Book excerpt: In recent years, the incorporation of recycled material in the production of plastic pipes has gradually increased. With this new development, the federal government were considering the possibilities of allowing corrugated high-density polyethylene (HDPE) pipes manufactured with post-consumer recycled (PCR) materials installed as culverts under major highways, despite the fact that they may contain impurities and their long-term behavior is still not fully understood. This dissertation was part of the NCHRP Report 870 (Pluimer, 2018), which led to a new revision in AASHTO M-294. This new revision allows HDPE pipes to be manufactured with either virgin or recycled materials. This dissertation presents a test program recently completed at Ohio University, in which corrugated HDPE pipes with varied post-consumer recycled (PCR) material contents were subjected to a forced long-term constant vertical deflection of 20%.
