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 covers the determination of the low-pressure air permeability of paper and paperboard. This test is essential in evaluating the porosity and breathability of paper and paperboard, which are critical properties in various applications, such as packaging, printing, and filtration. astm d4546-21 pdf
