Ricn, I think I get exactly what you mean. It looks like many of these responses really don't. I have your problem with our steepest hill (mostly straight up), particularly with my FIL who tends to slow way down halfway up the hill in his 2wd PU truck, then hits the accelerator, which invariably leaves big "spin holes". In my case, it is excacerbated in that the road base in the middle of the hill is solid shaley rock a few inches below a top coat of gravel. Regardless if it is "57s" or crusher run, the same thing happens. It is definitely better with a thin coat of crusher run, wetted down and packed as much as possible. The 57s with no fines may just as well be marbles. We once even tried a substantial coat of mortar mix on top to try to solidify it or at least make large and hard to move "sheets" that would key against the base. It just crumbled.
Unfortunately, nothing is really successful for long.
The best I have been able to do is to grade it with a LPGS, leaving as thin as practical a coat of crusher run.
I suppose that tar and chip may work if it were glued down to the base rock with enough tar, but that is outside the budget.
