Persistent pothole - need more than tractor tools?

[Egon]

On a grade the transition section will probably require about the same amount of maintenance as you currently have.

Either resurface the hole road or keep the patch as small as possible. We live in the sand hills and our county road has a lot of heavy truck traffic on it which causes a lot of pot holes to develop. The county has used what ever they had handy at the time, asphalt chips, crushed concert, gravel, ab3 rock with fines to fill the holes. It all works great for awhile but, with the original road being softer than the patch material, as the road is graded and rain washes down, the original road material is pealed away from around the patches creating new pot holes and a very bumpy road.

Get some 3/4" crushed rock and fill the hole but leave it a couple inches below the top and drive over it to pack it in. The jagged edges of the rock really lock the rock in place. Then blade the road over the hole to cover the rock. That way you only have a small area to have to mess with if it keeps coming back.

Not sure where to post, but since I've been using my backblade, boxblake and rake + tractor to solve this, I'll start here. I have a very steep gravel drive with a 90 degree turn 1/3 of the way up. Just before the turn and on the inside (a right hand turn) I have a persistent pothole. Drivers slow, stay to the inside, then gun the engine and spin their tires. I've gotten good at using the boxblade to fill the hole, but it is back after only a few visits from delivery trucks and/or guests.

Is there some type of "binder" I might apply in that section of the drive? I've had a bunch of "fines" dumped there and that worked until I had a ditch overflow and wash them down the hill.

Other suggestions? Or is this a situation where I just need to enjoy the seat time?
Thanks,

As mentioned, you need coarses and fines. Rake all loose material out of the hole and refill with a mixture of gravel and fines that will pack. Dampen it, tamp and drive on it til it becomes almost impervious to water. Make sure it is not the low spot so water wont collect. You will have to control traffic for a few wet/dry packing cycles so it has a chance to stabilize. It has to become well consolidated and with no loose surface material to cause a spin by the uncoordinated. A carefully worded sign and prompt attention to any damage should the keep it healthy.

It sounds like I'm going to need to "treat" the curve rather than just the pothole or just enjoy the seat time. I tried searching for a source of asphalt grindings but don't see a local (central Indiana) source. I had thought about pouring a concrete section, but have been concerned if I can maintain a smooth transition to the gravel on either side.

I am (hopefully) about a year out from retirement. Maybe I'll just keep using the backblade until then. Sounds like a bigger project than I want to take on right now.

Thanks for all the advice,

Not sure if they will let you take any but they have a couple of huge piles over on Hwy 45 between Hwy 54 and Hyw58. They are resurfacing the road there and in the middle is a holding place for materials. With all the rain we've had this spring, everything is spongy.
