Direct answer
The compaction window is the time and temperature range where the mat can be compacted effectively before it cools too far for the roller pattern to work.
What to capture
- Mix type, lift thickness, delivery temperature, and ambient conditions.
- Breakdown, intermediate, and finish rolling times.
- Temperature checks and any delay reason.
- Density result or acceptance note.
FAQ
Why track the compaction window?
Tracking the window helps explain density results, weather impacts, rolling sequence decisions, and disputed acceptance outcomes.
