Co-evaluation d'enrobes chauds et tiedes, neufs et recycles a 30% : etude de la RD 93N

This article presents the result of an experimental worksite carried out in 2010 in the Drome region of France. The aim of the undertaking was to compare from the environmental viewpoint, and at the request of the General Council of Drome (CG 26), different technical solutions in connection with one of its pavement rebuilding contracts. The CG 26 wished in particular to be able to compare the effect of the saving of aggregate and bitumen resources by the use of an aggregate rate of 30% and the concomitant effect of a saving of energy by the use of warm-mix asphalt at a temperature of 110°C instead of hot-mix asphalt. This study included a technical phase upstream of the worksite and involving the aspahlt mix design and worksite follow-up, as wellas an environmental study relative to the initial construction of the pavements. The latter was geared toward eco-evaluation based on a methodology of life cycle analysis (LCA) and the performance of environmental measurements on the site of the mixing plant of the company Braja that carried out the work.
