Performance Evaluation of Carrying Capacity of Prestressed Bearers for Railway Turnouts Using Laboratory Experiments in Vietnam

Previous studies have addressed railway turnouts (switches and crossings), but research on the performance of 1000 mm gauge is limited. At present, wooden sleeper structures are used at in Vietnam. However, these many disadvantages operation process. This paper evaluates new prestressed bearer (PSB) for turnouts, designed gauge, to overcome a sleeper. Test samples PSB were manufactured factory, experiments conducted laboratory according European Standards evaluate carrying capacity. The test results show that proposed structure meets capacity under standard loads. In addition, static fatigue tests bearers considerable reserve cross-section means existing can be with larger locomotive axle, design optimized by arranging strands changing cross-section’s geometric dimensions. It hoped will viable alternative designing turnouts.
