Subsurface Imaging of Corrosion in Painted Steel Bridges
According to a comprehensive study carried out by CCTechnologies in 1998, cost of corrosion to US economy was 3 % of the GDP in 1998 amounting to $276 Billions (FHWA-‐ RD-‐01-‐156). From that amount, $121 billion was spent on corrosion control, from which $107 billion was spent on protective coatings. It was reported that better corrosion protection could save up 40% of that cost.
