Road construction and maintenance impact directly users and resident activity. Typically, impacts are pollution, reduced road usage, depletion of resources, noise Within the framework of its mission to promote innovationand development in road methodologies, Setra, the technical department ofthe French Ministry for Equipment, is monitoring two modern techniques minimizing some of these impacts: pavement cold recycling, in situ or in theplant, and warm mix asphalts. Studies on these techniques show different states of progress. Cold recycling is in a final stage, whereas warm mix asphalts are still in an intermediate stage. A survey on the knowledge, practices and concerns of all players took into account the points of view ofproject owners, contractors, and users. It shows that creating an appropriate analysis base provides useful elements of reflection. This article examines potential orientations and supporting action required for developing the use of these techniques. For the covering abstract see ITRD E139491.
