In constructing the cast-in-place concrete track system, the installation of reinforcing bars to a TCL is one of the main causes of consuming construction time. In this study, to eliminate the reinforcing bar installation process, the applicability of the fiber reinforced concrete to the TCL is studied using the numerical analysis. The analysis is performed using the commercial finite element program, ABAQUS, and, in the analysis, the effect of the variations in fiber content rate and the surrounding temperature is considered. From the analysis, it is found that the fiber reinforced concrete has better applicability than the existing reinforced concrete with steel bar.
