Bridge Deck Drainage Guidelines
The 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, the document provides sound drainage design practice for bridge drainage. The document, plus HEC No. 12 and NCHRP Synthesis No. 67, provide very complete reference material for bridge drainage.
