I dont know about any tests, I remember hearing something about it but also heard the rumor of tests was false info.
Seems to me all testing should be NON-Destructive, testing field cured flexural beams specimens in a lab for example.
I’m over my head on this topic. Just thought if you’re putting the bridge in place you might not want people driving under till you’re sure it’s holding. I would do that if I were working on anything at home for example.
