Towards Sustainable Road Pavement Construction: A Material Passport Framework

Sustainable transport infrastructure, highlighted in Agenda 21, Rio+20, and the 2030 Agenda, promotes resource efficiency and reduced environmental impact. Integrating circular economy principles into road construction supports these goals. However, limited material traceability and insufficient lifecycle information hinder the effective adoption of circular practices in the sector. Material passports have emerged as an enabling tool to address this gap by systematically documenting detailed data on material composition, environmental impact, lifecycle history, and potential for reuse or recycling. Despite growing adoption in the building sector, their application in road infrastructure remains limited. Therefore, this study aims to develop a material passport framework tailored for road pavements to enhance circularity and promote sustainable material management. A two-phase research method was used; first, a structured desk review identified relevant attributes; second, these attributes were categorized into six key domains and organized across three hierarchical levels: product, layer, and material to reflect pavement system complexity. The proposed framework enables multi-level documentation. Thus, the outcome of this study majorly contributes to advancing circular economy practices and the achievement of sustainable development goals by promoting resource efficiency, sustainable infrastructure, and responsible material use across the pavement lifecycle.
