As a general statement, a pot hole type failure in any finish
surface indicates that moisture has increased the plastic index
of the subsoil beyond its acceptable limits, and/or the loads
imposed on the surface are too large. In other words, the garbage
truck is too heavy or driving through the wet pot hole has driven
the moisture too deep into the soil.

You can try adding a fresh layer of crusher run or chat over the
damaged area. If this is a pot hole that keeps coming back in the
same place year after year you will do better to dig up the bad
spot to remove the saturated subsoil and refill with geotextile
and course stone and then top off with finer material. You will
need to do something to eliminate the moisture such as crowning
the drive, increasing the "barrow ditches" on the sides, or
creating subsurface drainage.

Each area has different terms for local stone and granular fill.
I do not recognize "driveway mix". You may not recognize my
"crusher run" or "screenings". Work with your local supplier and
explain your problem, they will fix you up with the local
equivalent.

I've got a giant pothole in my crushed stone driveway. It's
about 3 feet wide by 10 feet long by about 8" deep. I've heard
of stuff called "driveway mix", but I haven't a clue what's in
it.

So, do I just get a yard of crushed stone and dump it in there?
Or do I need to get some of this "driveway mix" and use that?
Or do I need to excavate and install perf pipe or what?
