Jointed Plain Concrete Pavement (JPCP)
Jointed plain concrete pavements (JPCP) contain enough joints to control the location all of the expected natural cracks. The concrete cracks at the joints and not elsewhere in the slabs. Jointed plain pavements do not contain any steel reinforcement. However, there may be smooth steel bars at transverse joints and deformed steel bars at longitudinal joints. Today, a majority of the U.S. state agencies build jointed plain pavements.
