The utilization of Reclaimed Asphalt Pavement (RAP) in pavement construction presents a
promising avenue for sustainable infrastructure development. This study investigates the feasibility of
RAP materials, aligning with National Highway Authority (NHA) Class B specifications, through a
comprehensive analysis of physical and mechanical properties. Physical tests including sieve analysis and
abrasion testing, alongside mechanical assessments like penetration tests, inform the potential of RAP to
meet pavement construction requirements while reducing reliance on virgin materials. The rejuvenation
process, blending RAP bitumen with virgin bitumen, is optimized to balance mechanical properties and
sustainability objectives. Through optimized rejuvenation processes, blending RAP bitumen with virgin
bitumen achieves a 60/70 penetration grade, showcasing a reduction in virgin material usage and
enhancement in pavement durability. This approach highlights a qualitative shift towards eco-friendly
practices in pavement engineering, ensuring long-term environmental benefits while maintaining optimal
performance standards.
