Review Article on Use of Recycled Materials in High-Performance Concrete for Construction Work

Abstract

Demand for sustainable practices in road construction has been fuelled by the growing scarcity of natural resources and increasing environmental concerns. To that end, significant attention to recycled materials such as Reclaimed Asphalt Pavement (RAP), Construction and Demolition (C&D) waste, Tire-Derived Aggregates (TDA), and plastic waste has provided a potential solution that arrests environmental degradation but reduces economic costs as well. This paper reviews some case studies on the application of recycled material in road construction from different countries around the world, assessing their efficacy, advantages, problems encountered, and long-term sustainability. Technical issues related to material compatibility, mix design, and quality controls are also investigated.
