Abstract

Many light poles and signposts are embedded in asphalt or concrete. Because the bases of poles set in asphalt or concrete are susceptible to corrosion below ground level, there is a need for inspection techniques to evaluate corrosion in the underground portions of pole bases. High-sensitivity magnetic detection was developed for nondestructive inspection of embedded potion of corrosion a probe device equipped with two probes set at a downward angle of 30° in order to evaluate corrosion light pole bases. The two probes are provided to estimate the amount of reduction in plate thickness due to corrosion and the location of such corrosion. Nondestructive high-sensitivity magnetic inspection is capable of performing measurement in just a few seconds per point, and this investigation has demonstrated that it can be used in screening for corrosion in portions of steel members that are embedded in concrete.
