SOIL MODE
To measure the moisture and density of soil, soil-stone aggregate,
and similar materials, follow the steps below:
✓
Prepare the test site as described on page 4–7.
✓
Place the gauge on the test area.
✓
Insert the source rod into the hole made by the drill rod or
source rod adapter.
Use care when inserting the source rod. Try
not to disturb the soil around the hole.
✓
Lower the source rod to the measurement depth. Release the
trigger. Gently push down on the handle over the source rod to
lock the source rod into position. You should hear a
click when
the source rod locks into position.
✓
Gently slide the gauge to the right (towards the Troxler logo) so
the source rod makes contact with the wall of the hole.
✓
Press the

button on the RoadReader Plus
main menu (see Figure 3–11).

In the Manual depth mode (see page 5–10), the PDA
prompts for the source rod depth. Enter the source rod depth
and press the
〈

〉
button.

In the Automatic depth mode, the gauge software reads the
source rod depth strip to determine the source rod depth.

Note that the Proctor value is based on soil particles 3/8
inches or less in diameter (or those passing a #4 sieve). If an
unusual reading is obtained and oversize particles are
suspected, rotate the gauge 90
°
. Use the same drill hole to
take a second reading.
