download PDFAbstract. Growing concerns about environmental sustainability and increasingly restrictive waste management regulations have led to the use of construction and demolition wastes (CDWs) as recycled aggregates for civil engineering projects, such as construction and infrastructure development. In this context, this paper presents an experimental laboratory analysis of the technical and environmental properties of recycled aggregates obtained from selected CDWs, conforming to European standards. The technical evaluation encompassed composition tests, particle size distribution (granulometry), density, water absorption, shape, the Los Angeles test, and the Micro-Deval test. The environmental assessment focused on the presence of potential contaminants, such as PAHs (polycyclic aromatic hydrocarbons), PCBs (polychlorinated biphenyls), and BTEX (benzene, toluene, ethylbenzene, and xylene). The laboratory test results are discussed and compared with current requirements. The paper concludes with key findings and recommendations derived from this investigation.
