Correlation of Non-Destructive Testing Results to Improve Assessment of Corrosion and Corrosion Damage of a Reinforced Concrete Deck
Periodic monitoring of a 33 year old reinforced concrete bridge deck in Haymarket, Virginia was performed as a part of the Long Term Bridge Performance Program (LTBPP). The bridge carries southbound U.S. Route 15 over Interstate 66. The use of several different non-destructive testing (NDT) methods has allowed monitoring of the progression of corrosion activity and damage over a two year period. The Route 15 bridge was completely surveyed using NDT methods in September of 2009 and again in August 2011. The NDT methods that were utilized for detection of corrosion activity and damage were half-cell potential (HCP), electrical resistivity (ER), ground penetrating radar (GPR), and chain drag (CD)/hammer sounding. Presented are the findings regarding corrosion and deterioration of the deck over time as identified through the use of NDT. Comparison between different NDT methods were made that show relationships between the results of different NDT methods. The comparisons indicated several correlations between methods that identify threshold values and the methods’ ability to identify corrosion at different states of the deterioration process.
