The problem is the crush and run - or "crusher run" as I've heard it called - is compact-able - and 57 stone - gravel - naturally is compacted when it's dumped/spread. so you have the chance of settlement under/of the concrete and or cracking of a slab with a compact-able sub-base - unless you are able to fully compact it in lifts - layer by layer.

CEMENT - SAND - STONE relationship; In practice a 50kg of cement bag contains 2 head pan of cement; this means that if i have a plan to mix 1 bag of cement my mixing ratio would be: 1:2:4 = 1 bag of cement : 4 head-pans of sand : 8 head-pans of stone. 1:3:6 = 1 bag of cement : 6 head-pans of sand : 12 head-pans of stone.

1)- Workability - It is defined as the ease with which we can work with concrete. So when we use quarry sand in concrete, due to its heavy weight it reduces the workability of concrete. 2)- Mixing - Due to its heavy weight and large particles, it doesn't mix properly in concrete. 3)- Price- Price of quarry sand is lower than price of river sand.

Any aggregate that has particles of the same size will drain well. Usually pavers are set on sand, not stone; sand is easier to work with and still drains well, and you can dust sand over the surface of the pavers to fill in the gaps. If you try to do that with a stone base the sand will just run through and fill the voids in the crushed stone.
