Lift thickness effects ability to compact mat density. Use the following tips to help in compaction.
Lift thickness effects ability to compact mat density. Use the following tips to help in compaction.
- Table 12 in Item 341 list minimum and maximum lift thickness
- The general rule of thumb 4 times the nominal maximum aggregate size
Thicker Lifts
- Thicker lifts are more difficult to achieve uniform density from top to bottom of the lift
- Try using higher amplitude
Thinner Lifts
- Thinner lifts are more difficult to achieve density
- Using rollers in vibratory mode may crush aggregate
- Try using static mode and lower amplitude
