Paving QC — Rain Shutdown Decision
Rain Shutdown Decision for paving quality and operations decisions.
Rain calls get made on gut and argued on memory; this expected-value frame settles them in thirty seconds. Note what's NOT in it: paving INTO rain ruins mat quality beyond the mix cost — when drops are already falling, the calculation is moot and the answer is stop.
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.
Rain Shutdown Decision for paving quality and operations decisions. A free asphalt paving temperature & logistics tool — no sign-up, no upload, instant results in your browser.
About Paving QC — Rain Shutdown Decision
Paving QC — Rain Shutdown Decision computes the governing relationship E[loss] = P(rain) × exposure × $/t vs crew standby live as you type. Rain calls get made on gut and argued on memory; this expected-value frame settles them in thirty seconds. Note what's NOT in it: paving INTO rain ruins mat quality beyond the mix cost — when drops are already falling, the calculation is moot and the answer is stop. 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 Paving QC — Rain Shutdown Decision
- 1Enter your values — Mix in transit + queued, Mix value, Crew standby cost, Rain probability next hour (sensible defaults are pre-filled).
- 2Read the live results: Expected loss if you push on, Cost of a 1-h hold.
- 3Check the "with your numbers" line to see E[loss] = P(rain) × exposure × $/t vs crew standby substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
