Pave directly on "water-based road surface"?

Hi,
thanks for your answers, which have helped me a lot. The path surface was compacted several times back then with a kind of "gravel" (0-8mm grain size). Only some small stones come loose over time/load/weather conditions.

In summary, I can now proceed as follows:
1. Loosen the path surface/top layer and remove the necessary centimeters
I would probably do this with a hoe/rake because it is only an area of 10x3.50 m. I already tried earlier, and everything loosens very well and quickly with a pickaxe.
2. Then set concrete edging stones in earth-moist concrete and align them to final height with a rubber mallet.
3. Put about 5 cm of gravel (2-5mm) between the concrete edging stones, paying attention to the slope, and then compact once with a vibrating plate.
4. Then simply place the paving stones on the compacted surface on the gravel.
5. Brush fine gravel into the joints.

Is that correct?
Do I have to compact again after brushing in the fine gravel or even wait some time before a car can park on it?
And is "simple" garden post concrete, on which you pour water from a watering can and then work with, sufficient for the concrete edging stones?

At 1, scrape off and shake
at 3, insert split, scrape off with slope and height
at 4, lay the pavement
at 5, shake the pavement with a rubber plate,
at 6, wash in and sweep,
Afterwards you can drive on immediately

@ : Thank you again for the answer. The very last final question, so that I can be sure I have understood it correctly: I tamp twice, once after I have removed at 1., then the gravel AND the tape go on top, and then I tamp the second time. As a result, I do not tamp on the removed gravel. Thanks in advance and have a nice Sunday!!

Exactly, the gravel is only compacted with the paver.
