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 🙂

thanks for your replies, they helped me a lot. The pathway surface was compacted several times back then using a kind of gravel (0-8mm (0-0.3 inches) grain size). Only some small stones tend to come loose over time/load/weather conditions.
To summarize, I can proceed like this:
1. Loosen the pathway surface/top layer and remove the necessary centimeters (centimeters). I would probably use a hoe/rake because the area is only about 10 x 3.50 meters (10 x 11.5 feet). I already tried earlier, and with a pickaxe everything loosens very quickly and easily.
2. Then set concrete curbstones in earth-moist concrete and align them to final height with a rubber mallet.
3. Fill about 5cm (2 inches) of gravel (2-5mm (0.08-0.2 inches)) between the concrete curbstones, making sure to maintain the correct slope, then compact with a plate compactor.
4. Place the paving stones on the compacted gravel surface.
5. Brush in fine gravel into the joints.
Is this correct?
Do I need to compact again after brushing in the fine gravel or wait some time before a car can park on it?
And is the simple garden post concrete, which you just mix with water from a watering can, sufficient for the concrete curbstones?

Thanks again for the reply. Just one final question to make sure I understand correctly: I compact twice, once after I have removed 1., then gravel AND pavers are placed on top, and only then do I compact a second time. So, in the end, I’m not compacting on the removed gravel.
Thanks in advance and have a nice Sunday!!
