Filling Sample Pans
Filling Tips
♦ Level t he mixture on the top of the sample pan, spreading
the mixture out to the edges of the pan. The calibration
sample may be compressed with a piece of flat wood or flat
metal plate to ensure that the asphalt is level with the top of
the pan. Do not compact the sample with a press or
compaction tool!
♦ Place a piece of wax paper over the pan to prevent the
asphalt from sticking to the flat plate.
Filling Procedure
Use the forms in Appendix F to record the values.
1. Weigh the empty sample pan and enter the value on line H
2. Write the sample number and pan weight on the pan.
3. Enter the weight of the blank sample (line 3) on line J.
4. Add lines H and J and enter the total on line K.
5. Write the actual %AC (line G) on line L.
6. Place the preheated sample pan on a table and fill about 1/3
full (see Filling Tips).
7. Settle the asphalt mixture by tapping the pan on the table.
8. Lightly press the mixture with a spoon or spatula.
9. Continue adding the mixture in three layers, settling and
tamping each layer until the sample pan is full.
10. Place the sample pan on the scales and add or remove
material until the weight equals the weight on line K.
