The present work aims to study the variability of the petrological and geotechnical properties of lateritic gravel developed under the same climate, the same vegetation, the same gneissic bedrock, but located under different hydric conditions, with a view to their use in road construction. The study was conducted on a rock quarry and 18 lateritic gravels quarries. After a detailed macroscopic description of the materials, the samples taken were the subject of petrological and geotechnical studies. The mineralogy of the powders of rock and lateritic gravels samples was determined by optical microscopy and X-ray diffractometry. The chemical determinations of the major elements of the materials were carried out by X-ray fluorescence and the de...
