I’ve tried using it over the years but I never liked it because there was no information. So last night I looked at my local city and there is almost no information at all. I spent a few hours last night adding buildings and restaurants and removing incorrect items. It was actually kind of fun and therapeutic and I plan to do more of it tonight. My girlfriend thinks it’s dumb and I’m wasting my time because Google maps and Apple maps and Bing maps exists but she just doesn’t understand open source.
Edit: Apologies, I just realized this question is not Linux specific.
Asphalt can be on top of concrete.
But From my experience concreet normally has a visible splits between segments every few meters and is almost always way lighter in color.

I’m not a specialist but to me, it is all about road quality, asfalt when you can safely drive and it’s very smooth ride like you drive in the air, while co concrete you can drive well but there are clearly visible or audible bumps, so for me the actual material (or mix of them) doesn’t matter, if they can make classy and safe to drive road with glass or anything else should not matter.
I think I got it figured out. It’s pretty obvious when I compare them side by side.
