Subsurface Imaging of Corrosion in Painted Steel Bridges
According to a comprehensive study conducted in 1998 by CC Technologies, corrosion to the US economy was $276 billion or 3 % of the 1998 GDP (FHWA-RD-01-156). From that amount, $121 billion was spent on corrosion control and $107 billion was spent on protective coatings alone. CC Technologies reported that better corrosion protection could save up 40% of that cost.
