The U.S. Army Engineer Research and Development Center, Construction Engineering Research Laboratory (CERL) led a team that developed, demonstrated, and patented innovative recycled plastic composite material for use as railroad crossties to replace chemically-treated wood ties. Replacement of turnout ties is a major cost item because of the size and complexity of these components. Since the mid-1990s CERL has conducted research on composite RR ties made of recycled post-consumer waste plastics. Because these plastic composite ties are inherently resistant to moisture damage, rot, and insect attack, they require no chemical treatments as do wood ties.
