Abstract

Concrete bridge decks are exposed to some of the harshest weather, that any structural element experience. Regular concrete slabs that rest on earth, are exposed to the same environmental effects, but they also have the ground to help heat them in extreme winter. Bridge decks are surrounded by cold air. This cold environment cause transportation department to cover concrete bridge decks with deicing salts to dissolve ice present on the decks. These deicing salts cause major problems with reinforced concrete. Cracking of concrete bridge decks impose even larger problems, because the cracks allow the chlorides from deicing salts to infiltrate the concrete. It is impossible to totally eliminate the cracks in concrete, so designers try to minimize the crack widths. This paper deals with the control of cracks in a concrete slab that has been reinforced with glass fiber reinforced polymers.
