Demonstration Installations of Recycled-Plastic Lumber for Bridges, Marine Pilings, and Railroad Ties
Over the last ten years, recycled-plastic lumber (RPL) and related recycled plastic products have been used in various projects that demonstrate their structural capabilities and versatility in different construction applications. Projects of significance include an all-plastic recreational pier, a RPL bridge designed to carry light vehicles, and large staging platforms at a ski run. RPL materials are not limited to common dimensional lumber sizes but can be fabricated as marine pilings and railroad crossties. Use of RPL and related products in demonstration constructions is helping to develop a performance history for these materials. This process will, in turn, help further the general acceptance and use of these materials by the construction industry.
