Truck Fleet — RAP Backhaul Cycle
Trucks required for rap backhaul cycle from haul distance, speeds and plant rate.
Mill-and-fill jobs can run trucks loaded both ways — millings back to the plant, mix out to the road. The cycle gains a loading step but deletes an empty leg; where the plant accepts RAP at the gate, the same fleet covers both flows and the haul cost nearly halves.
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 — RAP Backhaul Cycle
Truck Fleet — RAP Backhaul Cycle computes the governing relationship cycle = 2d/v + ends · N = TPH ÷ (payload/cycle) live as you type. Mill-and-fill jobs can run trucks loaded both ways — millings back to the plant, mix out to the road. The cycle gains a loading step but deletes an empty leg; where the plant accepts RAP at the gate, the same fleet covers both flows and the haul cost nearly halves. 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 — RAP Backhaul Cycle
- 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 — RAP Backhaul Cycle?
- ✓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)
- ✓Mill-and-fill jobs can run trucks loaded both ways — millings back to the plant, mix out to the road.
- ✓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 — rap backhaul cycle 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?+
Mill-and-fill jobs can run trucks loaded both ways — millings back to the plant, mix out to the road. 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 rap backhaul cycle from haul distance, speeds and plant rate. A free asphalt paving temperature & logistics tool. The cycle gains a loading step but deletes an empty leg; where the plant accepts RAP at the gate, the same fleet covers both flows and the haul cost nearly halves. 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.
