Evaluasi Kondisi Jembatan Kereta Api Bentang Tunggal

Abstract

Degradation of railway bridge are influenced by aging, operational load, and environmental condition. Routine inspections on bridge are very important to give the information about existing condition. Limited of maintenance funding is the reason to rank bridge maintenance program or priority. PT KAI uses the Manajemen Perawatan Jembatan (MPJ, 1993) as bridge inspection procedure. The information however is in qualitative manner, which cannot justify the rank, so maintenance program is ineffective. Index condition model is one of alternative to resolve the problem, which can be used to rank the bridge structures or its components. The research carried out show index of 95.18 (very good) for BH (Bangunan Hikmat) 641 and index of 88.38 (very good) for BH 577. However condition of railroads for both of the bridges have index of 39.71(bad), thus need to be prioritized in maintenance program
