This paper examines the use of recycled materials in pavement construction and how it may mitigate some civil engineering problems like environmental damage and resource depletion. The aim is to determine the technological, ecological, and economic appropriateness of integrating different types of waste materials into road construction. A literature study, along with an approach for incorporating circular economy concepts into pavement design and construction, serves as the basis of this analysis. Results show that the use of crushed concrete, RAP, crumb rubber, and plastic waste can supplant virgin materials, and in most cases, enhances the performance of pavements while lowering costs over the pavement’s lifetime. Performance assessment illustrates enhanced sustainability benchmarks when compared to traditional approaches. This research lays out detailed guidelines for incorporating reclaimed materials for sustainable economic and environmental outcomes in road infrastructure projects.
