> I can't recall ever seeing a runway shutdown abd inoperable for months on end due to "road work". I’m guessing you haven’t flown through Phoenix recently? They have had a runway closed for repaving (might be reopened now) since early January. Runways are generally concrete rather than asphalt and there are plenty of concrete highways. It tends to be a louder and less comfortable surface to drive on and when repairs do need to happen, they’re more disruptive than a simple asphalt resurfacing. I’m sure there are other reasons to prefer asphalt, but I’m not a civil engineer.
