The field plate load test a good potential for determining modulus since it measures both plate pressure and settlement. However, because The field plate load test is expensive and takes plenty of time for operation, it is very difficult to figure out the test characteristics of railroad roadbed in detail. For faster and economical operation, the Dynamic Cone Penetrometer(DCP) and the Light Falling Weight Deflectometer(LFWD) have been utilized for estimating the bearing capacity of railroad roadbed. The objective of this study is to determine the relationship between the test(PLT, DCP, LFWD) of the railroad roadbed in Korea. The DCP test and LFWD test for evauluating the strength of railroad roadbed materials produced in Korea are presented in this paper.
