This research was conducted to analyze the behavior of the post-tensioned concrete pavement (PTCP) system in which weigh-in-motion (WIM) sensors were installed. One lane of PTCP was constructed after removing the existing asphalt pavement. The frictional resistance between the slab and the underlying layer should be small enough for the PTCP slab to properly have prestresses by tensioning. By performing an experimental construction of PTCP, the friction effects and the longitudinal displacements of PTCP under environmental loads were investigated. Based on the knowledge obtained from the experiments, the actual PTCP sections including WIM sensors were constructed and the curling behavior of the system was investigated. As a result, the behavior of the PTCP system was not affected by the existence of WIM sensors, and the appropriate PTCP system when installing WIM sensors in it could be developed.
