Permanent deformation parameters of fine – grained tropical soils
In this work, the permanent deformation response of fine-grained soils of different classifications was studied through repeated load triaxial tests under different stress states for a number of load cycles greater than 150.000. Soils were moulded at optimum water content compressed with an amount of energy equivalent to intermediate or normal Proctor. Seven fine-grained soils were selected with the following MCT (Miniature, Compacted, Tropical) classifications: four lateritic clayey, one lateritic sandy, one non lateritic sand and one non lateritic silt. The values of total permanent deformation are presented. The parameters of deformability Ψi were estimated. The permanent deformation calculations were simulated for three different stress levels: low, medium and high.
