The development of several cracks on reinforced concrete bridge decks is a serious, growing problem that not only affects the state of Ohio, but also the United States as a whole. Many bridge decks constructed within the last 10 years in Ohio have already shown varying levels and patterns of cracking. Regardless of the bridge design type, length of the spans, deck thickness, and concrete mixture designs, cracks will develop on reinforced concrete bridge decks. Bridge deck cracking is a critical issue because cracks allow harmful and corrosive chemicals to penetrate the concrete and deteriorate the reinforcing steel that is embedded in the concrete. If proper precautions and steps are not taken, then this could lead to rapid deterioration leading to costly maintenance problems and need for possible replacement. The Ohio Department of Transportation’s current bridge inspection procedure requires periodic inspections of the whole bridge. ODOT’s inspection procedure only offers a qualitative assessment of the bridge and does not give a quantitative measurement of the bridge deck cracking. The primary objective of this report was to evaluate the cracking performance of structural slab bridge decks and compare with that of bridges constructed with stinger supports in the ODOT’s District 3. Extensive crack surveys were completed for six bridge decks, three structural slab supported bridges and three stinger supported bridges. Crack densities were then determined based on the crack maps corresponding to the surveys for each bridge deck. These crack densities revealed that the structural slab supported bridge decks had a higher propensity for cracking than the bridge decks constructed using stringer supports. Also, since the six bridges surveyed have been constructed within the last two years, a definitive relationship between the age of the bridge and the cracking performance of the bridge deck is not yet evident.
