The characterization of materials in laboratory follows standards. For the determination of the bearing ratio-CBR, the applicable standard provided a use of a maximum size of 20 mm diameter. But in practice, the laterite is compacted without removing coarse particles. The aim of this research is to get closer to the field realityby testing the materials with all the elements involved in road building layers. To do this, the laterite coming from Sindia quarry, used for many years in road construction in Senegal is studied. The geotechnical characterization focused on lateritic gravel samples from respective granular classes 0/20; 0/25; 0/31.5; 0/40 and 0/63 mm size. In interpreting the results of laboratory tests, the concept of optimal diameter (Dmax) occurred during the study in addition to the terms usually used as optimum water content and optimum dry density.
