| Abstract | As part of a national initiative sponsored by the Federal Highway Administration (FHWA) under the Highways for LIFE (HfL) program, the Montana Department of Transportation (MDT) was awarded a grant to demonstrate the use of trenchless technologies in rehabilitating 10 deteriorated culverts on U.S. 12 over MacDonald Pass in Powell and Lewis and Clark Counties. This report documents the entire work effort, including the use of two innovative techniques to rehabilitate the corrugated steel pipe culverts. These innovative techniques included a cured-in-place pipe (CIPP) lining and a sliplining system using high-density polyethylene pipe (HDPEP) liners. The rehabilitation effort was a great success. By using trenchless technologies, MDT was able to perform the work without closing any lanes or interfering with traffic flow. The benefits of using CIPP and HDPE included the following: Virtually eliminated traffic delays and lane closures, Provided a safer environment for the traveling public and workers by eliminating exposure to traffic and construction activities, Potentially improved quality because work was done in a controlled environment, Eliminated costs associated with traffic control and roadway excavation, Attained user satisfaction. |
