Caltrans rigid pavements are plain jointed concrete, except for several experimental sections. They have no dowels at the transverse joints except for a few pavement sections built since 1999. Caltrans did not use dowels in the 1950s and 1960s when most California rigid pavements were built because of the inability of construction

Expansion joints are usually a complete 'gap' between adjacent bays, ie, there is a definite break in the concrete and any reinforcing steel that may be present. Where adjacent bays are 'tied' together by means of dowel bars, these dowels are sleeved in one of the bays to allow expansion to take place without generating stresses within the slab.

All types of joints are used in rigid pavement construction methods for all PCC pavement types. CRCP uses longitudinal reinforcing steel in order to limit the number of transverse contraction joints, but it still uses longitudinal joints and periodic transverse joints. Joints can be formed in two ways. Contraction joints are most often sawed in after PCC placement. Others such as expansion ...

Dowel bars are provided at the transverse contraction joints to provide load transfer, which reduces deflections and stresses due to wheel load appliions. To allow the slabs to move freely in the longitudinal direction due to temperature and moisture variations while providing efficient load transfer, dowel bars are lubried at least onehalf of their length.

 · Dowel bars. Dowel bars are steel bars, generally round in shape, and are used in the expansion joints which, are provided in the concrete pavements (rigid pavements) to allow the expansion of the concrete slab. The main function of the dowel bars is to transfer the wheel load from one slab to the adjacent slab through the shear and bending moment.
