ASTM D6938 Compliant Nuclear Density Gauge for Accurate Soil Compaction Testing

USAGE OVERVIEW

The Non-nuclear soil density gauge (EDG) accurately measures soil density,

moisture content and compaction in roads and foundations. The measurement

accuracy depends mainly on the correct use of the operator, so a detailed reading of

this operating manual will be available. Help you to use the product better.

Equipment Operation

Some new technologies that you need to be familiar with during the operation of EDG

are introduced.

1. Soil model is the combination of soil electronic data and soil physical data input by

users, and it is the basis of testing soil parameters in a similar soil characteristic area.

2. When making a soil model, EDG is needed to collect electronic signals at different

test points (the test point of this soil model is called soil test). Each test point needs to

collect an electronic signal. At the same time, sand cone test is needed to obtain the

physical characteristics of the soil, such as wet density, dry density and moisture

content. The maximum dry density of the soil is measured in the laboratory, and then

these data are input into the instrument so that the electronic data can be correlated

with the physical data.

3. At least three test points (soil test) are required for soil moulding. The more test

points, the more representative the soil model will be. Moreover, the larger the density

and water content range covered by the test points, the more accurate the soil model

is.

4. After the soil model is made, EDG can be used for field test. The test area is the

area where the experimenter intends to test and the tested soil has the same physical

characteristics.

5. A soil model is usually made for each different test area. Different projects need

different soil moulids. Once the soil model representing this area is successfully made,

the soil characteristics of any test point can be quickly and accurately measured by

EDG through field test.

6. The actual test is to calculate the physical properties of soil by comparing the

electronic data collected from the test points with the soil model.

7. It could add GPS as requirements.
