DESIGN AND CONSTRUCTION OF CONVENTIONAL BRIDGE DECKS THAT ARE RESISTANT TO SPALLING

An analysis was made to determine the length of time until spalling (induced by reinforcing steel corrosion) occurs and the relative cost for different conventional concrete bridge deck designs. Research results of others provided the data from which the time to corrosion was estimated. Three factors were considered: (a) frequency and rate of deicing salt application, (b) water-cement ratio of concrete, and (c) depth of concrete cover over reinforcing. The latter two were variables in deck design and construction. Decks with two combinations of water-cement ratio and clear cover each for two bridges were designed. From these, cost differences for labor and materials were determined. It was concluded that in Kansas conventional decks can be protected from spalling for a 50-year period. Also, life can be tipled for only a 2 percent cost increase by switching from decks with a 5-cm (2-in.) cover and a water-cement ratio of 0.44 to decks with a 7.5-cm (3-in.) cover and a water-cement ratio of 0.35. /Author/
