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?

San Antonio TX is implementing this actually! They started with a pilot program where they tested multiple road materials and coatings. It is now rolling out to the city at large. It’s supposed to cool the area by 20 degrees farenheit.
