“…For a given e o (the initial void ratio of the soil depends on the dry density and the initial water content), each symbol corresponds to a swelling test (when ∆e > 0) or a shrinkage test (when ∆e < 0). The data agree with the collected results; samples with low dry density (e 0 > 1) or high water content do not swell, and shrinkage is the main phenomenon that may impact these soils [49]. Conversely, the highly compacted materials do not shrink (or have low shrinkage) but also have a low swelling amplitude.…”

“…L'ampleur du gonflement (souvent appelé potentiel de gonflement) est reliée soit à l'augmentation de volume, soit à la contrainte engendrée par l'hydratation à volume constant. La notion de contrainte de gonflement a été l'objet de nombreuses discussions et les problèmes liés à sa détermination ne seront pas discutés en détail ici, mais brièvement illustrés (voir par exemple ASTM, 1985 ;IRSM, 1989 ;AFNOR, 1995 ;Serratrice et Soyez, 1996 ;Serratrice, 2007).…”

“…Dans les régions tempérées comme la région parisienne, la diminution de teneur en eau engendre une rétraction de l'éprouvette qui reste saturée jusqu'à la limite de retrait (AFNOR, 1997 ;Bigot et Zerhouni, 2000 ;Delage et Cui, 2000 ;Audiguier et al, 2007 ;Serratrice, 2007).…”
