Abstract
The Iowa Department of Transportation initiated this research
to evaluate the reliability, benefit and application of the corrosion
detection device. Through field testing prior to repair projects
and inspection at the time of repair, the device was shown
to be reliable.
With the reliability established, twelve additional devices
were purchased so that this evaluation procedure could be used
routinely on all repair projects. The corrosion detection device
was established as a means for determining concrete removal for
repair. Removal of the concrete down to the top reinforcing steel
is required for all areas exhibiting electrical potentials greater
than 0.45 Volt.
It was determined that the corrosion detection device was
not applicable to membrane testing.
The corrosion detection device has been used to evaluate corrosion
of reinforcing steel in continuously reinforced concrete
pavement
