I have done this several times with just a tractor, but I have never gotten any videos of it.
The only thing I might add is a plow, just because it really helps loosen the soil, and doubles as a counterweight, but it is not really needed if you do not have one, or can borrow one.
For me, I staked out the width of my road, every one hundred feet, and then figured out the width of the ditches, and thus plowed the ditch areas on both sides of my proposed road. Then I used my front end loader, working sideways to the road, and scooped up the loosened soil, and dumped it where my road was going. I had to do this twice, as I wanted some deep ditches, and needed more soil in my road as sub-base. Then I graded off the dirt I had dumped into the road with my front end loader, and then used my grader (you would use your box blade) to smooth the sub-base material.
Doing this did two things. It helped for nice ditches on either side, but also built up my road by 18 inches or so. This allows water to drain out of the road, and in a road, drainage is everything.
I have my own gravel pit, so I hauled my own gravel. I used a 1 cubic yard dump trailer that I have. My wife drove her Ford Explorer, pulling the trailer, while I loaded it with my Kubota in the gravel pit. (I could have used the tractor to haul the trailer if I wanted to unhook, load the trailer with the Front end loader, and then hook up again to haul it). To help loosen the gravel prior to digging it out, I used the plow to loosen the soil. It took 350 cubic yards of gravel to surface the road, but by doing (10) trips per day, we had the task done in just over a month. (Some days we hauled more loads, and some days we hauled less).
But of course, you could always buy gravel by the truckload and spread it yourself if you do not have a gravel pit.
My road is on a 9% grade, so I had some additional things to do, like build a few rock check dams for erosion control, and put in four water bars to divert water off the roadway. I also call it a road because it was designed as a "heavy haul road" as the government calls it, and thus is designed for big rigs. logging trucks and lowbeds in my case. Yet I built it all with just my 25 Hp tractor, a dump trailer, a plow, and grader.
Since then, I also built a new driveway to a house I am fixing up, using the exact same techniques, but that was a much smaller project compared to the roadway.
Here is the muddy mess I started with, and then the roadway after it was done, all done with a 25 hp tractor and some implements,. Despite heavy truck traffic, it still has help up well even after three years, and is a true 4 season road.
