Evaluation of Performance of the Railroad Roadbed Material by Model Fatigue lest

실내 모형반복실험에 의한 철도노반재료의 성능 평가

Dynamic fatigue test is carried out using soil model box for the evaluation of performance of three different roadbed materials. Bearing capacity, settlement and mud pumping phenomenon of each roadbed materials as well as penetration of model ballast into the roadbeds are investigated. It was found that settlement of slag and crushed stone roadbed is smaller than the soil roadbed during dynamic fatigue test with same initial conditions.
