Abstract:

Bridge deck design, at present, often includes costly bridge deck drainage provisions. Many bridge engineers have questioned the need for bridge deck drainage appurtenances, at least to the extent presently included in typical bridge design. This document presents criteria to determine if bridge drainage scuppers and drains are required. A design nomograph allows a rapid decision to be made. A key variable, design rain intensity, is analyzed: the rational method is reviewed and new methods for setting design rain intensity are presented that consider hydroplaning and driver vision. Regardless of the need for scupper, bridge end drainage is necessary, and methods are given. If scuppers are needed, this document provides sound drainage design practice for bridge drainage. This document, plus HEC No 12 and NCHRP synthesis No 67 provide very complete reference material for bridge drainage. Good engineering judgment is still a factor for locating scuppers. For example, if theoretical scupper spacing is 150 ft and piers are 100 ft apart, the scupper spacing should be set at 100 ft to accommodate vertical downpipes and provide adequate support.
