Book Description
Corroded, deteriorated, misaligned, and distorted drainage pipes can cause a serious threat to a roadway. Normal practice is to remove and replace the damaged drainage structure. An alternative method of rehabilitating these structures is to slip line them with a polyethylene liner. Twelve drainage structures were slip lined with polyethylene liners during 1994 in Iowa. Two types of liners installed were "Culvert Renew" and "Snap-Tite". It was found that the liners could be easily installed by most highway, county, and city maintenance departments. The liners restore the flow and increase the service life of the original drainage structure. The liners were found to be cost competitive compared with the removal and replacement of the existing drainage structure. Slip lining has the largest economic benefit when the roadway is paved, the culvert is under a deep fill, or traffic volumes are high. The annular space between the original pipe and the liner was filled with flowable mortar. Care should be taken to properly brace and grout the annular space between the liner and the culvert to avoid deformation of the liner.

Book Description
This synthesis study evaluated culvert rehabilitation (repair) methods involving trenchless technologies that may be appropriate for use in Utah. This report is not intended as a replacement for installation manuals provided by the manufacturers but rather provides a brief description of each method, installation procedures, and highlights the advantages and disadvantages of each. Segmental lining is cost effective in Utah and the most common method of culvert rehabilitation in most western state highway culverts. Cured-in-place pipe and fold-and-form methods are also common but the costs are higher than segmental lining. DOT maintenance personnel can often carry out segmental lining, while contractors with specialized skills and equipment are required for all other methods. This report also presents a survey of culvert relining project costs (western states) and a discussion on burial depth limitations and end treatments. The information provided was obtained through a literature review, surveys of various western State DOTs and interaction with the Utah Department of Transportation (UDOT).

Book Description
"The synthesis describes the current state of the practice regarding state transportation agency standards and strategies that determine and define the service life of drainage pipe. Information for the synthesis was collected by surveying state transportation agencies and by conducting a literature search."--Avant-propos.

Book Description
Published by the Plastics Pipe Institute (PPI), the Handbook describes how polyethylene piping systems continue to provide utilities with a cost-effective solution to rehabilitate the underground infrastructure. The book will assist in designing and installing PE piping systems that can protect utilities and other end users from corrosion, earthquake damage and water loss due to leaky and corroded pipes and joints.

Book Description
PUBLIC ABSTRACT: Slip lining culverts represent a low-cost technique that can restore life to decaying culverts. However, slip liners are smoother than typical host culverts; therefore, they generate higher flow velocities and lower flow depths within the culvert, which are fish passage barriers. One way to mitigate these barriers is by installing baffles. Unfortunately baffles can jeopardize the flow capacity of the culvert. The Utah Water Research Laboratory (UWRL) at Utah State University contracted with the Utah Department of Transportation for $85,000 to test the effectiveness of baffles in improving fish passage through culverts. The goal of this project was to identify swimming limitations for fish passage with regard to slope, flow, and velocity in both a baffled and a smooth-walled high-density polyethylene, HDPE, slip liner. The limitations found from the tests were then used to establish slip-lining guidelines for fish passage culvert rehabilitation. Testing involved evaluating the swimming capabilities of wild brown trout in a 60-ft long, 2-ft diameter, smooth-walled and baffled slip liner. In summary, the baffled culvert supported fish passage up to a 3.5% slope whereas the smooth-walled liner only allowed passage up to a 1% slope. Although baffled culverts improved fish passage, they also decreased the pipe capacity by 74% compared to the smooth-walled liner. This study suggests that baffled slip lined culverts can aid fish passage and are useful for culvert rehabilitation as long as the culvert can still maintain appropriate flow capacity. Applying this knowledge properly to culvert repairs (limited to a 2-ft diameter slip liner) allows for a more economical solution for fish sensitive areas.

Book Description
Research in the area of culvert hydraulics has centered on concrete box culverts and circular corrugated metal pipe culverts. The hydraulic analyses of these culvert types have been well defined for conventional installations, but not for environmentally sensitive and nontraditional culverts. It is desirable to design and construct some culvert crossings to minimize their impact on the natural environment. Culverts are now being designed to maintain natural velocities and minimize turbulence to allow migratory species to pass through the culvert barrel. Such designs may add baffles on the invert, bury the culvert invert, or use bottomless culverts to provide for a natural stream invert. Other designs use larger and wider culverts to reduce the amount of contraction and acceleration.
