| Abstract | As part of a national initiative sponsored by the Federal Highway Administration under the Highways for LIFE (HfL) program, the Vermont Agency of Transportation (VTrans) was awarded a grant to demonstrate the use of trenchless technology in rehabilitating two structurally deficient culverts located along Interstate 89 in South Burlington and Colchester, VT. The scope of work included adding a new 60-inch diameter culvert alongside the existing culvert at each location using trenchless technology under 40 feet of fill. This report documents the entire work effort, including the use of the innovative trenchless technique of pipe ramming. The addition of a culvert will improve hydraulic capacity and make future maintenance safer and easier. The project included development of a geotechnical baseline report to minimize unexpected geotechnical conditions. After some early construction challenges, the project team successfully implemented the pipe ramming trenchless technology. The lessons learned on this project will be useful when addressing other projects of this type. VTrans was able to perform the work without closing any lanes or interfering with traffic flow. The benefits of using trenchless technology included the following: • Eliminated traffic delays and lane closures • Provided a safer environment for the traveling public and workers by eliminating exposure to traffic and construction activities inherent in conventional open-cut construction • Eliminated costs associated with traffic control and roadway excavation • Completed work for about $1.2 million versus an estimated cost of $4 million for open-cut construction • Completed the project in one construction season versus two for conventional construction |
