REVÊTEMENT EN BÉTON BITUMINEUX D’UNE ROUTE NATIONALE

Abstract

The road plays a very important role on the transport between humans and the merchandise trade between the different national or international zones that is why the pavement must be properly established, so the rolling layer is the last layer A good layer allows a good circulation, the aim of this work is to study a rolling layer of bituminous concrete of a national road, in this study I The work of two parties: - the first part which reviews a generality on pavements and their degradation to fully understand the difficulties of a rolling layer after a definition of the materials concerned by this layer, bitumens and aggregates as well as bituminous mix. - The second experimental part, which reflects the practical work on a bituminous concrete layer, first with a laboratory-level study on all the tests on aggregates and bitumen and the asphalt mixtures for accepting the materials according to the standards before mixing, Analysis and results to conclude a good final and acceptable final formulation and finally the implementation of the bituminous concrete layer on a national highway. And conclusion to draw lessons on this research topic
