I thought the main issue with cold weather climates isn't that your surface gets cold, but that it oscillates between freezing and thawing. The growth of ice crystals eats away at everything, the surface thaws and let's in more water, and the process repeats. You wouldn't necessarily want a surface that heats well if you are just below the freezing point.

asphalt also kinda needs to be driven on frequently to function best without cracks, etc., so that's another reason you don't see it as much in driveways

There's that plus the large amount of salt that gets dumped on the roadways. Which Tesla in all if its Silicon Valley wisdom totally did not consider when designing.

The neat thing about concrete is that it is durable enough that overnight repairs doesn't need to be a selling point.

I have no idea how true this is, but I remember hearing that asphalt mostly exists to be cheap to place and expensive to maintain.

Concrete can buckle in the right conditions. This was a major problem on one of the roads I would take, so they'd have to take a "panel" out to fix it.

What's with Americans and roads made out of concrete plates? What have you got against asphalt?

They aren't "plates" per se. It's one pour, but they put deep lines in them to allow the concrete to expand and contract without cracking itself into a giant mess, especially in climates where the temperatures range from freezing to stupid hot (30c+/80F+)

Concrete and Asphalt both have their uses. On regular roads it really comes down (at least here in Ohio) to which one is cheaper to build with. Concrete has less stringent base requirements than asphalt which needs a good proper stone base otherwise the whole thing fails. Concrete also lasts longer when placed well but it’s also easy to gently caress up placement and have it start cracking bad in a few years. Asphalt is more flexible and needs more maintenance but it’s “cheaper” to just mill out and put a new course in when needed as long as the base is good. We just had a full reconstruction this year where we replaced a concrete base intersection (2” asphalt overlay with 10” concrete base) to our standard asphalt profile (1” smooth surface / 2” intermediate / 3” base asphalt / 8” stone I think it was) but we ended up loving up because we didn’t account on the sub grade to be utter and complete poo poo so we ended up eating a ton of costs on undercuts and subgrade repairs.

Don’t skip out on the geotechnical exploration before a project, folks.

Over here in Germany Asphalt is more expensive than concrete but offers superior road characteristics (if maintained obviously)

Concrete also has the massive risk of blow ups that cause multiple lethal accidents every summer.



Imagine this suddenly appears in front of you while you travel at 200+ km/h (worst case on a bike)

The superior highway combination is a concrete right lane for durability under truck loads and an asphalt left lane for passing vehicles at higher velocities

luv 2 get custom titles from a forum that goes into revolt when its told to stop using a bad word.
In Germany it makes sense to build roads that can last a decade. In the US where budgeting is short sighted, we build roads that can last one winter, then require extensive rebuilding. This is cheaper up front and keeps politically connected road building companies in business.

The transportation budgets are always the first things to get slashed, because their ill effects of slashing them don't show up for years down the line. Come on man.

That's not even getting into side streets where the state or county boards can't throw their weight around that are crumbling into gravel, because to fix them it would require a tax increase AND WE CAN'T HAVE THAT

Seriously, most small towns haven't seen an actual road budgets increase since the 80s. Where I live the side streets have never gotten roadwork done besides some tar. Asphalt will last a long time if it's done correctly and if not will only be fixed if it kills people.

I agree that asphalt done properly will last, but that's also in climates that don't have freeze/thaw cycles like the upper Midwest does. The utter refusal to fix the roads comes solely from the fact that it costs money, and the budgets around here got slashed so badly that they need a tax increase to fix the roads.

e: the driveway I have is pretty old, and has lasted pretty well, but it also doesn't see heavy traffic that interacts with those cycles. So it's a combination of a lot of factors, but the fact remains that the roads aren't lovely because of some government corruption, it's because of shortsightedness and an abject refusal on the constituents to raise the money to fix them.

White paint is suspect to easier corrosion as well as in paint corrosion due to the processing of the titanium oxide that makes up the paint pigments.

Ford had a super expensive recall about that a few years ago with their transporters and commercial line of vehicles.

Rusty white paint can also be translated as being cheapskates at the paint both.

one fun tradeoff of asphalt in climates that freeze is the really amazing potholes that form, due to how water seeps into the (porous) asphalt as temperatures rise and fall. i ended up with a car repair bill of like $450 last winter, due to not noticing quickly enough that there was a nice big fresh crater on one of my local streets

Older paint that's not water based. And no paint without clear coat. Also older paints because they are thicker and will allow you heavier and more paint corrections before you run the risk of running out of clear coat (this won't happen just because you buff out some holograms with ultra fine or anti holo polish - think more that there's a limited number of times you can 2000 grid sand paint before you run out.)

For advanced shenanigans try to avoid nitro paints too (they are a bit more laborious to keep shiny)

There are... Some... Paints that are more resistant but they are not available to the mere mortal that worries about paying for detailing.
Ferrari has ceramics based clear coat since the F430 that is pretty tough. But you also pay 5 figures just for changing the synchro belt so there's that.

E: the paint isn't really protecting much. The sections of the car that are subject to rock impacts and splash from your own vehicle have a lot more complex layering than just paint on top of primed metal, that's the actual protection. The rest... Eh... Doesn't matter much.

The best rust protection is a flame zinced body but the last ones we made in Germany left the factory at the end of the last century. They really do not rust tho
