Tarakan City has several road segments on provincial roads that have experienced significant damage in the form of sinkholes and substantial potholes on the road surface. These deteriorations are primarily attributed to the impact of traffic, excessive traffic loads, subgrade soil conditions that fall short of requirements, and the use of pavement materials that do not meet the specified standards. To devise effective road repair plans, the collection of field data is crucial. Two distinct methods are employed for data collection to assess pavement conditions: the International Roughness Index (IRI) and the Surface Distress Index (SDI). The IRI method measures road roughness using the Rough meter III instrument, while the SDI method focuses on parameters like crack area, crack width, pothole count, and wheel path rut depth. The surveyed road sections encompass Amal Lama, Gunung Selatan, Aji Iskandar, Bhayangkara, Aki Pingka, and the Ring Road of Tarakan City. Research findings reveal the surface damage level of roads in Tarakan City using the SDI and IRI methods, with the following breakdown: roads in good condition account for 42.86%, those in moderate condition make up 51.90%, slightly damaged roads constitute 4.8%, and heavily damaged roads represent 0.44%. Additionally, the study has determined the percentage of each type of maintenance required: Routine Maintenance at 94.77%, Periodic Maintenance at 4.8%, and Reconstruction at 0.44%.
