Some countries, including Russia, and Poland DO use roadways as runways. However, if you look at Russian equipment vs American equipment, the Russian
aircraft are designed to be flown off unimproved airstrips. The MiG-29 and YAK-130 are prime examples of this.
Here is the MiG-29 on the taxiway:
Notice the intake doors? Those allow air to get in to the engine, while keeping what's known as FOD (rocks, nuts, bolts, things that make jet
engines very unhappy) from going down the engine intake, and destroying the engine.
Now by comparison, here is the F-15 and F-16 that the US uses:
On the F-15, the intake drops down to an angle like that for airflow purposes at low power settings, but it doesn't do anything to protect the
engine. The F-16 on the other hand, having the intake on the bottom of the aircraft like it is, is a vacuum cleaner when the engine is running. We
used to joke that there was no need to have them sweep the ramp around the F-16s when they were in, because they'd take care of it for us.
When you add in the sheer size of the aircraft that the US uses, there is no physical way possible for the Air Force to use any roadway as a runway.
They simply aren't stressed for that purpose. If you've ever driven down some of the highways (I-10, I-12 especially), riding in the right lane,
you've felt how rough the road is. That's from trucks grossing out at 80,000 pounds. Now imagine if they tried to land something with a max take
off weight of hundreds of thousands of pounds on that same road?
