A Guide to ASTM D4546-21: Standard Test Methods for by Use of the Pressing and Triaxial Cell (Withdrawal)
Overview
This standard (Active Standard D4546-21) covers three alternative methods for determining the magnitude of one-dimensional swell or collapse of compacted or intact soils when subjected to changes in wetting and stress conditions. It is essential for geotechnical engineering applications involving foundations, embankments, and road subgrades.
1. Standard Identification
- Full Title: Standard Test Methods for One-Dimensional Swell or Collapse of Soils
- Designation: ASTM D4546-21
- Year of Approval: 2021
- Supersedes: ASTM D4546-14
- Organization: ASTM International, Committee D18 (Soil and Rock)
Swell Pressure: The minimum vertical stress required to prevent a soil from expanding when wetted.
Lab tests utilize full inundation, creating an extreme saturation state (
Standards Aggregators: Sites like IHS Markit (S&P Global) or ANSI provide licensed copies.
Avoid: Random PDF sharing sites (like z-lib or Academia.edu for this specific standard). ASTM has legal teams that issue takedown notices and, in rare cases, pursue legal action against organizations hosting pirated standards.
