Abstract

This study compares the performance of roads using recycled asphalt pavement (RAP) and conventional asphalt in supporting sustainable development. The research was conducted using a literature review and secondary data analysis from various laboratory test results and field projects in Indonesia. The findings indicate that asphalt mixtures with RAP content ranging from 30–50% can achieve Marshall stability equivalent to or even higher than conventional asphalt, with material cost savings of up to 35–40% per ton. Additionally, RAP significantly reduces the consumption of new aggregates, construction waste, and carbon emissions, thereby supporting the principles of green roads and resource efficiency. However, the use of high levels of RAP requires the addition of rejuvenating agents to maintain the flexibility and durability of the mixture. Therefore, optimising the use of RAP through proper proportioning, mixing technology, and supportive policies can serve as a strategic solution for environmentally friendly, efficient, and sustainable road infrastructure development in Indonesia.
