my driveway has lasted 21 years withour retarring. it is the same material as my street. we have 3 cars parked there at all times and many bikes (motorcycles and bycicles) in the driveway all the time. no problems what so ever. it is starting to fall apart a little where i spilled a gas/oil mix for my lawnmower like 6 years ago. pretty good for new england eh?
