Readiness check

Is your asphalt paving day ready to go?

Density is won or lost in the minutes the mat is hot, and most of what decides it is set before the paver moves: the window you have, the tack you pulled, the roller train, and the plan for the joint. Answer for the mat you have coming. The score is computed on your device; add an email only if you want the paving-day checklist sent over.

1. Do you have the compaction window for today's conditions (delivery temp, lift thickness, base temp, wind)?Yes, we ran a cooling estimate and know our minutes to the cessation tempWe know it is short but have not put a clock on itNo

2. Is the breakdown roller set to work tight behind the paver in the hot zone?Yes, breakdown stays in the hot zone and builds most of the densityIt rolls but tends to drift back off the paverNo set plan

3. Is the tack coat applied at the right rate and broken before paving over it?Yes, tack is applied to spec and allowed to break to brown/tackyTack went down but we pave over it wet or heavyNo tack plan

4. Are the ambient and surface temperatures above the spec minimum for this lift?Yes, checked against the spec minimum for the lift thicknessIt feels warm enough, not checked against the specBelow or unsure

5. Is the longitudinal joint construction planned (overlap, rolling, or a notched wedge)?Yes, the joint method and its rolling are planned and will be density-testedWe will figure the joint out as we goNo joint plan

6. Is trucking and mat handling set to avoid segregation and temperature differentials?Yes, consistent trucks, a material transfer or windrow plan, no cold chunksTrucks are loose and the mat sometimes shows streaksNo plan for segregation

7. Do you know the Gmm and have the density gauge correlated for acceptance?Yes, Gmm is in hand and the gauge is correlated to coresWe have a gauge but no correlation or current GmmNo density plan

8. Is someone recording mat temperatures, rolling, and density as the work runs?Yes, temps and rolling are logged so a light core is defensibleSome notes, not consistentNo documentation
