  Recently, there is a concern about rebar corrosion of concrete track slabs. Hence durable concrete track slabs have been heavily required in the railway transport field. To comply with this requirement, the authors have suggested applying the sort fiber reinforce concrete without rebar to the concrete track slabs. In order to confirm the effectiveness of the suggestion, the influence which the kind and the amount of mixing of the fiber give on fresh properties and the bend toughness of concrete was examined. Furthermore, experiment and calculation about the bend fatigue were conducted. According to these results, the calculation conformed to the experiment result, and the destruction behavior was able to the expressed.
