APPENDIX F: MISSION STATEMENT TO
THE WISCONSIN NATIONAL GUARD
Wisconsin National Guard Mission Statement
TEST AND EVALUATION PLAN FOR
RAPID STABILIZATION OF THAWING SOILS
Cold Regions Research and Engineering Laboratory (CRREL)
Presented to the Wisconsin National Guard
MISSION
In partnership with Wisconsin National Guard, Fort McCoy and the USDA
Forest Service, CRREL is conducting a test and evaluation of several expedient
stabilization techniques for building temporary roads and trails on thawing soil
for the U.S. Army. Test sections will be constructed at three different locations: a
wooded trail, 12% slope, and level curves. After each test area is completed, the
sections will be trafficked and evaluated.
The Wisconsin National Guard Unit will construct and evaluate these test
sections using the guidance provided below and by CRREL personnel on-site. An
overview of the test and evaluation scheduling is given in Figure F1. A briefing
will be held at the site on March 16 to provide any necessary training, answer
questions and go over details and last minute changes.
PRETESTS (March 16)
Prior to building the test sections, pretests will be conducted on two tech-
niques. A small rubber tired vehicle will traverse 50 passes on a small section of
the tire chips to determine if tire punctures will be a problem. The tire chip
pretest will require a loader, a pick-up truck and one assistant. The test will
occur where the tire chips are stockpiled. The other pretest will consist of driving
a tank on several different geosynthetics about 50 ft long to see if they can
withstand the aggressive tank track during turning. National Guard (NG) sup-
port is required for both of these tests. The geosynthetic pretest will require
three laborers and a 4-wheel-drive vehicle, preferable a pick-up truck. Ft.
McCoy will provide a tank and driver.
TEST SECTIONS
Test sections should be approximately 12 to 14 feet wide and range in length
from 50 to 150 feet long (additional length can be added to fill in remaining holes
so that the entire road is traffickable). The following test sections will be con-
structed:
1. Chunkwood, 8 in. thick,
a) with added sand,
b) without added sand
2. Chunkwood, 16 in. thick,
a) with added sand,
b) without added sand
3. Tire chips 12 in. thick
