CRACKS IN CONCRETE BRIDGE DECKS

A study of cracks in bridge decks as reported in the literature and observed in N.S.W. shows that certain types of cracks are predominant in particular bridge types. Cracks in composite bridges and in cast-in-place kerbs and cantilever deck slabs are shown to be largely due to the combination of temperature, shrinkage and traffic effects and may be controlled by increasing the amount of reinforcement. Cracks in bridges incorporating pretensioned units or constructed as voided slabs are apparently largely caused by settlement and can be corrected by appropriate construction procedures. This was also published as Sydney University School of Civil Engineers, Research Report No. R313 (see IRRD abstract no. 234329). (TRRL)
