This method is often referred to as a "wetting-after-loading" test on multiple specimens. The resulting data can be used to estimate the total one-dimensional heave or settlement of the ground surface after a fill has been constructed and becomes fully saturated.
Determining the required foundation pressure (pressure to prevent swell) to keep the soil stable. Method C: Loading-After-Wetting

As the soil attempts to expand, the operator (or automated system) increases the vertical load to keep the specimen at its initial height.
The primary objective of ASTM D4546-21 is to measure the magnitude of (vertical movement) that occurs when an unsaturated soil sample is exposed to free water. The standard covers two main moisture-induced phenomena: This method is often referred to as a
Carefully trim an undisturbed or compacted soil sample into the consolidometer ring. Take initial measurements of weight, height, diameter, and moisture content.
The ASTM D4546-21 standard has significant implications for the geotechnical engineering industry. By providing a standardized framework for determining the in situ field density and moisture content of soil and soil-aggregate base materials, the standard: Take initial measurements of weight, height, diameter, and
