Sustainable Management of Construction and Demolition Waste: Utilizing Recycled Aggregates for Road Construction in Lebanon and Tunisia

This article delves into the growing significance of managing construction and demolition waste (CDW) in Lebanon and Tunisia, with a specific focus on the utilization of recycled aggregates for road construction. It outlines the challenges posed by CDW management and explores the potential of recycling and reusing materials to mitigate these challenges.

The authors highlight the benefits of recycling CDW, including the preservation of natural resources, reduction of illegal waste disposal, and alleviation of land use pressure. Through a comprehensive review of tests conducted on recycled aggregates from both countries, the article demonstrates the feasibility of incorporating recycled materials into various road construction applications.

Key findings indicate that recycled aggregates possess favorable mechanical and environmental properties, making them suitable substitutes for natural aggregates in road construction. The article underscores the importance of waste management optimization and the consideration of transportation in sustainability assessments to minimize environmental impact.

In conclusion, the article emphasizes the potential of recycled aggregates to advance sustainable infrastructure development in Lebanon and Tunisia. It calls for continued research and optimization of waste management processes to foster more environmentally friendly construction practices in the region.
