Sultan Aji Muhammad Sulaiman Sepinggan (SAMS) Airport has an important role as the gateway of economic activity in Balikpapan, East Kalimantan. Elements of the airport consist of runways, taxiway, apron and the terminal building of departure and arrival. The runway has an important role as a key element in airport infrastructure, this is related to aircraft and passenger safety in air traffic at SAMS Airport, which is currently one of the best airports in Indonesia that meets the International Standard qualification. The purpose of this study is to perform visual assessment of runway deterioration at SAMS Airport using PCI (Pavement Condition Index) method, to know the factors affecting runway deterioration and the effective distress treatment to overcome deterioration at a runway. The visual assessment data are collected from PT. Angkasa Pura I (Persero) Sepinggan, by measuring the types and area of deterioration occurring on the runway during 1-month period (in September 2018), then PCI is analyzed by using ASTM D 5340 – 98. The results show that the PCI value is 80.4 which means the rating is excellent. The most common typical distress occurred at Threshold Runway 25 section 1 with the type of distress is block cracking which mainly caused by asphalt concrete shrinkage and daily temperature condition resulting in stress or strain series, another type is depression initially caused by the settlement from the soil foundation or construction process. Since PCI shows excellent state, the distress repair treatment to be performed is surface repair or routine maintenance with partial mill and overlay method.
