Abstract:
In 1992, the National Cooperative Highway Research Program (NCHRP) initiated a project to research transverse cracking of newly constructed and recently replaced concrete bridge decks. The objectives of this project were to determine the major factors, or combination of factors, that contribute to early transverse deck cracking and to develop specific recommendations to prevent or minimize such cracking. The research was limited to conventionally reinforced bridge decks constructed on both simple and continuous span superstructures. The project includes laboratory and field testing and computer analysis of various structural systems. The results of a survey of transportation department, and discussion of the problem and factors causing cracking are presented here.
