If you were to use just crushed limestone with no fines, the flagstone would have a good base, but not the best. The introduction of these fines is what allows the crushed limestone to mimic poured concrete. Without the fines there would be considerable void space between each of the larger pieces of limestone.

If your project calls for crusher fines, make certain that you're getting the right type that will give you the long term benefits of a weed free and stable surface and will insure a lifetime of use and enjoyment.
Quarry fines, defined by BS EN standards, are the inherent fraction of an aggregate passing 0.063 mm (63 microns). Many quarries also refer to their (sub-economic) fine aggregate (finer than 4 mm) as quarry fines (or quarry dust). The term is used here to denote both fine aggregate and quarry fines (material <63 microns). Quarry fines can be
