What millings are
When roads are resurfaced, the old asphalt is ground off. Those crushed pieces — millings — still have some binder in them. Spread, watered and rolled, they knit into a surface much firmer than gravel or dirt, and they tighten up further in summer heat. Los Lunas summers help with that.
Where millings work well
- Long mesa-lot drives on sandy ground
- Farm lanes, barn approaches and hay storage
- Trailer, RV and equipment parking
- Shoulders beside asphalt to support the edge
- Overflow parking
Installed, not dumped
- Shape the subgrade with a crown and drainage
- Spread to an even depth
- Water and roll until tight
- Optional seal for a tighter surface
Dumped millings on loose sand without that prep end up as dark gravel. Done right, they stay firm. See millings driveways in Meadow Lake.
Common questions
Are millings as good as asphalt?
No — they're between gravel and asphalt. Firm and low-dust, but not as smooth or durable.
Do millings get firmer over time?
Yes. Traffic and summer heat help them bind.
Can I pave over them later?
Yes — compacted millings make a solid base.
