system. The EDG automatically assigns numbers to newly-created Soil Models, Soil Tests, Job Sites,
and Field Tests.
Also, the user can assign names to Soil Models and Job Sites to help keep track of data. The operator
is required to manually keep track of the location that is associated with a particular Soil Test or Field
Test. A log or map might prove useful in keeping track of this data.
Note that these assigned names do not have to be unique, so the operator needs to avoid later
confusion. If a Soil Model or Soil Test is deleted, the Soil Model number or Soil Test number is not re-
used by the EDG.
Similarly, if a Job Site or Field Test is deleted, the Job Site number or Field Test number is not re-used
by the EDG.
For an untested type of soil, a Soil Model is created first. To create a Soil Model, EDG electrical testing
is performed at several (more than three) chosen Test Spots. For each Test Sport, the physical wet
density, dry density, and percent moisture is obtained by laboratory test.
Readings of two soil connection configurations are taken at a single Test Spot, the electrical results
of which are averaged and automatically stored to provide a unique electrical signature for that Test
Spat. Next, Sand Cone and Moisture laboratory tests are run on soil from the center of the Test Spot.
After the EDG soil darts are removed. This physical data obtained from the Sand Cone test will be
entered into the EDG and combined with the electrical data that was stored in the EDG when the
EDG testing was done on the Test Spot. In addition to the Sand Cone test, if compaction results are
desired from the EDG, a Proctor Mold test is required to determine the point of optimum moisture
content and maximum compaction. EDG will store Proctor Mold test data so that percent compaction
information can be computed.
When electrical and physical data for three or more Test Spots (Soil Tests) on the same soil type have
been accumulated, this Soil Mode must be associated with the particular project where the data was
gathered by pressing "Not associated" in the Project List menu. The Soil Model List will show all the
soil models.
The Soil Model data is kept in the EDG until deleted, so that it can be associated with other projects
as required. After a project has its Soil Model Completed and Associated, the EDG can be used to
test any other project that is constructed with this same soil type.
