Subsurface drainage is known to pavement professionals to be an important factor affecting pavement performance and preservation of public investment. Numerous studies have emphasized the importance of subsurface drainage, yet subsurface drainage is not always considered a critical component when it comes to design, construction, and maintenance of pavement. The objective of this synthesis is to document the current state of practice by departments of transportation (DOTs) for subsurface drainage in pavement design, construction, and maintenance of highways. Information for this study was gathered through a literature review, a survey of state DOTs, and follow-up interviews with selected agencies. Four case examples provide additional information on how those agencies select projects, design system components, and assess performance of subsurface pavement drainage systems for new and reconstructed pavements.
