About asphalt millings
Asphalt millings are ground-up old pavement. When compacted and warmed by sun they bind into a fairly firm surface, which is why they are popular for rural drives and lots. Expect the weight to fall in the range of 1.2 to 1.4 loose tons per yard.
Getting the order right
- Measure odd shapes in pieces. Split curves and L-shapes into rectangles and add them.
- Add a margin. About 10 percent covers compaction and low spots.
- Bulk or bags. Bulk delivery is the practical choice here.
- Prep first. Remove sod, compact the subgrade and set edging before the stone arrives.
Use the volume and tonnage calculator for any other size.
When to choose asphalt millings
Works well for:
- Rural driveways and farm lanes
- Parking areas where a dust-free surface is wanted
- Low-cost base under a future paved surface
Less suited to:
- Areas near wells or streams where local rules limit them
- Decorative or barefoot areas
- Jobs needing a uniform, clean look
Quick reference numbers
- Per inch over 100 sq ft: about 0.40 tons of asphalt millings (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.0 tons.
- Another size for comparison: a 12x24 area at 3 inches takes about 3.5 tons.
- Weight used here: about 1.3 tons per cubic yard.
Mistakes that throw off the order
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
