There are over 578,000 bridges on public roads in the United States and more than 112,000 of them are rated as substandard either through deterioration or obsolescence. Recently, fiber reinforced polymer (FRP) composites have been investigated for building bridges due to advantages such as: reduced weight, decreased effects from environment, and speed of installation. Luna Innovations has been working closely with researchers at Atlantic Research Corporation (ARC) to develop and implement an embeddable fiber optic health monitoring system to monitor strain in composite bridge decks over time. During this research, Luna Innovations successfully embedded fiber optic strain sensors in three composite bridge decks fabricated by ARC. Strain data was recorded during 3-point bend testing of two of the bridge decks. The third bridge deck was placed at a Beta test site in November of 1999 where the strain sensors have been monitored periodically.
