Rehabilitation and repair methods for culvert structures
Published in Joan-Ramon Casas, Dan M. Frangopol, Jose Turmo, Bridge Safety, Maintenance, Management, Life-Cycle, Resilience and Sustainability, 2022
Eight different general rehabilitation methods were included in the questionnaire. It was found that sandblasting and recoating/painting is not a common method to remove corrosion or coating damage and then improve the wall coating. Cured-in-place pipe (CIPP) is a relatively common method involving installation by feeding a thermosetting resin-soaked sleeve through the host pipe and then expanding and heating to cure the resin. Figure 4 shows that eight state DOTs (21% of the respondents) frequently use it, and 14 out of 38 state DOTs (37%) sometimes use the CIPP method. On the other end of the spectrum, nine state DOTs (24%) never used it.

Cured-In-Place Pipe (CIPP) lining is one of the most common trenchless technology used for underground pipeline rehabilitation (Kuliczkowski, 2000). Its growing popularity results from the fact that this technology can be used for non-, semi- and fully structural rehabilitation and for the rehabilitation of pipes conveying any type of fluid (Kuliczkowski et al., 2010). Its advantage over loose fit technologies lies—because of a significant reduction in hydraulic resistance—in potential for increasing the flow capacity of the rehabilitated pipelines (Kuliczkowski & Dańczuk, 2009).

To address the issue of pipe aging and deterioration, various trenchless technologies, in particular, Cured-In-Place-Pipe (CIPP) and polymeric spray liners have attracted the attention of many water utilities to rehabilitate their deteriorated pipelines. The CIPP and polymeric spray liners are made of thermosetting polymers and can generally cure rapidly (Brown, Fam, & Moore, 2008; Ellison et al., 2010). The advantages of rehabilitating deteriorated pipes with CIPP and polymeric spray linings include internal corrosion prevention, improvement of pipeline hydraulics and water quality, semi-structural or structural support, minimum disruptions to community, minimal effort to re-establish service connections and use of traditional maintenance/repair methods for lined pipes (Marcino & Blate, 2015).

Sewer pipelines around the world are in dire need of repair. Traditional excavation and replacement approaches of buried pipe repair due to the additional socio-economic costs are typically much more expensive than the non-disruptive methods known as trenchless a technology that has such costs at their minimal. The most common trenchless technology repair method is called cured-in-place pipe (CIPP), which has been used for more than 45 years. Despite this wide usage there is no standard approach available in the public domain for tracking the performance of CIPP and other trenchless repair materials. This paper focuses on an assessment of the various types of testing that were developed based on a pilot study and used as part of the CIPP retrospective evaluation project. Many techniques were evaluated and visual inspection and certain destructive tests were found to be the most appropriate assessment techniques.

The Cured-In-Place-Pipe method, CIPP, is the most widely used No-Dig technology for sewer pipelines and has been used since 1970s. These technologies are ruled by the ISO 11295 and, specifically, by the family of standards ISO 11296, 11,297, 11,298 in each of which Section 4 is dedicated to the CIPP. Guidelines are also available, and among them it is necessary to mention the US ASTM 1216 and the German DWA-A 143–2.
