Just looking for some advice from the "been there, done that" people. Heres the story.

I have some work lined up to spread crushed shells for a driveway. I've done this with decent success just motoring along and slowing curling the bucket down to dump them, then drag out to somewhat level.

The problem is that after only a few months, ripples form across the driveway along with massive potholes. /forums/images/graemlins/frown.gif (The real problem is that the driveway is probably 1/4 mile long and they drive too fast down it /forums/images/graemlins/crazy.gif )

My thought is to try and crown it. (Second thought is drainage, but I think the crown is more of an issue).

Heres the questions:
1) Do I try to rip up the base with BB ripppers (can it, even?) and crown that before spreading the new stuff, or leave it and crown only with what is delivered? The current drive has some shells on top, with mostly gravel underneath that may have shells and some 3/4" stone mixed in.

2) Is it worth it to try and crown with a BB, or should I just look into borrowing a back blade to save myself the frustration?
3) Grass runs along the side of the driveway, and I think that it might foul up drainage. Should I just make a shallow ditch for runoff alongside?

I guess thats it. Any advice/critiques would be appreciated. I am up for "experimenting" in a few spots - it all doesnt have to be perfect on the first try.

Thanks

If you are getting ripples and potholes then your driveway base isn't holding up. Maybe a thicker cover or something stronger underneath. Around our weekend place you get the red clay with the little pieces of iron ore (what we call it). After it gets packed down and the rocks come up it'll last a long while. The rain doesn;t get through it after it becomes packed. Hard as a rock in a rain storm.

Good Luck

You are lucky to have ripples and pot holes that need repair. Offers more opportunity for seat time. /forums/images/graemlins/grin.gif All kidding aside, that's why I'm not going to gravel or asphalt my road. I bought the tractor instead of paying for road topping.

As far as your questions, crowning a road will help with rutting or ripples somewhat. I found it more important to do where the road rises and falls moreso than on completely flat sections of the road. The run-off has a greater chance to build up velocity on those inclined sections and do more damage.

A backblade is probably the better implement for best grading results. On the other hand, a boxblade will also do the job. Not having a backblade, I use my boxblade for all road maintenance and repairs and even to cut "gutters" along side as you were inquiring about. It has worked out well and have no need to spend money on a backblade now. In this photo you can clearly see the grading work and also the gutters.

RobJ- What is the best way to solve this type of problem? This is a lengthy driveway, so putting down a lot of material= $$$

3RRL- What you say makes sense. However, most of the driveway is level. I think standing water is more of an issue, though I am not really sure what happens when it rains. BTW, nice work with your BB. I am going to try and tweak mine (equipment & skill) to hopefully get some better results. I'm pretty bad at it right now, but I've got some ideas.

Thanks

Josh,
If that's the case, standing water, I would blade the sides of your drive and cut in a gutter. With the shell and gravel there, work some of it to the center creating a slight crown. You'll most likely drive on that anyway. Try that before buying additional material. Here is anoter photo of a level part of my road after boxblading. Notice the water on the sides in the gutter area.

Set your boxblade like this to cut the gutters. Make several passes on each side if you need to. If using the boxblade to do this, try not to use the scarifier down on that low side. It is a real easy way to bend them because the boxblade is not square to the tractor's direction of pull now. The low end actually sits a bit farther back than the high end and the scarifier is now slightly angled. I used mine to cut the gutter first and bent the heck out of each one I put in until learning the hard way.

I've been working a fairly long curving hillside driveway for a while. The crushed limestone 57s that were delivered were laid in too thick. The folks living there drive F350 superduty trucks. They come up the drive in 2 wheel drive and very quickly make a bunch of small waves in each tire track.

I've moved quite a lot of the gravel further up the hill, but there are a lot of places where it's still too thick. I spend a fair amount of time with the back blade and bucket working the thing over. Even with the blade angled, tilted, and offset outside the wheel, each pass tends to move a little gravel further out, widening the driveway just a bit. It seems like a box blade would keep the stuff in the driveway better, but maybe I'm wrong on that count. I don't own one, and don't need to spend the $400 or so to get one. Any ideas??

From my experience with the boxblade, that is correct. Even with the lower end slightly trailing the high end, it still grabs the material and displaces it away from the gutter (towards the center of the drive). I have no experience with the back blade so I can't say anything about that. But the boxblade has sides and keeps stuff from spilling back into the gutter, or widening the drive. Then I reset the angle ... not nearly as steep and grade the spillage and the rest of the road to put a light crown on it. Comes out looking pretty good and the gutters sure work.

Another super handy feature is the ability to back up, bulldozing the gutter into natural spillways...on the same angle as the gutter. On my property this was very important so the gutters didn't overflow before the water flow could reach the culverts. In bulldozing, you can set the back cutting blade aggressively and cut very nice escapes. It also pushes and levels the dirt so it makes a nice path for the tractor, never worrying about "going over" the edge. (Note: stop first). The Top-n-Tilt toplink has been a tremendous aid in positioning the boxblade for cutting or smoothing in forward or reverse..."on the fly".

I do this on more inclined parts of the road rather than the flatter parts. It is more important to do that where the water gains/accelerates and will rut and wash out your road. Another reason I like bulldozing backwards is that your tires end up on the area that has been bulldozed away so it will be nice and flat...not bumpy. Not like pulling the boxblade where it tends to ride up and down with the tractor if your tires are going over bumps. Bulldozing cuts those bumps out and you have immediate flat results.

I think this photo shows what I'm trying to explain about the spill-off areas. Notice how the slope follows the gutter slope, and the road is left up higher and smooth.

For those of you who saw my post on customizing my boxblade with added re-inforcement, weight, and hydraulic rippers, now you know why I invested so much time in it. Of the 180 or hours I have on the tractor, about 100 hrs have been working the boxblade, 50hrs with the backhoe and the rest trying to figure out how to work the tractor. /forums/images/graemlins/confused.gif

3RRL: (Edit: whoops, addressed wrong person before)
Do you think I could set just one or two scarifers down with the box level and bust up the soil before trying to dig a gutter?

If not then I guess I can just rip half on the drive and half on the dirt. Still not sure if I want to rip the drive up or not, but I guess that would flatten out the hardened bumps and give me a fresh start. I appreciate all your advice on this, thank again.
