Piehl, Rob . 2005. Summary of Trenchless Technology for Use With USDA Forest Service Culverts. 0577 1201P. San Dimas, CA: U.S. Department of Agriculture, Forest Service, San Dimas Technology and Development Center. 28 p.
This report, which summarizes the trenchless technologies most appropriate for U.S. Department of Agriculture (USDA) Forest Service roadway culvert applications, can help USDA Forest Service engineers best determine where and when to use this rapidly evolving technology. Techniques for replacing or rehabilitating corrugated metal pipe (CMP) culverts, 18 inches or greater in diameter, are emphasized because they are commonly used for USDA Forest Service culverts. The discussion of trenchless technology that benefits other, smaller nonculvert pipes, such as small utility lines, is incidental to this report.
