When you’re buying bulk materials like asphalt millings, #57 stone, or crusher run, a lot of it can look the same at first.
But in reality, these materials behave very differently — and choosing the wrong one is one of the fastest ways to waste money on a project.
Most people searching for terms like crusher run near me, #57 stone for drainage, or asphalt millings for driveway are already planning a job. The only thing left is picking the right material.
This guide breaks it down in plain terms so you know exactly what to use and when.
Screened vs Unscreened Asphalt (Millings)
Asphalt millings are recycled asphalt, but how they’re processed makes a big difference.
Screened Asphalt Millings
Screened millings are processed to remove oversized chunks and create a more consistent size.
They’re typically used for:
- Driveways
- Parking areas
- Surfaces where you want a cleaner finish
Because the material is more uniform, it spreads easier and compacts better, giving you a tighter, more finished surface.
Unscreened Asphalt Millings
Unscreened millings are more raw. You’ll get a mix of fine material and larger chunks.
They’re usually used for:
- Base layers
- Rural or temporary roads
- Projects where appearance doesn’t matter
They’re cheaper, but less predictable. You may need extra grading or additional passes to get a smooth result.
#57 Stone vs Crusher Run
These two get confused all the time, but they serve completely different roles.
#57 Stone
#57 stone is clean, mid-sized gravel (around ¾”–1”) with no dust.
It’s best for:
- Drainage (French drains, around foundations)
- Areas where water needs to move
- Under concrete in some applications
Because it has no fines, it doesn’t compact tightly — which is exactly why water can flow through it.
Crusher Run
Crusher run is a mix of crushed stone and stone dust.
It’s best for:
- Driveway base
- Road base
- Foundation support
The dust fills the gaps between the stone, allowing it to compact into a hard, stable surface.
If you need something to actually hold weight — this is usually the better choice.
Best Use Cases (Real-World)
Here’s what actually works on real jobs:
- Driveway (long-term) → Crusher run base + screened asphalt on top
- Cheap driveway option → Screened asphalt only
- Drainage system → #57 stone only
- Base under patio or slab → Crusher run
- Temporary road or access → Unscreened asphalt
Worst Use Cases (What to Avoid)
This is where people lose money:
- Using #57 stone as a base → it won’t compact, things shift
- Using crusher run for drainage → traps water
- Using unscreened asphalt as a finish layer → rough, uneven surface
- Using screened asphalt without prep → can fail if base is weak
How to Choose the Right Material (Real Setup Guide)
If you’re unsure, don’t just pick one material — think in layers.
Most solid projects use a combination.
Driveway (Best Long-Term Setup)
If you want something that actually lasts:
- Base layer → Crusher run (4–6 inches, compacted)
- Top layer → Screened asphalt millings
Why this works:
- Crusher run gives you a solid, compact base
- Screened asphalt gives you a smooth, driveable surface
👉 This is the best balance of cost + durability
Budget Driveway Option
If you want cheaper and faster:
- Base → Unscreened asphalt millings
- Top → (optional) Screened asphalt
Why:
- Unscreened fills gaps and builds thickness cheaply
- Screened on top improves the finish
👉 Good for rural or temporary driveways
Drainage Projects (French Drain, Around Foundation)
Keep it simple:
- Use #57 stone only
Why:
- It allows water to flow freely
- No fines = no clogging
⚠️ Don’t add crusher run here — it will trap water
Patio / Paver Base
- Base → Crusher run (compacted)
- Second layer → Concrete / mason sand
- Top → Pavers
👉 Do NOT use #57 stone as your base here — it won’t lock in
When You CAN Use #57 for Pavers?
It works well if:
- You want a permeable patio
- You install 4–8+ inches of stone
- You compact in lifts
- You use a proper bedding layer (sand or chip stone)
- You have edge restraints
👉 This is closer to commercial / pro installs
Rough Base / Fill Areas
If you’re just building up ground:
- Start with unscreened asphalt
- Compact
- Add better material on top if needed
👉 This saves money when finish doesn’t matter
Simple Rule to Remember
- Crusher run = structure (holds weight)
- #57 stone = drainage (moves water)
- Screened asphalt = surface (drive on it)
- Unscreened asphalt = bulk fill (cheap base)
