Synthesis of Information Related to Highway Practices. Topic 55-17. Practices to Enhance Resiliency of Existing Roadway and Embankment Culverts

State departments of transportation (DOTs) recognize that management and maintenance practices for existing roadway and embankment culverts fundamentally influence culvert performance and have subsequent impacts on adjacent assets and overall transportation system performance. State DOTs actively research and implement methods to reduce costs, identify and reduce risk, minimize maintenance, improve performance, and ultimately increase the longevity of culverts. The needs of state DOTs to reduce culvert degradation impacts and improve resilience are common, yet the approaches may be diverse. Variability in climate, climate events, seismic susceptibility, slope and embankment stability, watershed characteristics, and urban development and land uses create system challenges. Although the demands that state DOTs face vary significantly, commonalities exist, and practices used to enhance the resiliency of culverts can be broadly employed. This synthesis will provide awareness of management and maintenance practices used by other state DOTs to address and improve the performance and resiliency of their existing culverts. Culverts were frequently identified and assessed as vulnerable components to extreme events and climate change during a 2013-2015 pilot study (FHWA-HEP-16-079). Documenting practices and remedial measures for culvert management and maintenance is an important step in planning for improved system operations, performance, and resilience. The objective of this synthesis is to document management and maintenance practices used by state DOTs to enhance resiliency of existing roadway and embankment culverts.
