Sweep (profile to surface path)

hi everyone

How do I replicate the profile on the road? I was a Recruit, I’m doing wrong somewhere and I can’t find the solution.
waiting for your help.
good work everyone

actually, that wasn’t what I meant. I wanted to replicate with 20 cm of this element on the road. for example: Ø10/20 (element)
Thank you for taking the time responding my question with an example.
