Re-Examination of the 1994 and Subsequent Sewer and Culvert Installations of Various Pipe Types, Sizes and Depths

In 1994 the Michigan Department of Transportation (MDOT) initiated a sewer and culvert condition research conducted at various locations throughout Southeast and Southwest Michigan to review the performance of concrete, plastic and metal pipe that varied in diameter from 12 in. to 24 in. The present research, conducted in 2011, re-evaluated the current condition of pipe included in the 1994 study and expanded the study scope by adding new sewer pipe locations and 36 in. diameter pipe. The inspection in 2011 added laser profiling and micrometer measuring to the traditional Closed Circuit Television (CCTV) and mandrel inspection methods used in 1994. The inspection and video results from 1994 were compared to the inspection and video results from 2011. The research evaluated the test pipe performance and made recommendations about pipe installation methods, use of mandrel testing versus laser profiling and application of laser micrometer measurement of pipe anomalies. The research evaluated several laser profiling and CCTV devices and their operation in sewers and culverts. Recommendations were made for updating the current MDOT laser profiling specification and implementing laser profiling in MDOT’s practice.
