Concrete cracks. Seriously. Expansion joints are there to create "controlled" cracks. Asphalt roads are more "flexible" and do not need expansion joints. Concrete roads last longer than pure Asphalt roads.

The expansion joints are supposed to have a filler in them, but usually over time, these disintegrate. They are especially dangerous for road cyclists. We call them,"The valley of death".

I've always said that the best roads are concrete, covered in thin layer of asphalt. No expansion joints, lower noise, etc.

They do make a machine that is used to "level" the different pieces of concrete. It is basically a grinder.
