Relationship of void ration to rock size/shap - Soil ...

You could specify the voids and let the contractor select the stone. Or you could specify 1.5" to 3" clean stone, as others have suggestes, but the actual voids will be subject to variation depending on the exact shape of the rock. You would have to test the actual stone to be sure. BTW, this is a common problem.
