ASPHALT MODE, % MARSHALL. If % Marshall (or % compaction
compared to a Marshall target) is required, press
〈1〉 from the last display
on page
2–6.
% Marshall = (WD/Marshall) × 100
To enable % Voids, press 〈YES〉.
% VOIDS = 100 × [1 – (WD/Voidless)]
NOTE
For the gauge to calculate % Voids, a voidless density must be
entered into the gauge as described on page 5–15. The voidless
density is the maximum theoretical density, or Rice test result.
After a brief delay, the screen display returns to the READY display.
ASPHALT MODE, 100 – %MA. If 100 – %MA is required, press 〈2〉
from the last display on page 2–6.
NOTE
The term % Voids is defined as 100 – %Voidless.
100 – %MA = 100 × [1 – (WD/Marshall)]
To enable % Voids, press 〈YES〉.
%VOIDS = 100 × [1 – (WD/Voidless)]
After a short delay, the display returns to READY. Chapter 4 provides
instructions for taking measurements in Asphalt mode.
