Synthesis of Information Related to Highway Practices. Topic 52-12. Rehabilitation of Culverts and Buried Storm Drain Pipes

Departments of transportation (DOTs) are increasing employing asset management strategies in response to federal and state initiatives. Those strategies emphasize the need to preserve assets during their intended service life or, in some cases, to increase their service life. Low-cost and effective treatments applied throughout the asset life are employed prior to significant asset degradation, which would otherwise likely require a high-cost reactionary treatment. Culvert and storm drain pipes are increasingly being identified as an important asset by transportation agencies due to the quantity and the aging of these assets. Recent research completed as part of NCHRP 14-26 - Culvert and Storm Drain System Inspection Manual developed a comprehensive methodology to assess the condition and provide ratings for buried pipes. Application of methodologies in this document identifies asset deficiencies and may provide input to assist facility owners in prioritizing their maintenance needs. As facility owners identify deficient buried pipes, there will be an overwhelming need for effective rehabilitation methods to restore function or to extend the service life of these assets. While some assets will require complete replacement, many facilities will be good candidates for rehabilitation, using both short-term and long-term rehabilitation or repair methods. The objective of this synthesis is to collect and summarize rehabilitation practices used by state DOTs for culvert and buried storm drain pipes. Information gathered includes (but is not limited to): (1) Current and emerging rehabilitation methodologies for culvert and buried storm drain pipes; and (2) Methods to restore the structural load carrying capacity of the facility, including both the structure and the surrounding soil. 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.
