ᐅ Can you pave directly on a "waterbound gravel surface"?

Hello,

A year ago, we had a crushed stone driveway (grain size 0-5mm) installed for our car entrance. Below this layer, there is a frost protection layer (gravel/Proctor). Everything was compacted several times using a plate compactor. I have attached several photos of this.

Unfortunately, we are not completely satisfied because small stone particles keep coming loose, and shoes get dirty when it is wet. For this reason, I wanted to ask if it is theoretically possible to lay paving stones on this compacted surface. The frost protection and gravel layers are already in place, right? So it should work if you set curbstones in concrete on both sides and then fill the joints between the paving stones with jointing sand, correct?
I would appreciate any helpful responses 🙂

Hello and thank you, 11ant. You are right; it is thematically related. However, the specific question of whether I can lay paving directly onto the existing path surface or if I need to make preparations was not addressed. As a layperson, I may simply have missed it. Best regards

Once the entire area is leveled, set edges in damp concrete, add gravel, level it again, and lay 6cm (2.4 inches) pavers for footpaths and cars or 8cm (3.1 inches) pavers for footpaths, cars, vans, or motorhomes. Compact with a rubber plate vibrator, then brush in fine gravel and sweep it off. Make sure to consider the slope to prevent your own basement or your neighbor's from flooding during heavy rain.

Specifically for laypersons:
The water-bound surface does not replace the gravel base under paving.
You still need to add more of that material.

And keep in mind the increased installation height. Compared to the old version, you’ll need 10–12cm (4–5 inches) more. This can cause issues with manhole covers, streets, and similar areas.
