Dowel and Tie Bars

Dowel bars must be installed in the transverse joints, and tie bars in the longitudinal joints of concrete pavements in order to prevent the outward movement of the slabs in accordance with the German Guideline ZTV BetonStB for load transfer and assurance of equal height of the slabs.

Traffic and weather influences may result in damage. Cracks in concrete vehicular-use surfaces may be repaired by the subsequent installation of dowels and ties.

Fields of application

  • To remedy dynamic movement at concrete joints and cracks due to lack of, or ineffective load transfer, dowels and tie bars at joints must be installed.
  • Retrofitting of dowels and ties in emergency lanes showing defective connection to the adjacent concrete lanes.
