L'étude de la faisabilité de l'utilisation des matériaux en stériles miniers dans les chaussées et les plates formes routières

Abstract

Mining generates significant deposits of waste rock, from both the mine and the ore upgrading processing plant. The valuation of these large volumes is proving very interesting from both an economic and environmental point of view. The objective of our work consists in the use of gravel and sands (waste rock) resulting from the mining of the mine of Kherzet Youcef, Ain Azel, Sétif and Kef Essnoun, Bir Later, Tébessa in public works sites. Consequently, these materials were introduced into the formulation of concrete (Sand 0/3) and asphalt (Gb and BB) and a series of conventional tests were carried out to control the quality of the final product. The results show that the correction of the formulations with these additions gave products with the performance required by the CPS of road construction sites for the pavement, wearing course and engineering structures. A detailed study and an explicit inventory of this frequently undeveloped substance is essential to inventory these new deposits of significant economic importance
