단열재 사용에 의한 철도 자갈도상 동상방지 모형시험

초록

In this research, model test of ballast track in freeze chamber were carried out in order to study the method of preventing or reducing frost heaving. For the model test, XPS and PE gravel were used, In some cases, they were applied by mixing the two materials. From the result, it can be seen that insulation materials showed different effects according to the order and type of the materials. Therefore, the test results can be used as a good reference for the practical application in field test.
