Any driving surface installed requires maintenance. If you install concrete streets once the useful life is exhausted you put an asphalt overlay on them. This adds oil to the concrete to keep it flexible thus preventing cracking and pot holes. If you install asphalt streets you still have to do seal coats to add oil to the asphalt to keep it flexible.
The kind of seal coat or overlay that can be used depends upon the type of surface installed. Once the seal coat is applied the street is nice and black. Once the street has turned grey or the old striping is visible the seal coat is gone. Meaning your driving on the original dried out surface. Since the surface is lacking oil it cannot move with the ground when it shifts causing cracks. Couple that with the weight of trash trucks, delivery trucks, moving trucks, other heavy vehicles, along with passenger vehicles grinding away the rocks in the asphalt causing them to come loose and you get pot holes.
Don't let your streets get dry and crumble when it can be avoided with a simple seal coat.
