Drainage of Highway Pavements

Vincent D. Reynolds, MBA, PE

Effective highway drainage is essential to the proper function of traffic along the highway. Water on the pavement can cause several problems such as hydroplaning, and visibility from splash and spray. Water on the roadway could also inhibit the proper flow of traffic thereby increasing congestion

This course will discuss the hydrology and hydraulics of highway pavement drainage. The methods for determining flow including how to determine the time of concentration will be discussed. Included in the hydraulic discussion will be the design aids for determining gutter spread and grate selection.

This course is material is based on the document “Drainage of Highway Pavements,” published on the website of the Federal Highway Administration.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
