Abstract
This manuscript presents a comprehensive life cycle assessment (LCA) comparing asphalt and concrete pavements in terms of environmental impacts, economic costs, and performance parameters. The study evaluates the construction, maintenance, and end-of-life phases using data and engineering methodologies available up to the year 2020. Emphasis is placed on energy consumption, greenhouse gas emissions, durability, and recyclability. The assessment aims to provide a balanced and technically grounded comparison to assist decision-makers in infrastructure planning. Results indicate that while asphalt pavements generally have lower initial costs and energy demand, concrete pavements outperform in long-term durability and lifecycle greenhouse gas reduction under typical traffic conditions.
