Schmertmann's Swell Sensitivity — Revisited
In perhaps one of his less famous papers, Schmertmann (1969) introduced the concept of Swell Sensitivity as the ratio of the swelling behavior of a remoulded soil to the swelling behavior of the same soil in the undisturbed state. In effect, this Technical Note, which appeared in Geotechnique, essentially established the importance of inherent soil structure and natural bonding on the swelling potential of fine-grained soils. Observations made by Schmertmann and presented in the Note showed that some remoulded soils which have lost their natural structural bonds through simple mechanical remoulding have a higher swelling potential than the undisturbed soil. In the author's opinion, this paper is an important but lesser appreciated paper, in part because of the success of Schmertmann's other more popular papers. Swell Sensitivity has great practical importance to practicing geotechnical engineers, one of the main themes of all of Schmertmann's work. In the current paper, the author reexamines Swell Sensitivity as defined and described by Schmertmann (1969) and illustrates the behavior for a number of expansive soils from around the U.S.
