Abstract: A in earthbeaten road meeting the requirements of the standards in force to meet the operating conditions according to the traffic constraints relating thereto; requires the mastery of the geotechnical parameters of the road. In this article, we have identified the geotechnical parameters of the Lubumbashi - Kasomeno road, particularly from the Kasenga road junction, subdivided into several sections for a good efficiency of the studies made. Since the geotechnical parameters found in the laboratory were low, to improve the soil quality and to have a good lift of the road, we considered the contribution of the good quality material to mix with the platform of the road by compaction. In order to minimize the cost of work, we suggested that the filler material be pulled in the vicinity of the road.
