Sustainable Pavement Materials Using Recycled Plastics And Industrial Byproducts

Abstract

This paper analyzes how the incorporation of recycled plastic and reclaimed industrial materials as fillers in sustainable pavement mixes impacts the performance of the road infrastructure and alleviates environmental issues. The goal is to determine the value of engineering benefits in comparison to their mechanical properties, evaluating environmental impacts. The methodology entails reviewing comprehensive library resources published from 2000 to 2021 regarding material types, methods of processing, and performance metrics. Results confirm the presence of these waste materials enhances pavement life as well as rutting and fatigue resistance while diminishing the use of virgin materials and landfill space. Some issues related to compatibility of materials and long-term effectiveness are stated as concerns. This research highlights the importance of waste valorization in the construction and civil engineering fields and the creation of sustainable pavements for a circular economy.
