Abstract

Road infrastructure deterioration is a critical challenge for regional road authorities in Indonesia. This study applies the Surface Distress Index (SDI) method through a systematic visual survey to assess the structural pavement condition of a 4,500-meter section of Deandels Road in Probolinggo Regency, East Java, covering 45 segments of 100 meters each. SDI scores were computed by evaluating crack area, crack width, pothole count, and rutting depth per segment. Results show that 66.7% of segments are in Good condition (SDI < 50), 8.9% Fair, 22.2% Light Damage, and 2.2% Severe Damage. The most critical failure was identified at STA 2+900–3+000 (SDI = 155), requiring full reconstruction. A maintenance priority framework yields a total estimated cost of IDR 937,284,642.47. The SDI method proved effective as a practical, low-cost tool for pavement management in resource-constrained regional road authorities
