety factor.As the FRP material is not used as hard
steel and steel, rigidity performance requires the design of the FRP deck to be
driven.Deflection criteria have become the most important performance
indicators.The deflection criterion for FRP bridge deck is often more
conservative than that for concrete bridge deck - in part because FRP is still
considered new material because users want to minimize surface wear and
cracking.However, the static test of FRP bridge deck clearly shows that the
bridge deck greatly exceeds the specified performance requirements and provides
high safety factors.
Reduce the cost of life cycle
Corrosion resistance makes FRP decorative
bridge deck maintenance very low, which reduces future maintenance costs.This
also means that the FRP deck will last longer than traditional materials.All of
these reduce the life cycle cost of using the FRP deck.
