The objective of this study is to confirm the field application of coarse aggregates technology mixtured with high strength mortar under the rail. In the present study, the field tests are performed to find the field state and aggregate gradations and the laboratory tests are performed to find the compressive strength of the pre packed concrete cylinder specimens and the core specimens obtained at the field.
