Amandine Terreux, ingénieure des Mines d’Alès et directrice technique adjointe chez Colas Territoires Île-de-France Normandie, décrit l’évolution de l’innovation routière. Autrefois centrée sur la performance technique des produits, elle s’oriente désormais vers des enjeux sociétaux et environnementaux : mobilité, sécurité, confort des usagers et conditions de travail. L’innovation répond à la transformation des attentes des collectivités et des citoyens. Chez Colas, elle intègre aussi la lutte contre les îlots de chaleur urbains et la réduction du bruit. Le service technique accompagne les projets publics et privés en proposant des solutions adaptées ou alternatives, visant à améliorer la durabilité et la qualité des infrastructures. L’innovation est essentielle à la compétitivité et à la pérennité de l’entreprise, soutenue par un laboratoire qui collabore avec les équipes de terrain pour optimiser les aspects mécaniques, chimiques et écologiques des travaux. Elle incarne ainsi une démarche de progrès continu.
Amandine Terreux, engineer from Mines d’Alès and Deputy Technical Director at Colas Territoires Île-de-France Normandie, explains how road innovation has evolved. Once focused on product performance, it now addresses broader social and environmental challenges—mobility, safety, user comfort, and workers’ well-being. Innovation reflects shifting expectations from authorities and citizens, emphasizing sustainable and livable urban environments. Colas integrates issues such as noise reduction and mitigation of urban heat islands. The technical department supports public and private projects, offering tailored or alternative solutions to enhance design and performance. Innovation is vital for competitiveness and longevity, enabling the company to enter new markets and meet emerging needs. Supported by an in-house laboratory, Colas teams collaborate closely to improve materials and processes from mechanical, chemical, and environmental perspectives. Road innovation thus becomes a driver of continuous improvement, sustainability, and responsible infrastructure development.
