Yes — topping old gravel is the standard refresh: fix the surface first, then add about 2 inches of new stone. Regrade what's there, fill potholes and wheel ruts so they don't telegraph through, and match the new stone to the old size class so the layers knit instead of floating apart. If the old surface has gone soft or muddy, fix drainage first — new stone sinks into a wet base.
The refresh sequence
- Rake or regrade the old surface, restoring the crown
- Fill holes with matching material and compact them
- Top with about 2" of new stone — roughly 6 cubic yards per 1,000 sq ft
Midsummer is a fine time for it — dry stone spreads easily. Browse driveway gravel and size the top-up with the material calculator.
