摘要: A railroad crosstie includes an outer casing made of a 50-50 mixture by volume recycled high density polyethylene and crumb rubber from tires. The upper section lower section, which cooperate to define cavity in beam or beams are installed. Each the include aperture below rail supporting areas insert same composite material is installed within support areas. flowable concrete fills defined including cavities beams.
