This is a great thread topic. I've been debating the same question. I prefer the look of concrete much more than asphalt but the cost is much higher. Another consideration (for me, not sure about others) is that the ground moves quite a bit where I am at and some concrete driveways on my street are all cracked up, from ground movement vs the asphalt that will not crack when the ground moves. With that said, not all of the concrete driveways on the street are cracked, so I imagine alot of it has to do with prep work and proper reinforement in the concrete. I am still undecided, but enjoy reading others opinions and thoughts on the subject. I will probably go concrete as I will like it much more in the long run.
