Creep Behavior of Recycled Plastic Lumber in Slope Stabilization Applications
Publication: Journal of Materials in Civil Engineering
Volume 19, Issue 2
Abstract
Slender recycled plastic pins (RPPs) can be used to stabilize earthen slopes by driving the RPPs into the face of the slope to intercept the sliding surface and “pin” the slope. The RPPs will be subjected to lateral (bending) forces, and their ability to resist deformation will strongly influence the success of the RPPs for stabilizing slopes. Arrhenius modeling was used to predict the time for the RPPs to reach creep failure. Engineering properties and strain rate effect of four different types of RPPs were evaluated and are reported in this paper. Arrhenius modeling showed creep failure ranged from at field temperature and stress levels. Compressive strengths ranged from and compressive moduli from at 1% strain, while flexural strengths ranged from and flexural moduli from at 1% strain.

The encouragement and support of Mr. Thomas Fennessey, technical liaison for this project, Missouri Department of Transportation, is always appreciated. This program would not have been possible without the kind cooperation of Bedford Technology, LLC (Ms. Rachel Aanenson), Epoch Composite Products (Mr. Randy Jolitz), and Resco Plastics (Ms. Sabine Zink). These manufacturers provided their products for testing and evaluation. This report is based on work supported by the Federal Highway Administration under Cooperative Agreement No. DTFH61-98-X-00095 through the Recycled Materials Resource Center at the University of New Hampshire, Durham, New Hampshire. The first writer was partially supported by the Civil and Environmental Engineering Department, University of Missouri–Columbia.
