Plastic Pipe for Subsurface Drainage of Transportation Facilities

摘要

This report documents and presents the results of a study of buried plastic pipe for the 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. Several piping systems are appropriate for transportation drainage applications. Perforated corrugated polyethylene (PE) tubing, perforated polyvinyl chloride (PVC), and acrylonitrile butadiene styrene (ABS) pipe are selected for underdrains. PVC pipe and ABS composite pipe are selected for storm drains and small culverts. Advantages and possible limitations are presented. Guide specifications are proposed for corrugated PE tubing and PVC pipe. A proposed recommended practice for installing plastic pipe in transportation drainage applications is also presented.
