Abstract:
The manual provides guidelines and procedures for designing bridge deck drainage systems, inclusing illustrative examples. Should the design process indicate a drainage system is needed, utilization of the most hydraulically efficient and maintenance-free system is emphasized. The manual also stresses the advantages of designing to minimize the complexity of bridge deck drainage systems. Integration of practical drainage details into overall structural design is presented. For user's convenience, all design graphs and nomographs appear in the index. The manual is a compendium of bridge drainage design guidance. It includes design theory, step-by-step design procedures, and illustrative examples. Drainage systems design is approached from the viewpoints of hydraulic capacity, traffic safety, structural integrity, practical maintenance, and architectural aesthetics. System hardware compinents, such as inlets, pipes, and downspouts, are described. Guidance for selecting a design gutter spread and flood fluency are provided. System details and existing computer models are discussed.
