Sustainable Pavement Construction: A Comprehensive Review on the Use of Recycled Materials and their Impact on Performance

Abstract

The increasing demand for sustainable and environmentally friendly solutions in the construction industry has led to the exploration of using recycled materials in pavement construction. This study reviews the effectiveness of various recycled materials, including recycled concrete aggregates (RCA), coarse recycled aggregates (CRA), rubberized materials, fibers, recovered asphalt pavement (RAP), jarosite, fly ash, and ground granulated blast-furnace slag (GGBS), as potential substitutes for conventional materials. The mechanical properties, durability, and environmental benefits of these materials are assessed in the context of pavement construction. Although the appropriate percentage and treatment of recycled materials must be carefully considered, this review highlights the potential for recycled materials to contribute to sustainable pavement construction without compromising performance. By optimizing the mixtures and developing guidelines for their implementation, the construction industry can promote sustainability, reduce waste, and minimize the environmental impact of pavement construction
