Abstract
This paper presents the results of the study of the physical and geotechnical properties of the vertical profile of lateritic soils. The study analyses the different zones of the profile. The study of the physical-mechanical properties is carried out according to the unified soil classification system. The mineralogical composition is determined by DRx and the chemical composition by ICP-AES. Among the physical properties analysed are particle size distribution, specific weight of solid particles, dry density and porosity, pore index, moisture and degree of saturation, plasticity, angle of internal friction and cohesion. The upper ferricretic layer is characterized by a sandy-gravelly grain size, whilst in the limonitic, transition and saprolitic zones the silt-clay fraction predominates.
