레일패드 소재의 물리적 특성에 관한 비교 연구

In this study, we investigate the mechanical properties of rail pad material according to pad types. Especially, to study the application and endurance of TEEE material, we conducted experiments such as tension strength test, hardness test, fatigue test and wear test. Test results showed that TEEE material was better application and endurance than other pad material, but there was difficulties for comparing with others because the variations of application according to pad' types were variable.
