John, there's a mix of concrete and asphalt here out west. There's also some roadways that have been paved with an asphalt that contains rubber in it, resulting in a super-quiet ride in your car. It's quite nice.
Our roads are mostly asphalt. On the interstates, like the NYS Thruway, the surfaces are asphalt over a 60+ year old concrete surface.
The roads are patched often and resurfaced every few years. Quality of the resurfacing depends on how much the road gets used. The resurfacing is done on top of what ever is there. They have resurfaced the road in front of my house so much that the town had to build up the end of my driveway to match the increased height several times in the 34 years I've lived there. I've had to raise the mailbox height a few times too.
I've even seen where pot holes have gone deep enough to show the paved over train tracks (trains ran through downtown Syracuse many years ago). The solution? Patch it and throw some more asphalt on it come spring.
Radials really make a huge difference here.
