Hello everyone,
I have a rear plot where we moved in July. Our driveway (which belongs to the property) from the street at the front is 4.5 m wide (15 feet), and after about 30 m (98 feet) the actual plot begins. The driveway was compacted with recycled concrete base material during the construction phase for the construction machines and a crane.
I recently had a walkway installed on the right side of the driveway with 6 cm (2.5 inches) curbstones on each side and paving stones in the middle.
Now, on the left side of the driveway, I want to install a row of curbstones as well. Between these curbstones and the inner curbstones of the walkway, there would then be a roughly 3.2 m (10.5 feet) wide driveway lane for the car.
There is still about 40 cm (16 inches) of vertical space up to the top edge of the curbstones. Since I have a lot of topsoil left from the excavation, I was thinking of spreading it over the driveway lane and then adding a layer of recycled concrete base material on top, followed by compaction.
That should work, right? Because under the topsoil, it is already compacted, and on the left and right sides of the driveway are the curbstones set in concrete. So despite the topsoil, the ground or the future grid pavers should not settle.
What do you think? Can I safely get rid of some excess topsoil here?
Regards

I expect wheel ruts to appear very quickly.Although below the, let’s say, 20cm (8 inches) topsoil layer, the compacted RC material is already present? I would also compact the topsoil as much as possible using a plate compactor, and then place another 10cm (4 inches) of RC material on top, which would be compacted again.
Would the topsoil still pose a risk of settling?

There will be rutting.
I also expect drainage problems in the topsoil layer.
In short: I wouldn't do it.
