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

Departments of Transportation (DOTs) are increasing employment of asset management strategies in response to federal and state initiatives. Those strategies emphasize the need to preserve assets during the intended service life or, in some cases, to increase service life.  Lowcost and effective treatments applied throughout the life of the asset are employed prior to significant asset degradation, which otherwise would likely require a high-cost reactionary treatment. Culvert and storm drainpipes are increasingly identified as an important asset by transportation agencies due to the quantity and 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 of and provide ratings for buried pipes.  Application of the methodologies in this document identifies asset deficiencies and provides input that may assist facility owners in prioritizing their maintenance needs.  As facility owners identify deficient buried pipes, there will be a growing need for effective rehabilitation methods to restore function or 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 (including full and partial rehabilitation) used by state DOTs for culvert and buried storm drain pipes.  Information to be gathered includes (but is not limited to): (1) Impact of culvert material, size, and condition on rehabilitation methodology  (2) Current and emerging rehabilitation methodologies for culvert and buried storm drain pipes: (3) Rehabilitation method selection criteria (e.g., environmental, materials, site geometry, impacts on the travelling public, current culvert condition, hydraulics, life-cycle costs)  (4) Consideration of structural capacity of host pipe  (5) Suitability of rehabilitation methodologies for in-house maintenance installation  (6) Quality assurance and quality control process of the installation (7) Methods to restore the structural and hydraulic capacity of the soil-pipe system (e.g. chemical or cementitious grouting)   (8) Long-term monitoring of installation and expected service life 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.
