Default Re: rock removal ideas?

We built a horse riding ring last year and had a 10" layer of compacted screenings (Crushed stone dust) put over the compacted subsoil. This was followed by the sand layer for riding. The compacted stone is used specifically to prevent upward migration of rocks from the subsoil layer in to the riding surface. It is extremely effective but very costly. I think without something between the dirt and sand you will always have rocks migrating to the surface especially after a freeze thaw cycle. It takes alot of screenings to do this and some ring contractors use only a 6" layer. Our ring (80' x180') took 28 triaxle dump truck loads of stone to achieve a 10" layer. Just my two cents, but that is how rings are constructed in southeastern PA.
