I get 20 tons of #1 stone about every 5 years and it looks good. Blacktop is not maintenance free.
Wish I could get by with that, it takes 50 ton to do mine right.
There are many things to consider on whether or not to pave a driveway. Assuming there isn't extreme heat that would make the asphalt soft, it can be made to withstand truck traffic. It would need a better base than driveways typically get. Concrete is tougher than asphalt but the snow will melt off of asphalt quicker. A paved driveway is cleaner than a gravel driveway.
I wouldn't pave my driveway for 2 reasons; the high cost and it would scare me to try and go down a mountain driveway in icy conditions. The gravel gives me more grip.
