ABSTRACT
The degradation of roads network in tropical countries is a major concerned nowadays. Many analysis link this problem to the specific environment of roads in their areas, but also to the limited knowledge on the real behavior of lateritic soils, mainly used for these roads construction and maintenance. To understand more this problematic in order to develop an appropriate and simple methodology of road control, we led a study to characterize laterites from Burkina Faso in a laboratory by using the penetrometer PANDA. This article presents the process of calibration of the lateritic soils and the different results obtained through this investigation.
