Question 3

Which inspection method uses electromagnetic induction to assess the condition of reinforcing steel (rebar) in concrete bridge decks without destructive testing?

Accepted Answer

Half-cell potential testing

Answer

Half-cell potential testing measures electrochemical potential differences in concrete to detect the probability of active rebar corrosion non-destructively.

Question 4

A public works manager is selecting a pavement preservation treatment for a road with PCI between 70-85. The MOST cost-effective treatment is typically:

Accepted Answer

Crack sealing and chip seal or microsurfacing
