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 is much cheaper than the other popular type of pavement, reinforced concrete. A road surface that reflects a lot of light could be blinding to drivers but the same thing could be done with roofs
