This is mostly due to the bad proportion in binding agent and sometimes to an overex- ploitation of the piece of work. The present study enters within the general context of the re- search of alternative solutions for an efficient exploitation of local materials (gravelly) in road technique in Benin. This work has consisted to do two borrowing in each one of two zones on which a complete identification has been realized. The materials had afterwards ameliorated at 2%, 3% and 4% of cement in sight of the determination of optimal dose in cement which guarantees satisfactory mechanic characteristics. Accorded to this approach, it was deter- mined that the using of these materials at the natural condition is possible only in sub base course. The formulation study of heterogeneous gravelly-cement in base course has revealed optimal dose relative to every borrowing. Therefore, for security reasons depended on loss of yard, all these values have been brought back at 3.5% at the implementing of gravelly-cement within study zones. The application of this study will guarantee then relative economy no less important.Статья посвящена исследованию альтернативных решений по эффективной экс- плуатации местных материалов, в частности, гравийно-цементной смеси в технологии дорожного строительства Северного Бенина.gravelly lateriticroadpavementsmechanic characteristicsдорогатротуаргравиймеханические характеристики1.Valeurs de reference des caracteristiques des graveleux-ciment.
