<p>The present study investigates the stabilization of subgrade pavement materials by incorporating fine reclaimed asphalt pavement material (RAPM) in varying proportions. By analysing four soil types with varying plasticity and correlating RAPM content with both CBR and MR values, the research contributes novel data to support sustainable and region-specific pavement design practices. With increasing urbanization and road infrastructure development, the sustainable utilization of RAPM in pavement design has gained significant attention. However, the lack of comprehensive laboratory data limits its widespread application. This research addresses the issue by examining four distinct subgrade soil types, sourced from Mysore and Chamarajanagara districts in Karnataka, India, blended with RAPM in proportions ranging from 5 to 25% by dry soil weight. The study evaluates the impact of RAPM on the soaked California Bearing Ratio (CBR) and resilient modulus (MR) using standardized geotechnical testing methods. Results indicate that the inclusion of RAPM enhances the mechanical properties of subgrade soils, with notable improvements in MR and CBR values, particularly in soils with lower plasticity. A near-linear relationship between RAPM content and both CBR and MR values suggests its viability for subgrade stabilization, leading to improved load-bearing capacity and long-term pavement performance. The findings contribute valuable data to pavement engineering, supporting the integration of RAPM in mechanistic-empirical pavement design. Future research should explore the field performance of RAPM-stabilized soils under varying climatic and traffic conditions to further validate laboratory findings and optimize material blending ratios for enhanced durability and sustainability in road construction.</p>
