Sustainability Assessment of Alternative Pavement Materials

The increasing demand for road infrastructure and the environmental impacts of traditional pavement materials such as asphalt and concrete have prompted the exploration of alternative materials for pavement construction. This study focuses on assessing the sustainability of various alternative pavement materials, including recycled asphalt, rubberized asphalt, permeable concrete, and geopolymer-based materials. The environmental, economic, and social impacts of these materials are evaluated in terms of life cycle assessment (LCA), durability, cost-effectiveness, and resource conservation. The results highlight the potential of these materials to reduce the carbon footprint, improve water management, and enhance overall sustainability in pavement construction. The research concludes that with optimized design, these alternative materials can offer a more sustainable solution for road infrastructure while addressing the challenges of resource depletion and environmental degradation
