New corrosion-resistant concrete reinforcement wins AASHTO Sweet 16 award for extending life of coastal bridges

A group of Georgia Tech and Georgia Department of Transportation researchers after they received an AASHTO Sweet Sixteen award from DOT Commissioner Russell McMurry Dec. 8. Their work on corrosion-resistant concrete piles for marine environments has been used on bridges in Georgia and is being tested for use in nearby states.

A leading standards-setting transportation organization has named a project by Georgia Tech and Georgia Department of Transportation researchers one of the year’s most valuable. The work developed a new steel to reinforce concrete bridge piles in marine environments that withstands corrosion and lasts well beyond the expected 100-year lifespan of the structures.

Kahn to Chronicle: Corrosion monitoring system for Bay Bridge a good idea

Screen shot of the San Francisco Chronicle article that includes Professor Emeritus Lawrence Kahn.

A relatively inexpensive monitoring system could be installed in the San Francisco-Oakland Bay Bridge to easily detect signs of corrosion in the eastern span’s foundation and warn engineers. That’s what School of Civil and Environmental Engineering Professor Emeritus Lawrence Kahn told the San Francisco Chronicle November 21.
