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?

I’m by no means an expert here, but as many other have said there are certainly quite a highways and city streets that are concrete instead of asphalt.
From my father that works in construction, it certainly is more expensive, but as others have said it also tends to last longer.
The main issue he’s told me about is that it is also much more technically difficult to lay it correctly. Near me there are several concrete highways, some ride perfectly smooth and comfortable, however the others that I guess weren’t done as well are incredibly uneven and bumpy and have been since they were brand new.
So higher costs as well as the potential to make errors that persist for long periods of time are definitely considerations.
