resistant to salt and frost

Composite is resistant to salt and frost, and can be very advantageous compared to concrete and steel. The weight is of the essence. A composite bridge has a weight that is 40% lower than steel, and 30% lower than concrete.

The environmental benefits are also optimal. In a study, in which the accumulated energy level and C02 footprint of different types of bridges are compared, the results show that composite materials have greater environmental benefits compared to steel and concrete:

Material choice:The accumulated energy content:
(Prod. of raw materials, prod. process, transport, disassembly and recirculation)
CO2 footprints:
(Total content of GHG through the lifecycle)
Steel bridge3380 GJ178 tons CO2
Composite bridge w/ carbon fiber2210 GJ108 tons CO2
Concrete bridge1978 GJ145 tons CO2
Composite bridge w/glassfiber652 GJ75 tons CO2
