Several advantages of fiberglass bridge deck

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.
