This is an example of early detection of deterioration that is difficult to notice from the appearance through regular inspections, leading to repairs.
During a regular inspection of a certain bridge, a sound test was conducted on a bridge pier that appeared to be in good condition externally, and a large-scale delamination of the concrete was discovered. If left unaddressed, there was a risk of spalling and exposure of the rebar, but early detection allowed for a reduction in the scale of repairs. This case is a typical example that demonstrates the importance of close inspections and sound tests. Regular inspections and detailed records enable the early detection of damage that is difficult to confirm through visual inspection alone.
