patio base material

I just had a concrete slab patio removed with plans to put down pavers. I was planning on a 6 inch base of crushed stone mixed with stone dust, with a top 1 inch layer of stone dust to set the pavers in. What I found beneath the concrete pad was sand; at least 15 inches deep. Do I need to remove the sand or is this an acceptable base material?
