Synthesis of Information Related to Highway Practices. Topic 52-10. Subsurface Drainage Practices in Pavement Design, Construction, and Maintenance

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 will be collected through literature review, a survey of DOTs, and follow-up interviews with selected agencies for the development of case examples. Information gaps and suggestions for research to address those gaps will be identified.
