Standard Specification for In-Place Density and Moisture Content of Soil and Soil-Aggregate by Nuclear Methods (Shallow Depth) standard by American Association of State and Highway Transportation Officials, 2011
This test method describes the procedure for determining the in-place density and moisture of soil and soil-aggregate by use of nuclear gauge. The density of the material may be determined by either direct transmission, backscatter, or backscatter/air-gap ratio method. The moisture of the material is determined only from measurements taken at the surface of the soil (i.e., backscatter).
