Compaction testing of #57 stone with a nuclear gauge or other device is not possible, even though many specifications state that it should be compacted to 95% of Proctor values. So rather than compaction tests, #57 stone should have it’s individual stone facets properly oriented using a plate compactor, jumping jack, or other

A comprehensive series of drained triaxial compression tests were performed on crushed concrete aggregate (CCA) moist as compacted. When compared to ordinary natural well-graded gravelly soils, the peak strength and stiffness increase more significantly with dry density, while the effect of the degree of saturation during compaction is much less significant.

You simply won't get as good of a result, as solid compaction as you will by laying down a couple of inches, compacting, then more stone. And you will spend less time compacting each layer anyway. If you do it in layers, it will be clear how much you need to lay down to get your desired depth.
