PROCTOR/MARSHALL/VOIDLESS FUNCTION
The 3440-L gauge provides for up to four different Proctor values, four
different Marshall values, and one Voidless density value to be stored for
later use. These values are used to determine percent compactions. The
percent compaction calculations for Soil and Asphalt modes are as follows:
Soil mode (DD ÷ PR) × 100 = %PR
Asphalt mode (WD
÷ MA) × 100 = %MA
Asphalt mode 100 – [(WD
÷ VD) × 100] = %VOIDS
To select or change a Proctor, Marshall, or Voidless density value, press
the 〈PROCTOR/MARSHALL〉 key for the display:
MA=xxx.x PCF
PR=xxx.x
VD=xxx.x
Want to change?
If not, press 〈NO/CE〉. Then press 〈START/ENTER〉. The screen reverts
