MONITOR WARNS OF BRIDGE CORROSION

Approximately 14 percent of bridges in the U.S. have been found to be structurally deficient, and a further one percent become deficient each year. While bridge deterioration is dangerous, repair of these structures is expensive and time-consuming. However, a new electronic monitor that measures five critical factors in rebar decay may be a much-need solution to the widespread problem of bridge decay. Known as the Embedded Corrosion Instrument (ECI), the device can detect signs of corrosion in bridge deck reinforcement. This electronic monitor constitutes a major advance in industry technology, as it integrates processing electronics with sensors, a combination that enables it to use digital communications, rather than analog ones. If the device detects conditions that could lead to cracking, spalling or delamination, a warning is sent to the bridge owner by cellular modem.
