Asphalt Truckload Calculator
Estimate whole dispatches, payload equivalents, and the final partial load from total asphalt tonnage.
Truckload inputs

How to interpret the result
Equivalent loads express tonnage divided by payload. Whole dispatches round upward because any remaining material requires another movement. Final-load weight is the remainder after full payloads.
Formula
Worked example
For 45 US tons and a 20-ton usable payload, the equivalent is 2.25 loads. Dispatch planning requires three trucks or trips: two 20-ton loads and a final 5-ton load.
Quick reference at 20 US tons per truck
| Total | Dispatches | Final load |
|---|---|---|
| 20 tons | 1 | 20 tons |
| 45 tons | 3 | 5 tons |
| 100 tons | 5 | 20 tons |
Common mistakes
- Rounding 2.25 payload equivalents down to two dispatches.
- Using rated capacity without checking legal and route-specific payload.
- Confusing truck count with delivery timing or material temperature control.
Confirm with carrier and supplier
- usable payload, axle limits, permits, route restrictions, and scales;
- minimum load, split-load policy, plant hours, and dispatch sequence;
- haul time, paving rate, backup trucks, rejected load handling, and tickets.

FHWA publishes a compilation of federal and state truck size and weight laws; actual legal payload remains vehicle- and route-specific. Obtain tonnage from the main calculator or parking lot calculator, and separate ordering decisions with the allowance guide.
