Hi mwayne and airbiscuit. Thank you for the Andrew Camarata info. I just watched the youtube link airbiscuit added and he makes it look so easy, so I have hope. Our driveway used to be EXTREMELY bad and the gravel would wash down the driveway leaving long ruts (hubby was pissed every time it rained hard and he saw all the gravel rushing down the drive). Because we're using surge stone, there is no gravel run off, but now there are numerous potholes.
The uneven driveway is not good for my car either. Last week, I was hearing an occasional thumping noise when I drove and when I took it to the Honda dealer, they found a 3" x 3" rock by my control arm and told me that my skid plate had numerous dings on it.
I have added a picture of my car and you can see that it's about a 20'ish degree slope (looked up the difference between slope and grade).
A 3x3in stone is nearly rip rap stone. Either way 3in stone is not a top surface that you should be driving on. 3in is good for a base then you need to top it and crown it with a finer stone. Item 4 is a nice stone mix to top a driveway with.
