The in situ field density and water content of soil and soil-aggregate base materials are critical parameters that affect the stability and performance of pavements, foundations, and other structures built on these materials. The test methods described in ASTM D4546-21 provide a means of determining these parameters in the field, allowing for the evaluation of the material's suitability for construction.

ASTM D4546-21 is a standard test method that provides guidelines for determining the in situ field density and water content of soil and soil-aggregate base materials. This standard is widely used in the construction industry to ensure that the soil or soil-aggregate base materials meet the required specifications for density and water content. astm d4546-21 pdf

The precision and bias of the test methods are discussed in the standard, including the sources of error and the limitations of the methods. The in situ field density and water content
