Use of Synthetic Pads on Railroad Tracks in Indonesia

Abstract

The performance, safety, and longevity of railway infrastructure in Indonesia are critical for national connectivity and logistics. Track components are continuously subjected to high dynamic loads, heavy axle weights, and challenging tropical environmental conditions, leading to material fatigue and degradation. Synthetic rail pads, placed as an interface between the rail and the sleeper, are a crucial component for mitigating these stresses. This research investigates the application and effectiveness of synthetic pads on Indonesian railroad tracks. The study analyzes the function of these pads in enhancing track elasticity, ensuring proper load distribution, and attenuating shock and vibration. A comparative analysis, supported by field data and laboratory testing based on national railway standards, is conducted to evaluate the performance of different synthetic materials (e.g., EVA, HDPE, rubber) used in the Indonesian network. Key performance metrics include vibration damping capacity, resistance to abrasion, and material durability under local climatic conditions. The results confirm that the implementation of synthetic pads significantly reduces impact forces, minimizes sleeper wear and abrasion, and improves overall track stability. This research concludes that the appropriate selection and use of synthetic pads are essential for extending the service life of track components, reducing maintenance cycles, and lowering the long-term life-cycle cost of railway operations in Indonesia.
