Why is black asphalt the default material for surfacing streets, especially in hot climates?

The title is the question.

Maybe it’s the cheapest thing with the right properties, but can’t it be painted with something a little more reflective, that won’t absorbe so much heat from the sun?

It’s cheap and fast. I’ve seen miles of asphalt paved in a single (long)shift. I’ve never seen more than a few hundred feet of concrete pavement done in a day. Interstates use concrete with an asphalt pavement overlay to get the durability of concrete, but the traction and repairability of asphalt pavement.
