Dowel bar retrofitting is a method used to restore or provide better load transfer across transverse joints or cracks using dowel bars Usually dowel bar retrofits are necessitated by excessive faulting due to a loss of aggregate interlock over time It is interesting to note that much of the rigid pavement built in the U S during the 1950s and later included dowel bars for load

Dowel bars are short steel bars that provide a mechanical connection between slabs without restricting horizontal joint movement They
Dowel bars are usually inserted at mid slab depth and coated with a bond breaking substance to prevent bonding to the PCC Thus the dowels help transfer load but allow adjacent slabs to expand and contract independent of one another Figure 3 shows typical dowel bar locations at a transverse construction joint Figure 2 Stainless steel clad dowel bars Epoxy Coating on
The purpose of dowel bar baskets is to transfer loads across a joint without restricting joint movement due to thermal contraction and expansion of the concrete To develop load transfer across a joint dowel bar baskets are placed at specified locations to assist with adequate load transfer from the pavement approach slab to the leave slab Dowel Bar Basket Specifications
