Indicates the exact amount of heave or hydrocompression that will occur when a specific depth of soil is fully inundated. 3. Test Method C (Loading After Wetting)
Using the most current version ensures that your lab testing complies with the latest industry best practices and that your data is legally and technically defensible. astm d454621 pdf
ASTM D4546-21 establishes laboratory methods to quantify the one-dimensional swell or collapse of unsaturated soils upon wetting, providing critical data for geotechnical engineering. The standard outlines three test methods (A, B, and C) to determine swelling pressure, free swell, and hydrocompression potential in soils. To access the full standard, purchase the document from ASTM International ASTM International Indicates the exact amount of heave or hydrocompression
The standard provides three distinct ways to test soil, depending on your project needs: : Uses multiple reconstituted (compacted) specimens to simulate new fill. : Uses a single ASTM D4546-21 establishes laboratory methods to quantify the
The ASTM D4546-21 standard is available in PDF format from various sources, including:
ASTM D4546-21 is the current industry standard for laboratory measurement of one-dimensional swell or collapse potential in cohesive soils, providing methods for testing reconstituted and intact samples. Released in April 2021, this update refines unit systems and terminology for evaluating ground heave and hydrocompression.
