Study Finds HDPE Pipe With Recycled Resin Maintains Structural Integrity
Researchers at Villanova University recently completed a study of the performance of corrugated, high-density polyethylene (HDPE) pipe containing recycled HDPE resin in commuter rail installations. The study found its performance to be indistinguishable from pipe made from virgin material.
The three-year field and laboratory evaluation is an important step in validating the use of corrugated HDPE pipe manufactured with recycled materials for commuter railroad and highway applications. The study was funded cooperatively by the Southeastern Pennsylvania Transit Authority (SEPTA) and the National Cooperative Highway Research Program (NCHRP) Project 4-39.
Study-author Dr. Michael Pluimer, a pipe industry authority and PhD graduate from Villanova said:
The railroad industry is reliant on drainage infrastructure materials that are sustainable and resilient and offer a long service life relative to the cyclical live loading conditions typical in these applications.
Since pipes manufactured with recycled materials can be more sustainable and cost-effective than those manufactured with 100 percent virgin materials, it was important to compare the performance and durability of the pipes in these applications.
In the study that commenced in October 2013, two 30-inch diameter corrugated HDPE pipes (manufactured by Advanced Drainage Systems, Inc. - ADS).
