Highway Subdrainage Design

Vincent D. Reynolds, MBA, PE

Excessive and uncontrolled subsurface water can be detrimental to the structural stability of roadway pavement. Subsurface water can be a result of water infiltrating from the pavement surface or from groundwater. The removal of water from the pavement section and subgrade can be done with the use of subsurface drainage structures that collects the water and drains it away from the pavement cross section.

This course will provide methods for draining subsurface water away from the pavement section. The control of infiltration and maintenance aspects of subdrainage systems will also be discussed.

This course is based on the document “Highway Subdrainage Design,” 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.
