Performance of Corrugated Pipe Manufactured with Recycled Polyethylene Content

TRB’s National Cooperative Highway Research Program (NCHRP) Report 696: Performance of Corrugated Pipe Manufactured with Recycled Polyethylene Content provides potential specifications for corrugated drainage pipe manufactured with recycled high-density polyethylene (HDPE). The report includes proposed draft specifications for recycled HDPE, formulations of virgin and recycled HDPE, and drainage pipe containing recycled HDPE.

The following three appendixes of NCHRP 696 are available in electronic format only.
• Appendix B: Recycled Polyethylene Resins
• Appendix C: Recycled-Resin Blends
• Appendix D: Pipe Containing Recycled HDPE
