Abstract
The invention provides novel railroad ties manufactured from novel composite materials that possess excellent physical and performance characteristics matching or exceeding existing concrete RRTs. The RRTs of the invention can be readily produced from widely available, low cost raw materials by a process suitable for large-scale production with improved energy consumption and more desirable carbon footprint and minimal environmental impact.
