Fabien Peltier, Chef d'établissement chez Colas.
Un marché expérimental mené avec un conseil départemental a permis de réaliser un chantier routier à faible impact carbone. Routes élargies en béton recyclé et chaussée en enrobé 100 % recyclé ont été produites localement, avec pour seuls apports le liant et le bitume, garantissant performance technique, économie et durabilité.
An experimental project with a local authority delivered a low-carbon road scheme. Widened roads used recycled concrete and 100% recycled asphalt, produced locally. Only binder and bitumen were added, ensuring technical performance, economic efficiency, and strong environmental benefits through short supply chains and material reuse on the construction site itself.
