Abstract
The purpose of this research is to develop a non-destructive inspection method that utilizes thermoelasticity testing for Post-Tensioned (PT) bridges that contain flexible fillers (FF’s) for corrosion protection. PT bridges have been designed historically to contain cementitious grouts (CG’s) to resist corrosion. However, CG duct bridge systems have proven to be prevalent to tendon corrosion which induce concrete cracking. The Florida Department of Transportation (FDOT) began implementing the use of FF’s for corrosion protection in PT tendons used in Florida bridge structures in 2016. FF’s serve as coatings in unbonded PT systems to protect steel tendons and fill voids which protect the system from water. FF’s are comprised of a greasy wax consistency, which coat the tendons. Contrary to FF’s, CG internal duct systems result in a bonded system, subsequently making replacement impracticable.
