This report documents and presents the results of a study of buried plastic pipe for the drainage of transportation facilities. The overall objective of the study was to develop practical guidelines for the selection, design, specification, and installation of plastic pipe for subsurface drainage of transportation facilities. Design, installation, and performance criteria were developed, analyzed, and evaluated in order to select pipe systems suitable for the application. Ongoing state installations of plastic pipe were monitored to observe installation practice. Full-scale field tests were performed in cooperation with states to obtain realistic data on the effects of installation conditions and on pipe behavior and performance. This information is summarized herein. The documentation developed from this work presents and evaluates criteria for selection of plastic structural materials, design procedures, and installation guidelines. Guide specifications are proposed for corrugated polyethylene (PE) tubing and polyvinylchloride (PVC) pipe. A proposed recommended practice for installation of plastic pipe in transportation drainage applications is also presented. (Author).
