Dowel bars are short steel bars that provide a mechanical connection between slabs without restricting horizontal joint movement. They increase load transfer efficiency by allowing the leave slab to assume some of the load prior to loading.
Dowel bar is a terminology used in CONCRETE pavements, in general. Dowel bars are round steel bars (not torr steel). The bars are placed between two CONCRETE slabs so that loads are transferred between the two slabs and any horizontal movement (due to expansion) is also allowed.
