Colour aside, there are pros and cons to both.

Concrete is significantly more expensive, to both deploy initially & maintain over time. Sure it lasts longer, but given the significant lack of funding nationwide for infrastructure - if you want roads to be concrete it's going to come from one place - out of the tax payers pocket.

Asphalt is cheaper and quicker to deploy, has a shorter lifespan, but can be recycled (melted down and reused). It also is far more forgiving on vehicles than concrete.

Asphalt has far better traction, and absorption. So in TX, where they aren't dealing with freezing temperatures as often as, MA let's say, it is more feasible to use concrete. It's not as practical to build concrete roads in colder areas that will turn into ice rinks in the winter.

The colour (I believe, but could be wrong) is more to do with the aggregate they can source locally versus for any aesthetic purposes. Want purple roads? Well that'll prob cost even more for w.e chemical they use to dye it, and who's footing that bill - you got it, the taxpayer.

Asphalt, while not ideal, is far more practical for most applications.

What we really need, is a new material/solution that has the durability of concrete, but cost efficiency & recyclable nature of asphalt.

Colour for aesthetic purposes is pretty low down the list of actually important factors

Edit: I think it's "brighter" in Florida because it's sun bleached.
