Refined tolerances for consolidometer components, porous stones, and deformation gauges to minimize machine deflection errors.

Rigid, corrosion-resistant ring (usually stainless steel or brass) to maintain strict one-dimensional lateral restraint.

: This method determines the precise magnitude of free swell, swell pressure, and hydrocompression across a multi-point stress continuum to simulate how an artificial embankment or structural fill will behave after construction. astm d454621 pdf

The key features and benefits of ASTM D4546-21 include:

This method measures the free swell of a soil sample under a minimal seating load, followed by incremental loading to determine the swell pressure. The key features and benefits of ASTM D4546-21
