Producing a soil Model to develop an accurate soil model, it is suggested that you either use an area of the Job site where the material to be tested has already been placed and compacted or a similar site, which has identical compacted material in place.
To quantify readings made with the edg while developing the soil model, it is necessary to run a conventional method test (nuclear gauge, sand cone, Voluvessel or drive tube and Moisture tests) at the same time. if you are going to use a nuclear gauge for this, it is recommended you still do an alternate test for moisture, such as oven-dry, speedy or field burn off. this correlates actual compaction and moisture numbers to the readings obtained with the edg, which provides the information the edg needs to make accurate determinations by itself. this regimen only needs to be done to develop a soil Model.
Select areas on the Job site where the type of soil is consistent from place to place, and where there are differences in water content and compaction. special preparation of spots of different densities or water contents should be done the day before, so as to allow stabilization of the soil water content.
A matrix of six (6) spots should be used during the soil model calibration procedure, which consists of two different soil density conditions and three (3) water content conditions that cover the range that is expected to be measured. the three calibration tests that evaluate high density soil will use test locations that ideally will have soil conditions that are close to the maximum density as determined by test Methods d1557 or an equivalent method. the range in water content should include low water content, middle range water content, and high water content that is near the optimum water content as determined by test Methods d1557 and d2216 or equivalent test methods.
Once the soil Model is developed, the edg is ready to use by itself anytime this specific tested material is used. additional readings (points) can always be added to the initial soil Model. this allows you to provide more points from which your curve is developed, refining it and making it more accurate.
