Asphalt Weight Calculator
Calculate exactly how much your asphalt project weighs in tonnes or pounds — the figure you need for ordering, delivery, and load planning.

| Stone Mastic Asphalt | 6.5% - 7.5% |
Asphalt weight matters beyond just ordering the right quantity — it also determines how many truckloads a delivery will take, since trucks have maximum legal payload limits, and it affects load calculations for structures like bridges or parking decks where pavement weight is part of the design load.
Standard density assumptions for weight calculations
Compacted hot mix asphalt is commonly assumed at around 145 lb/ft³ (approximately 2,322 kg/m³) for planning purposes in the US, though actual density varies by specific mix design. Always use your supplier’s stated density where precision matters, particularly for large orders where a small density error compounds into a meaningful weight discrepancy.
| Volume | Weight at 2,322 kg/m³ | Weight in US Tons |
|---|---|---|
| 1 m³ | 2,322 kg | 2.56 tons |
| 10 m³ | 23,220 kg | 25.6 tons |
| 50 m³ | 116,100 kg | 128 tons |
| 100 m³ | 232,200 kg | 256 tons |
How many truckloads will this be?
Standard dump trucks typically carry 10–16 tons of asphalt per load depending on truck size and local weight regulations. Once you have a total tonnage figure from this calculator, divide by your expected per-truck payload to estimate the number of deliveries needed — useful for scheduling and coordinating with your paving crew’s laying rate.
Hot mix cools during transport — plan around it
Weight calculations are independent of temperature, but if you’re scheduling multiple truckloads, remember that hot mix loses workable temperature during transit — coordinate delivery timing with your paving crew’s laying and compaction speed, not just the raw tonnage math.
Weight vs volume: which one to order by
Asphalt is almost universally bought and delivered by weight (tons/tonnes), not volume, since weight is what a weighbridge measures and what a supplier invoices. Use this calculator’s weight output as your ordering figure, and treat the volume output as an intermediate step in the calculation rather than the number you’d actually quote to a supplier.
Legal load limits and permit considerations
Truck weight limits are set by local and national road authorities and vary by axle configuration and jurisdiction — exceeding them risks fines and, more importantly, road and bridge damage. If your project involves unusually large single-day tonnage (a big commercial lot poured in one session, for example), check with your supplier or hauler about local gross vehicle weight limits before finalizing a delivery schedule, since it may affect how many trucks you need and how deliveries are staged throughout the day.
