<![CDATA[The Tanjung Langkat–Lautepu road section in Salapian District, Langkat Regency, serves as a primary access route supporting economic activities, education, and community mobility. Over time, due to increasing traffic volume and environmental factors, this road section has suffered various types of damage, resulting in reduced comfort and safety for road users. This study aims to assess the pavement damage level using the Indeks Kondisi Perkerasan (IKP) method, determine appropriate treatment based on road conditions, and calculate the Budget Plan (RAB) for road improvement works. The study covered a 4.7 km stretch, utilizing visual surveys on 100-meter segments. Analyses included Average Daily Traffic (ADT), Equivalent Standard Axle (ESA), pavement structure determination based on the 2024 Road Pavement Design Manual (MDPJ), and Budget Plan (RAB) preparation using the 2025 Standard Analysis of Work Prices (AHSP) and North Sumatra Province Unit Prices. Results using the Indeks Kondisi Perkerasan (IKP) method yielded an average IKP value of 57.3 falling into the "Fair" category. Consequently, a structural improvement treatment is recommended with the following layer specifications: Class B Granular Sub-base (LPA) = 15 cm, Class B Granular Sub-base (LPA) = 15 cm, Class A Granular Base (LFA) = 20 cm, AC-BC = 6.5 cm, and AC-WC = 4 cm. The required Budget Plan (RAB) is Rp15,022,408,570 (Fifteen billion twenty-two million four hundred eight thousand five hundred seventy rupiah).]]>
