Abstract
This paper, authored by J.P. Christory and G. Bonnet from the French Public Works Ministry, highlights the advancements in multifunctional concrete pavements within urban settings, particularly in France. As urban populations demand better quality of life, including reduced noise, pollution, and improved safety, the traditional role of pavements extends beyond mere durability and cost-efficiency. This paper explores the shift towards pavements that also offer aesthetic value, noise reduction, and enhanced environmental performance. The concept of Porous Urban Pavements (PUPs) is introduced as a response to these expanded roles, integrating functions like water management, noise attenuation, and improved safety through innovative material compositions and designs. These pavements are classified based on their multifunctionality, showing varied applications in urban environments to address specific disturbances like noise, water pollution, and traffic safety. Regulatory frameworks, such as the French Noise Law and water management regulations, support the development and implementation of such pavements, reflecting a broader commitment to environmental and quality of life improvements in urban planning. The paper discusses the technical, regulatory, and societal factors driving the adoption of multifunction pavements, including detailed examples of their application in French urban projects. It concludes that the multifunction pavement approach is becoming a necessity in urban development, aligning with broader objectives of sustainability, environmental stewardship, and improved urban living conditions.
