Abstract

The condition of road pavement that continues to experience degradation due to traffic loads and environmental factors requires regular evaluation to determine appropriate maintenance priorities. This study aims to evaluate the pavement condition of Jalan Guru Bangkol, Mataram City, using the Surface Distress Index (SDI) method as a basis for determining road maintenance priorities. The study used a descriptive quantitative approach through a visual survey of the road surface condition. The 1.25 km road section was divided into 13 observation segments with 100-meter intervals. Primary data were obtained through direct observation of the parameters of crack area, crack width, number of potholes, and wheel groove depth (rutting), then analyzed based on the SDI guidelines of the Directorate General of Highways. The results showed that of the 13 observed segments, 10 segments (76.92%) were in good condition, 1 segment (7.69%) was in moderate condition, and 2 segments (15.39%) were in a condition of slight damage, while no segments were found with severe damage. Based on the SDI value classification, most road sections are recommended for routine maintenance, while one segment requires periodic maintenance and two segments require road rehabilitation. The research results show that the SDI method is able to provide a systematic evaluation of pavement conditions and supports the determination of more objective and effective maintenance priorities as a basis for decision making in urban road infrastructure management.
