The Composite Arch Bridge System, known as Bridge-In-A-BackpackTM, is a lightweight, corrosion resistant system for short to medium span bridge construction. The system uses FRP composite arch tubes which act as reinforcement and formwork for cast-in-place concrete. The arches are easily transportable, rapidly deployable, and do not require the heavy equipment or large crews needed to handle the weight of traditional construction materials.
The patented FRP system has been tested with advanced structural characterization, predictive modeling, and fatigue testing. Additionally, with environmental durability tests for UV, fire, and abrasion resistance were conducted.
Our innovative composite bridge system:
- Coincides with the American Association of State Highway and Transportation Officials (AASHTO) code
- Lowers construction costs
- Extends structural lifespan up to 100 years
- Serves as a sustainable alternative to traditional construction methods
- Features designs that are engineered to exceed AASHTO load standards for single span bridges from 20 feet to over 65 feet
Advanced Infrastructure Technologies is a privately held company licensed by the University of Maine to produce these bridges.
