If slabs are put on high quality subbases with consistent support and consist of low shrinkage concrete with joints correctly installed with spacings of 15 feet or less, reinforcement is generally unneeded. Most likely, there will be few random or out-of-joint splitting. If random fractures do happen, they must stay fairly tight because of the limited joint spacing and low concrete shrinkage consequently restricting future serviceability or maintenance concerns.
