This guidebook is designed to assist agencies in understanding drainage problems and provide options to consider for mitigating structural damage to pavements due to moisture. Using a navigable PDF format, it helps agencies identify the most appropriate design for their unique situation based on the roadway, understanding of different installation techniques, and knowledge from other agencies’ experiences.

Section topics include Understanding the Need for Better Drainage, Design, Construction, Maintenance Needs, Frequently Asked Questions, Other Considerations, Typical Sections & Specifications, and Resources.
