A neighbor INSISTED on a gravel drive to save on property taxes.

so he dug down a couple feet, installed a thin asphal;t drive then
covered it with a foot of gravel.

only driveway with zero mud or weeds.......

I think the OP should get the original contractor or similiar to return
add more tar and a new layer of stone to freshen it up.

gravel driveways arent maintence free.
