Asphalt Mix Temperature Loss at 21% mix temperature loss target rate: a worked example

This scenario runs the asphalt mix temperature loss calculation on the strong side: 21% mix temperature loss target rate, with every other input held at its documented default. a paving crew needs to know whether HMA or WMA will arrive hot enough for placement and compaction after the haul

The inputs for this scenario

  • Mix Temperature Loss affected amount: 315 units (unchanged)
  • Mix Temperature Loss total amount: 1.25 units (unchanged)
  • Mix Temperature Loss target rate: 21 % (raised for this scenario; the documented default is 18)

Working through the calculation

  • Applying the documented formula (Temperature loss = haul and wait time × cooling rate × weather/exposure multiplier) to the inputs above produces each figure below.
  • At this operating point the engine returns 289 °F delivered mix for estimated delivery temperature, the number this scenario is built around.
  • At this operating point the engine returns 26.25 °F for temperature loss.
  • At this operating point the engine returns 315 °F for loadout temperature.

How this compares with the baseline

  • Against the tool's baseline example, where mix temperature loss target rate sits at 18% and the headline result is 293 °F delivered mix, this scenario comes in 1.28% below the baseline at 289 °F delivered mix.
  • Use it when planning haul distance, deciding whether to tarp or use insulated trucks, or troubleshooting why a distant section failed density. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Estimated delivery temperature: 289 °F delivered mix (headline result)
  • Temperature loss: 26.25 °F
  • Loadout temperature: 315 °F
