<![CDATA[Flexible pavement design is a critical aspect of road infrastructure development to ensure durability, safety, and efficiency, particularly in supporting rural connectivity in regions such as Karo Regency. This study aims to conduct a performance-based comparison of flexible pavement design for the Kutabangun–Kutakendit road section at STA 0+000 to STA 2+000 using the AASHTO 1993 method and the 2017 Revised Highways Pavement Design Manual. The analysis evaluates pavement layer thickness and structural configuration in relation to expected traffic loads and subgrade conditions. The results indicate that the 2017 Revised Highways method emphasizes a thicker base layer to enhance structural strength, while the AASHTO 1993 method distributes the load across multiple layers, including surface, base, and subbase, resulting in different structural compositions. These variations reflect differing design philosophies that influence pavement performance, cost efficiency, and construction feasibility. Therefore, selecting an appropriate design method requires consideration of local conditions, material availability, and long-term performance to achieve sustainable and reliable road infrastructure development.]]>
