FRP Composites for Bridge Decks and Superstructures: State of the Practice in the U.S.

In the U.S., fiber reinforced polymer (FRP) composite materials have been in service on public infrastructure facilities as bridge decks and superstructures for over ten years.

The main activity of Global Basalt Engineering LLC is creation of effective productions on release of continuous basalt fiber (СBF) with technologies of the last generation and composites on the basis of СBF (Basalt Fiber-Reinforced Polymer Composites as BFRP).

While the structural performance of these 100+ bridges has generally been satisfactory, some issues have given bridge owners and their consultant engineers reason to hold back a on wider acceptance and use of these new materials.

Here the authors give some specific examples of completed projects, explain the deficiencies that need to be explored further before composites can compete with conventional materials, and point to some promising technologies that may spark a renewed interest in these materials.
