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?

The cost of painting an entire road surface would be disproportionate both in terms of the chemicals and materials used as well as the maintenance to keep them white.
