GOOD & BAD SUBGRADE

[dirtworksequip]

Obed, here are some pis of a road currently under constuction. Pic #1 is of a properly graded subgrade. That is pitched to drain. Although not done yet. I wanted to give you an idea of what it should look like when almost done. When finished it should not have any tire or tread marks. And should be hard enough to not leave any tread marks when driving over it. If it does you need to work on it some more.

Pic#2 shows a grade that is not ready for stone. Notice the small water holes. These holes will cause problems later if you stone it before they are graded out.

Again I cannot stress enough how important it is to spend a lot of time on grading the subgrade properly. If you skimp here you will pay for it later. Either in needing additional stone or grading out the potholes. So do it right from the beginning.

One other thing. When it drys out if there are any wet spots you need to determine where and why its wet. If needed, a french drain should be constructed to dry up any wet spots if its ground water.see pic #3 There is water bleading out of the bank. It will need to be corrected to dry it up before I can stone the road.

With as much rain as we've had here, you'd be hard pressed to find a DRY spot. I've got water bleeding out of spots where it never was before...so much for the mild winter predicted.

I have always liked the "proof rolling" method. If the ground shows any deflection under construction equipment it probably isn't up to suitable compaction.

dirtworksequip,
Thank you so much for the help. I'm sure getting an education. Now I'm playing the waiting game until it gets dry enough that I can pack down my road. CUT Box Blade Newbie - Road Pictures With all the help I'm getting from TBN folks, I'm optimistic that I'll have a great road at some point.
