Caractérisation des sols latéritiques utilisés en construction routière : cas de la région de l'Agneby (Côté d'Ivoire)

Abstract : The lateritic soils from the Agnéby region in Ivory Coast were studied using geotechnical data from geotechnical investigations for ten road sections built with lateritic gravelly soils in the road structure. The data consisted of particle size distributions, consistency limits of the fine particles, modified Proctor compaction tests and CBR tests. These data were analysed by classical statistical methods (characterisation of the variability of each parameter, correlation analysis of pairs of parameters) and by principal component factor analysis of all the data (188 samples). The study concluded that the lateritic soils samples had rather similar properties and could not be clearly differentiated by statistical analysis. The author suggests that his study should be enlarged to sufficiently big territories (a country or a part of Africa), which would contain all the types of lateritic soils mentioned in the literature, including forest laterites like the ones in Agnéby region, savannah laterites and laterites from ancient cuirasses. A methodology is proposed for this study. The thesis consists of six chapters, a general introduction and a general conclusion and an appendix with all the geotechnical data used.
