Deterioration Rates of Minnesota Concrete Bridge Decks

Deterioration Rates of Minnesota Concrete Bridge DecksStatus:  Complete
Report Date:  11/03/2014


Researchers analyzed several decades of bridge deck condition data to determine how quickly bridge decks deteriorate in Minnesota. This information will aid MnDOT's long-term planning for rehabilitation and replacement activities, and will help provide data-driven information for making funding decisions for these projects. Bridge decks were found to deteriorate from excellent to good condition faster than previously expected, but deterioration from good to fair or poor condition was found to be slower than originally thought.
