[CHenry]

No

in the road they usually put a hard nail and washer if i remember correctly

No, not for initial survey. Blue tops are elevation for overlays.

And blue tops nailed into the pavement, yes, for elevation. I wasn't a construction surveyor so my knowledge of that is limited but I did location surveys like shown above and then designed plans based on those surveys.
20+56.5 might be to mark the location of a driveway, telephone pedestal or maybe a headwall on a drainage structure. We would locate anything. The note in the book would give a station and offset distance left or right.

No, I knew what you were talking about with grading elevation but I never did that kind of survey so im no expert by far.
But I've designed over 1000 highway projects and they all start with a location survey, so I do consider myself an expert in that area. The 1 year I did location survey helped me be a better designer.
But im retired and losing much of that knowledge by the day.

I loved my job, but working for ODOT, the politics were getting crazy as I moved up in management and I burned out.
