Abstract:
This paper presents an attempt to use crushed quartzite as a substitute to crushed basalt, which is since more than sixty years the most systematically used aggregate on all the Senegalese territory to formulate the bituminous mixes for pavement. This massive use induced a decrease of basalt reserves and it is urgent to find other substitution materials. This article reports an attempt to valorize crushed massive quartzite from Bakel in the region of Tambacounda in Senegal. The studies carried out on a mixture of quartzite composed of 23% of 8/14, 25% of 3/8 and 52% of 0/4 and bitumen 35/50 showed that this quartzite material complies with the rules and practices currently in force in Senegal.
