摘　　要：The main objective of this paper is to study the mechanical properties of a material formulated in the laboratory which is a GS （gravel slag） based on crushed aggregates treated with metallurgical waste which is the blast furnace slag. The authors show in particular, as a road application, the treatment of gravel slag provides mechanical properties allowing its use in road construction. We will introduce different contents of slag （10%, 15%, 20%, 25% and 30%） and test the mechanical properties of the mixtures obtained through CBR Punching tests, simple compression test and tensile test. This work is in the context of the valorization of blast furnace slag, which is found in large quantities as waste dumps that came to disturb the environment.
