NCHRP Synthesis 20-05/Topic 52-10 [New]

Designing and Accommodating Drainage in Pavement Design, Construction, and Maintenance
[ NCHRP 20-05 (Synthesis of Information Related to Highway Practices) ]

  Project Data
Funds: $45,000
Authorization to Begin Work: 5/1/2020 -- estimated
Staff Responsibility: Melissa Welch-Ross
Fiscal Year: 2021

Preliminary Scope

Drainage is known to pavement professionals to be an important factor affecting pavement performance and preserving public investment. Numerous studies have been conducted to date that emphasize the importance of drainage. Yet despite this awareness, drainage is not always considered to be a critical component when it comes to design, construction, and maintenance of highway projects.

The objective of this synthesis is to document the current state of the practice by departments of transportation (DOTs) for designing and accommodating drainage in pavement design, construction, and maintenance.

Information gathered includes (but is not limited to):
• Methodologies for assessing drainage needs during the design phase
• Parameters used and documentation methods for drainage assessment during the design phase
• Mechanisms to quantify the benefits of drainage features and methods to document the effectiveness
• Drainage features used
• Methodologies for quantifying the structural capacities of pavement structures designed with sub-surface drainage systems.

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.
