Whoops!

Well, while the driveway looked good when I finished it. It now sucks! Bumpy as crap. This blade will take sometime to get used to using. I might ask my neighbor to help me with the learning curve and make sure I have it set up right.

He normally grades the driveway, or at least the lower section and his. But now that I have my own, I want to learn.

Taking out the large rocks seems to actually hurt the driveway. But with time I'm hoping I can fill the holes and smooth out where the rocks were. I literally pulled out 30-40 head size or larger rocks out of the driveway.

One scraper blade trick I learned from a farmer buddy is to reverse the blade when trying to get an even spread of gravel, crusher run, etc. Having the face of the blade angled back instead of forward allows it to float instead of digging divots out as you go. If you haven't tried that, it may help you get your material better dispersed. Box blade does that kind of work better, but you can do a decent job with the scraper blade with some practice. Nice and slow works better than hurry-up quick. Also, big chunky rocks and debris interferes with the leveling process. Do as much as you can to get that kind of material out. Keep practicing... it's an acquired skill!

If the rain holds off I will try that today.

Well, here's an update for the driveway.

I broke down and got a Box Blade, 5'. Took well over 30-40 passes to get all the large rocks pulled out of the driveway, even broke the tip off of one of the tines. Just the corner of one tine, so not to worries about it.

After pulling as many large rocks as I could I rolled the top link back and pulled tines up one hole and then started to move material with it. Smoothed out really nicely! Was rather surprised!

BUT! Now after last nights rain, the driveway is super soft! Like my boot and dogs paws sink in about 1/2" and even 1-2" in some areas.

This is what I am thinking and maybe you all good fellas can point me in the right direction. I just ordered 10 tons of 2-3" gravel. Plan to make a lower spot on the right side of driveway and then make some channels about 4' wide across driveway and fill with the large rocks. Then once money permits bring in some more 2-3" stone to fill the whole driveway. Drive on that for 6 months or so and get 3/4" with fine and cover all the large stones except the side that I made the low spot for drainage.

What say you?

Curious about the large rocks, were these sticking up when you started the project? Could you have covered over these rocks and left them alone?

About the soft drive after the rain. I would not expect it to be firm without rolling and packing and would rather try to firm it up before putting the 2 to 3 inch rock on it. This larger 2 and 3 inch rock could be a pain to deal with later on coming up through the finished driveway. I suspect a thicker layer of base course 3/4 to fines packed down would work better. Get this base crowned and shaped to allow quick run off and get it smooth. Then add 3/4 clean rock on top of that about "one rock high".

I should add that drainage of the water would be the first goal and any culverts or other diversions for run off should be done first. When you are sure this works correctly then build up the base with a crown and compact it.

The main issue was water run off and washing my smaller stone away. The shape of the driveway makes it hard to crown, it needs to be sloped to one side or the other with a drainage area next to driveway. Only way I know to do this was to break all the large rocks out of the driveway, which was making the driveway really rough. The little rock wash down drive and large rocks exposed, grading little rock back to the top was a pain and didn't work very well. Watched the neighbor try before I got my tractor.

With little rocks removed and now bringing in larger stone as a base. I want to build a thicker large stone base and then compact with driving on it for a few months. Once I feel it is nicely compacted then I will put a 6" 3/4 w/fine base on it and compact with a roller of some sort. All the while keeping the slope of the driveway heading towards the creek where the water wants to go to anyways.

You can crown the driveway with a center high point or a side high point depending on your needs. As long as you can keep the water from running in the driveway and get it to divert around it you should be good. You could use the larger rock (2 to 3) as long as you are willing to add a thick enough layer of the 3/4 to fines over it. Most people can't seem to spend the money for enough gravel to do this. Just make sure you don't rip to deep and bring up the larger stones in subsequent years grading the driveway.

12bravo, I've been trying to follow along on your efforts . . . but a few definitions would be helpful.

1. The large rocks you are taking out - how big are they? Are they 6 inch or bowling ball sized or flat step rock sized. I've seen the words larger rock used to apply to the road. but 2 - 3" is normally what all driveways use as "base rock". Then you use "3/4 minus" rock as finishing over the base rock.

2. Where is the water pressure direction? Does it follow the driveway or does the water run at the driveway? Does it funnel to specific points or does it pressure all along the driveway? Normally if the water pressure runs with the driveway - you try to "case harden" the pressure side to prevent erosion pulling the material down along the driveway. "Hardening the edge" with base and then pressure build with 3/4 minus on that same edge keeps erosion down and keeps water from crossing. If the water pressure is "at the road" - normally you try to make "crossing" or "pressure reduction" bridges of base rock plus a quality compost. This allows water to transfer across the driveway in pressured areas while the base rock and compost combine like a control dam. Then 3/4 minus is used as a hard topping where these are done. In addition some slotted drain tile put in that same crossing area helps transfer heavier water rains etc. from one side of the driveway to the other at those key points.

3. The idea of base base rock on top of a really soft road bed/driveway bed is good if you can drive those 2" to 3" rocks down down down - in effect trying to create a weaker version of starting the driveway with base rock before anything else. TN has freezing and gravel is notorious for going soft when thawed and pushing big rock to the surface. So if you are trying to "harden" the road - compacting base rock into soft driveways can help . . . . but the real key is understanding the direction of your water pressure and creating those relief needs. Think of it like your hydraulic lines on the tractor - without a relief valve process- pressure could build anywhere and it would be bad for hydraulic lines. Water creates hydraulic pressure to be relieved. As an example - lots of tight gravel creates dam - and with no leaching or relief - either the dam holds under pressure or it blows out anywhere it can. In sandy soil - good quality compost allows the soil to hold together better - and in heavy soils - good quality compost allows water transfer without erosion. We used the principle on our heavy clay soils in our steep pitched slopes that bottleneck flowed water - as we were building.

I have some experience with this also. I ripped out my "landing area" in front of the garage to stop water going under the garage door. Then put it all back about a 1-2" lower.
Used the bb and advice from here and it looked AWESOME MAGNIFICENT!

Then we got 2" rain in one day. I went to town and upon return home, stepped outta the truck and was in driveway to my ankles!

It's gonna have to be compacted. I read somewhere but I'm sure better advice will come from the guys here to compact it after every 3-4" raise with loose fill/gravel before adding more and then compact the top layer as the final step.
I ain't no expert but I read this all on the Internet! So it's gotta be true.
