: Unlike the first two methods, Method C focuses on what happens after the soil has already swelled or collapsed. It measures how much more the soil will compress when additional structural loads (like a new building) are applied to the already-wetted ground. Key Parameters Measured

: This method uses soil that has been remolded or compacted in the lab. It is primarily used to simulate the behavior of compacted fills . It is also the standard way to determine Swell Pressure (the force required to prevent swelling) and Free Swell (the percentage of expansion under minimal load). astm d454621 pdf

: This procedure uses "undisturbed" or intact samples taken directly from natural deposits or existing fill. It measures how a specific point in the soil profile will react to wetting while under its in-situ vertical stress. : Unlike the first two methods, Method C
