spacing between transverse joints is typically about 15 feet for slabs 7-12 inches thick. jointed reinforced concrete pavements (jrcp) contain steel mesh reinforcement (sometimes called distributed steel). in jrcp, designers intentionally increase the joint spacing and include reinforcing steel to hold together mid-panel cracks.
