Pave directly on "water-based road surface"?

Good day,

a year ago we had a bound gravel surface (grain size 0-5mm) installed as a driveway. Beneath it is a frost protection layer (gravel/Proctor). Everything was compacted several times with a vibrating plate. I have attached several photos of this.

Unfortunately, we are not completely satisfied because small stone particles keep coming loose/the shoes get dirty when wet. For this reason, I wanted to ask whether it is theoretically possible to lay paving stones on this compacted surface. The frost protection and gravel layers are already there, right? It should work if you set curbstones in concrete on the left and right and then fill the paving stones in the middle with joint sand, correct?
I am grateful for any helpful answers :)

Hello and thank you 11ant. You are right, it is thematically related. But the specific question of whether I can pave directly onto the existing path surface or if preparations need to be made was not described. Perhaps as a layperson I just couldn’t discern it. Best regards

if all the plan is screeded, set edges in damp concrete, put in gravel, screed and lay 6cm paving (footpath, car) or 8cm paving (footpath, car, tradesman van, motorhome), compact with rubber plate, wash in fine gravel and sweep. Pay attention to the slope, so that during heavy rain neither your own basement nor your neighbor's gets flooded

Specifically for laypersons: The water-bound surface does not replace the gravel under paving. You need to apply more here.

And then take the greater installation height into account. Compared to the old version, you need 10-12cm more. Around [Schachtdeckel], at the street, etc., this can lead to problems.
