Evaluation of Road Conditions and Maintenance Cost Estimation for the Durenan-Prigi Section (Link 006) Using the Pavement Condition Index (PCI) Method

Abstract

The 30.4 km Durenan-Prigi road, managed by the East Java Provincial Government, serves as the primary route to key tourist attractions in Trenggalek Regency, including Prigi Beach and Mutiara Beach. To ensure user comfort and safety, maintaining the road's condition is essential. However, the road is prone to damage caused by factors such as heavy traffic loads, unstable soil conditions, extreme weather, and inadequate drainage systems. To comprehensively assess the road's condition, this study employs the Pavement Condition Index (PCI) method. The PCI method visually evaluates road damage by categorizing 20 types of damage into seven distinct categories based on severity and extent. The analysis revealed an average PCI value of 88.05 for the Durenan-Prigi road section, classifying it as "Perfect." Despite this classification, some sections require preventive maintenance to sustain optimal conditions. A detailed damage management plan has been developed, including patching, sealing cracks, and applying slurry seals. Patching is recommended for crocodile skin cracks, curling, vertical roadside cracks, longitudinal and transverse cracks, and localized depressions. Sealing is proposed for checkered cracks, while slurry seals are intended for addressing aggregate wear and granular disintegration. This study underscores the importance of routine maintenance to prolong the road’s lifespan and enhance its serviceability. By employing the PCI method, road condition assessments are made more accurate and systematic, enabling efficient allocation of maintenance resources. The findings highlight the significance of integrating drainage system improvements alongside regular inspections to prevent further deterioration, particularly during the rainy season.
