Abstract

FIber optic sensors have repeatedly been shown to provide measurement capabilities of parameters within such reinforced concrete structures. Development of a fiber optic chloride sensor capable of being embedded within a roadway or bridge deck is reported. Once the specific chemistry of the fiber optic sensor was developed and tested, multiple iterations occurred in order to result in a sensor system capable of being embedded into roadway bridges. During the summer and fall of 1997, a total of 64 fiber optic sensors were then embedded into 3 roadway bridges which spanned rivers in northern Vermont. Installation details as well as results are presented.
