EVALUASI KINERJA PERKERASAN KAKU (RIGID PAVEMENT) BERBASIS BETON (STUDI KASUS PADA JALAN AKSES TPA SUKAWINATAN)

Abstract

The access road to the Sukawinatan Final Disposal Site (TPA) is a strategic infrastructure in the waste transportation system of Palembang City, but it experiences high pressure from heavy vehicles, especially fully loaded garbage trucks. This study aims to evaluate the performance of concrete-based rigid pavement using the Pavement Condition Index (PCI) method based on visual surveys, average daily traffic analysis (LHR), and identification of the type and extent of damage per segment. The results showed that the direction of loaded vehicles recorded an average PCI of 70.3 (Fair–Satisfactory), while the direction of empty vehicles reached 88.2 (Satisfactory–Good). The dominant damage included transverse elongated cracks, minor crocodile skin cracks, and local landslides, triggered by repeated axis loads, the absence of drainage systems, and leachate infiltration from operational trucks. Analysis of the relationship between variables indicates that load pressures and extreme environments accelerate the decline in structural performance, especially in the STA 100–150 priority segment. Technical recommendations include localized overlays, subgrade reinforcement, drainage construction along the sections, and periodic maintenance based on PCI classifications. This study provides a basis for planning for more effective and sustainable road maintenance to support the smooth operation of the Sukawinatan Landfill.
