Stone Dust Under Pavers

[NE Surfer]

Hi All - getting close to finishing prep on the new pool.
I have read conflicting suggestions on whether to put a layer of stone dust under the pavers that will support the uprights.
I have 16 x 8 x 4 concrete pavers and I live in MA - so will have freeze / thaw conditions.
Is putting 2” of stone dust under the pavers at this point helpful or just “extra work”?
My soil is fairly typical fill, not too sandy and minimal clay with plenty of typical rocks / pebbles. I have encountered more clay as I dished out the middle 16”, but nothing there that looks like I could make pottery with.

That is all extra. I had clay and my pavers never moved. I also freeze solid every year.

The professionals in my area just use stone dust no pavers (Montreal)

Thanks for the responses.
So fair to say that with a 4” pavers set on firm, packed ground, the stone dust would be “unnecessary”?

anyone have a negative experience using pavers WITHOUT stone dust?

We never used stone dust. Uprights on the pavers, the large posts with the pressure plates required cinder block for the hard-sided pool. All on heavy clay.

thanks everyone for the replies!

getting there with my leveling... will be sinking the pavers this weekend... hopefully!
