Yep, it's done on purpose.

most of the highways around houston are rebar concrete. sometimes asphalt will be poured on top to extend the life. most of the side streets are concrete as well (with heavily trafficked streets getting a layer of asphalt).

asphalt sucks ass. it doesn't stay where you put it. it buckles under weight. it's hard to repair properly.

It is nice to get a top layer of asphalt, just because it's quieter and gives you more traction if done right.

Well it be fair the roads do get the fvck pounded out of them by all the trucks, constant traffic, winters, and de-icing chemicals up here.

Our roads are built poorly. I don't know why they do this, but here's the scoop. American roads are built to last for a short term. Roads in Europe are designed to last twice as long. The ratio is 2 to 1. Roads here rebuilt every 10 years, in Europe, every 20 years.

probably due to the fact that there are a vast deal more highways in the US.

Yea here in NC they use a lot of concrete for highways now and some other roads. They are really bad. All the gaps for expansion just mean as you drive it moves the car up and down and of course you get the whole tump...tump...tump... sound as you drive on it. :|

The roads are built differently. I remember reading this somewhere. Ours are more disposable while theirs last longer.

If commonly used roads were reinforced with rebar, would we not have to resurface the roads as much? Would it save us money in the long run to just reinforce commonly traversed roads with rebar due to the lessening of resurfacing?

All concrete roads are rebar reinforced.
Rebar reinforcement only strengthens the base to prevent raising or sinking.
It does not solve the surface freeze thaw cycle which cracks the surface and eventually causes potholes... this is where asphault resurfacing comes in.

which is 9999999X more expensive than rebar and 999999999999999999X more expensive than laying asphalt every 5 months
 
Roads are such a waste of space. To add capacity they just widen the road. Now if they could figure out a way to stack roads on top of another it may be possible to reduce jams. Cars will probably fly before then. 🙂
