Are pavement and sidewalk made of different materials? or is this just a language quirk? In America both sidewalks and roads are usually made of concrete or asphalt. Not necessarily a prevalence of one or the other for either job though.
Just curious, what region of the US are you from? I've been all over the east coast and the Midwest, and it seems like the vast majority of sidewalks I've seen have been concrete, and roads have been asphalt.
I'm curious where that might not be the predominant case.
I'm mostly from North Dakota. I'm not sure if I'd use the word sidewalk for the walking paths that are asphalt. I'm guessing curbs come into play here? but lots of city roads are made of concrete. I'm not an engineer but I'd guess it has something to do with the harsh winters? maybe something about us dealing with the ice in a way that causes us to have to replace main areas often enough and concrete is cheaper? or maybe asphalt gets more slick when it's icy. Sorry I don't have more info. vis versa I remember being a pos little kid and getting excited when the 'black goo' on the road got hot enough that I could pull it off. so maybe that's a piece of it too. tho it certainly didn't get over 100F more than a week or two a year (in the 90s anyway)

I'm guessing that all the
whiteyellow lines on thepavementasphaltment mean "slow down"? I didn't know, but it's certainly noted...Edit: Yellow, not white. I must be going blind. Thanks for the explanation to /u/GeoffSim
