I grew up in an area with these kinds of roads and I don't think they're technically compacted. The gravel, which is crushed limerstone, is laid down and due to its chemical properties creates a smooth surface after several months of traffic.
I've used surface=gravel; gravel=crushed_limestone in my area. I don't get the gravel being 4-8 cm, that seems a wikierror.
