Truck Fleet — Belly-Dump / Windrow
Trucks required for belly-dump / windrow from haul distance, speeds and plant rate.
Windrow paving decouples trucks from the paver entirely — belly dumps drop and leave, the pickup machine feeds continuously. Truck turn time falls by the whole paver-wait term, which is why high-production rural work runs this way wherever specs allow.
Formula
Note: Paving estimates only — the project mix design, agency specification and the plant's QC data govern. Temperature models are simplified; verify with an infrared gun and density gauge on the mat.

About Truck Fleet — Belly-Dump / Windrow
Truck Fleet — Belly-Dump / Windrow computes the governing relationship cycle = 2d/v + ends · N = TPH ÷ (payload/cycle) live as you type. Windrow paving decouples trucks from the paver entirely — belly dumps drop and leave, the pickup machine feeds continuously. Truck turn time falls by the whole paver-wait term, which is why high-production rural work runs this way wherever specs allow. Defaults are pre-filled with realistic values for this exact scenario, and the worked example substitutes your numbers step by step so the math is never a black box.
How to use Truck Fleet — Belly-Dump / Windrow
- 1Enter your values — One-way haul distance, Average haul speed, Load + ticket time, Unload/paver time and more (sensible defaults are pre-filled).
- 2Read the live results: Cycle time, Trucks required, Mix on the road at any time.
- 3Check the "with your numbers" line to see cycle = 2d/v + ends · N = TPH ÷ (payload/cycle) substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
Why use Truck Fleet — Belly-Dump / Windrow?
- ✓Instant, free and private — every calculation runs client-side in your browser; nothing is uploaded
- ✓Built on the stated formula cycle = 2d/v + ends · N = TPH ÷ (payload/cycle) with authoritative sources cited on the page (NAPA — HMA paving handbook & best practices)
- ✓Windrow paving decouples trucks from the paver entirely — belly dumps drop and leave, the pickup machine feeds continuously.
- ✓SI ⇄ Imperial toggle converts your inputs in place, so you can work in the units your drawings use
Frequently asked questions
What formula does the truck fleet — belly-dump / windrow use?+
It evaluates cycle = 2d/v + ends · N = TPH ÷ (payload/cycle), exactly as published. Sources: NAPA — HMA paving handbook & best practices. The substituted worked example on the page lets you verify every step against the textbook.
How should I read the result — and how far can I trust it?+
Windrow paving decouples trucks from the paver entirely — belly dumps drop and leave, the pickup machine feeds continuously. Paving estimates only — the project mix design, agency specification and the plant's QC data govern. Temperature models are simplified; verify with an infrared gun and density gauge on the mat.
When is this calculator the right tool for the job?+
Trucks required for belly-dump / windrow from haul distance, speeds and plant rate. A free asphalt paving temperature & logistics tool. Truck turn time falls by the whole paver-wait term, which is why high-production rural work runs this way wherever specs allow. For neighbouring scenarios, the related tools below cover the same engine with different presets.
Does it support both metric and imperial units?+
Yes — the SI ⇄ Imperial toggle converts the values already in the fields, preserving the physical quantity, so you can flip mid-calculation without re-entering anything.
