have positive impacts on accessibility and mobility for local communities. (Ding et al., 2016) highlighted that the cost savings associated with using RCA can enable the construction of more extensive and better-quality road networks, improving connectivity and accessibility to essential services, employment opportunities, and social amenities. In addition to economic and accessibility benefits, the use of RCA in pavement construction can also contribute to improved community perceptions and aesthetics. (Braga et al., 2017) found that the reduced noise levels and smoother ride quality of RCA-based pavements were perceived favorably by residents, enhancing the overall user experience and livability of the affected neighborhoods. Furthermore, the environmental benefits of RCA, such as reduced resource extraction and waste diversion, can have indirect positive impacts on community well-being. (Huang et al., 2018) noted that the improved sustainability of pavement infrastructure through the use of RCA can lead to enhanced public health and quality of life, as well as foster a sense of environmental stewardship within the community. 10. Conclusion The use of recycled concrete aggregates (RCA) in pavement construction has emerged as a promising sustainable solution. Research has demonstrated the technical viability of RCA, with performance characteristics comparable or even superior to conventional aggregates. RCA also offers economic benefits, with lower material and life-cycle costs compared to natural aggregates. Environmentally, the utilization of RCA contributes to resource conservation, waste diversion, and reduced greenhouse gas emissions. The positive social and community impacts, such as job creation and improved infrastructure accessibility, further strengthen the case for widespread RCA adoption. To ensure successful implementation, a holistic approach is required, addressing technical, economic, environmental, and social considerations. Continued research, harmonized standards, effective stakeholder engagement, and the promotion of circular economy principles are crucial to realizing the full potential of RCA in pavement applications. By embracing this sustainable material, the construction industry can move towards a more environmentally, economically, and socially responsible future for transportation infrastructure.
