Mechanical behaviors of structured soils can usually be quantitatively assessed based on the mechanical behaviors of the corresponding reconstituted clays. The method of preparing reconstituted soils will affect the quality of reconstituted samples remarkably, and therefore, affect their mechanical parameters. To guarantee the quality of reconstituted soil samples, a large diameter oedometer apparatus was modified for preparing reconstituted clay samples. To investigate the compression and strength behaviors of the reconstituted clay samples prepared by the modified apparatus, standard oedometer tests and triaxial undrained shear tests were also conducted. Odometer tests results suggest that the compression behavior of reconstituted clays is mainly influenced by initial water content for given clay. Triaxial undrained shear tests results show that the strength envelope is also influenced remarkably by initial water content for the reconstituted clays. Undrained shear strength can be well normalized by the normalized water content.
