Sorry I didn't include more details.
I was thinking #2 stone, 4 inches thick. Maybe it would be smarter to do what you did...in two layers.
There is no existing road. This will be put down from the back of my workshop to an entrance to my back pasture. There is just grass there now.
It is solid clay and will run right by my pond. You can't drive in that area after it rains because you will sink and get stuck...hence why I am installing the road.
