How much asphalt millings do I need?
Use Dimensions when you know the length and width, or switch to Enter area when you already know the square footage. Enter depth in the same material state you select: a finished compacted layer for Compacted, or a loose/uncompacted layer for Loose. The calculator converts that volume to tons and cubic yards.
The same task is often called an asphalt milling calculator, crushed asphalt calculator, or recycled asphalt calculator. The material label may vary, but the supplier's density and whether the quote is loose or compacted matter most.
Reclaimed asphalt pavement (RAP), asphalt millings, crushed asphalt, and asphalt grindings can vary by gradation, moisture, and condition. PaveMath starts with 140 lb/ft³ for compacted millings or 120 lb/ft³ for loose millings; replace the planning value with supplier or tested density when you have it. Waste is added only when you enter an allowance in the optional estimate options.
To estimate material cost, enter the current local price per ton. The result is for material quantity and material cost only; delivery, grading, base preparation, drainage, and compaction may be quoted separately. For background on recycled asphalt pavement, see the FHWA RAP overview.
Asphalt millings calculator by square feet: tons by depth
If you already know the driveway, parking pad, or pathway area, switch to Enter area and type the square footage directly. Use Dimensions when you know the length and width.
The reference table below shows calculated tons for common project sizes using the compacted planning assumption of 140 lb/ft³ with no waste allowance. Choose loose millings or add a project-specific allowance when your supplier or site conditions require it.

| Project size | Area | 3 in millings | 4 in millings |
|---|---|---|---|
| 20 x 20 ft driveway | 400 sq ft | 7.00 tons | 9.33 tons |
| 800 sq ft driveway | 800 sq ft | 14.00 tons | 18.67 tons |
| 1,000 sq ft driveway | 1,000 sq ft | 17.50 tons | 23.33 tons |
| 1,500 sq ft driveway | 1,500 sq ft | 26.25 tons | 35.00 tons |
How much area will asphalt millings cover?
Switch to Calculate coverage when you know how many tons or tonnes of millings are available. Enter the layer depth and material condition, and the calculator works backward from mass to material volume and then to coverage area.
Coverage depends on density and on the material state represented by the depth. Use supplier or tested density when available. If you add a planning allowance, the calculator reserves that fraction of the available quantity and reduces effective coverage rather than pretending the physical material disappeared.
Asphalt millings and crushed asphalt cost per ton
Asphalt millings are recycled asphalt material, but the price you pay depends on the local supplier, processing, screen size, pickup or delivery, and current supply. Enter the price per ton from a recent quote instead of relying on a national average.
The calculator shows material cost from the quantity and price you enter. Keep trucking, minimum loads, grading, base preparation, drainage, spreading, and rolling as separate quote items so a low material price does not hide a higher delivered cost.
Asphalt millings driveway depth and coverage
Many driveway and path estimates start around 3 to 4 inches of finished compacted millings, while parking pads or heavier-use areas may need a different section. When Compacted is selected, enter that finished compacted depth. When Loose is selected, enter a loose/uncompacted layer depth instead. The correct section still depends on the base, drainage, soil, and traffic; the calculator converts the depth you provide and does not design the pavement structure.
Keep the entered depth and density in the same selected material state, and compact driveway material in controlled lifts with equipment suited to the job. A weak base, standing water, or poor drainage will not be fixed by adding more millings.
Plan loose delivery and compacted coverage separately
The calculator keeps depth and density in the same selected material state. Use Compacted for a finished compacted layer, or Loose when both the entered depth and density describe loose/uncompacted material. A supplier may quote loose truckload volume while your driveway plan is compacted, so confirm the supplier’s conversion basis before ordering rather than mixing the two states.
For a small or irregular driveway, delivery and grading can cost more than the recycled material. Ask for the product type, screened or unscreened grading, unit weight, truck capacity, spreading, rolling, drainage work, and any minimum load in the quote.
Use the asphalt compaction calculator to check a loose-to-compacted thickness factor, read the asphalt millings driveway cost guide, and compare the road base calculator when millings are part of a larger base plan.

FAQ
How do you calculate asphalt millings tonnage?
Multiply your project's width by its length in feet to get the area. Multiply this by the entered thickness in inches and divide by 324 to calculate base cubic yards. Choose compacted or loose millings to select the planning density, then multiply cubic yards by 27 and density and divide by 2,000 to get tons. An optional waste factor is applied only when you enter one.
How many tons of asphalt millings do I need?
Use Dimensions when you know the length and width, or Enter area when you already know the square footage. Enter depth in the same material state you selected: finished compacted depth for Compacted, or loose/uncompacted depth for Loose. The calculator converts that volume into tons and cubic yards, then applies an optional ordering allowance only when you enter one.
How many tons are in a cubic yard of asphalt millings?
At the calculator's compacted planning density of 140 lb/ft³, one cubic yard weighs about 1.89 tons. At the loose planning density of 120 lb/ft³, it weighs about 1.62 tons. These are planning values; gradation, moisture, and compaction change the actual weight, so use the supplier's density when available.
What unit weight should I use for asphalt millings?
The calculator uses 140 lb/ft³ for compacted millings and 120 lb/ft³ for loose millings as transparent planning assumptions. Replace the automatic value with a supplier or tested density in Optional material details when you have project-specific data.
How much area does one ton of asphalt millings cover?
At the calculator's compacted planning density of 140 lb/ft³ and with no optional planning allowance, one ton covers about 57 square feet at 3 inches thick or 43 square feet at 4 inches thick. For your own quantity, switch to Calculate coverage and enter the available tons, depth, material condition, and supplier density when available. Coverage changes with density and the material state represented by the depth.
Why should I add a waste factor for crushed asphalt grindings?
Use the waste field as a planning or ordering allowance when you want extra material beyond the calculated base quantity. In Amount mode it increases the quantity to order; in Coverage mode the same allowance reserves part of the available quantity and therefore reduces the design coverage. Leave it blank or enter 0 when you do not want an allowance.
Do asphalt millings need compaction?
Yes. For a stable driveway or parking area, spread the millings and roll them thoroughly with a heavy rental roller or vibrating plate compactor. Compacting millings helps them lock together, forming a hard gravel-like surface.
How much do asphalt millings cost per ton?
Asphalt millings are recycled material and cost significantly less than new hot-mix asphalt. They usually cost between $10 and $55 per ton, depending on local highway project supply and trucking distance.
What is the difference between screened and unscreened asphalt millings?
Screened asphalt millings have been passed through a mechanical screen to remove oversized chunks and debris, producing a more uniform particle size. Screened millings compact more evenly and are better suited for driveways and paths where a smooth finish is desired. Unscreened millings cost less but may contain larger fragments that require additional grading before compaction.
Are asphalt millings and crushed asphalt the same thing?
In many driveway estimates, crushed asphalt, recycled asphalt, asphalt grindings, and asphalt millings refer to the same general reclaimed asphalt material. Suppliers may screen or size the material differently, so confirm the local product and use the density field if your supplier gives you a unit weight.
How much asphalt millings do I need for a driveway?
Measure the driveway length and width and use Dimensions, or switch to Enter area if you already know the square footage. Match the selected material condition to the depth you enter, and use supplier density when available. Many compacted driveway planning estimates start around 3 to 4 inches, but the base, drainage, soil, and traffic determine the appropriate section.
Can I use this as a crushed asphalt calculator?
Yes. Crushed asphalt, asphalt millings, recycled asphalt, RAP, and asphalt grindings can describe similar reclaimed material, but the supplier's grading and density still control the estimate. Enter dimensions or area, then use a depth and density that describe the selected material condition to calculate tons and cubic yards.
