What Else Can Be Done?
Reduce shrinkage potential
– Improve concrete mix design
– Improve construction and curing techniques to reduce shrinkage potential
Restrain shrinkage?
– Steel design change: Looking into it! Stay tuned.
– 0-4893 Evaluation of Bonded Concrete Overlay on IH 610 in Houston, Texas, February 2008, Dongho Kim, Moon Won
• “…lack of continuous reinforcement near the bottom of the overlay (Item 4 on the list) and the use of concrete with high CTE (Item 1 on the list) are believed to be the primary contributing factors to delaminations.”
• “It appears that welded wire fabric provided more effective restraint on concrete volume change potential, thus helping better bonds between BCO and existing concrete.”
