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?

Alternatives have been tried but almost always end up being too costly to be considered widely applicable. Look up solar roadways. They launched in 2006 and didn’t get their first road equipped until 2016. It’s a good idea but who’s gonna fund it?
