A separate entry in this archive addresses stone dust as a joint-fill and leveling material, with a caution against using it as a structural base. Used correctly as a compacted surface path material in its own right — a different application entirely — stone dust produces a firmer, smoother walking surface than loose gravel, with a more formal, less rustic character.

A well-compacted stone dust path has a smooth, almost paved feel underfoot, firmer and less prone to scattering than pea gravel, with a uniform grey color that reads as more formal and more architectural than the warm tones of native gravel. It compacts to a surface nearly as firm as a paved path while remaining permeable.

Stone dust for path surfacing is compacted in thin lifts (1 to 2 inches) over a compacted crushed stone base, then sealed with a final compaction pass and sometimes a light watering to help bind the surface. This is distinct from using stone dust as the base itself — here it is specifically the finished wearing surface over a properly draining base below.

Properly compacted stone dust paths hold their surface well under foot traffic, resisting the loose, scattering behavior of pea gravel. They require occasional re-compaction and may need a fresh top dressing every several years as the surface wears, particularly in high-traffic areas.

Stone dust paths are correct where a firmer, more formal walking surface than loose gravel is desired, while retaining the permeability and traditional material character that paving would not provide. They suit formal garden settings and high-traffic connector paths differently than the looser character of pea gravel.
