Civil engineering graduate student Hannah Loring and her adviser Bill Davids are working to develop an easily installed "fiber-reinforced polymer flexural retrofit system" to reinforce aging concrete flat-slab bridges. The system uses glass and carbon composites made into thin strips and placed on the underside of the bridge. The strips boost the span's strength by 30%. "We're giving a low-cost alternative for the short term that would increase the strength and durability of the bridge, prevent it from having weight [limits] posted, and allow the bridge to remain safe," said Loring.
