Patent
CA 2360148
A method of maintaining proper distance between railroad rails is disclosed. The method utilizes railroad ties manufactured from a composite of polystyrene and polyolefin components, preferably obtained from recycled plastics. The composite exhibits a dual phase morphology wherein the two phases, polystyrene and polyolefin, intertwine and remain continuous throughout the material.
L'invention concerne un procédé permettant de maintenir une distance appropriée entre les rails d'une voie ferrée. Ce procédé consiste notamment à utiliser des traverses fabriquées à partir d'un composite de constituants polystyréniques et polyoléfiniques, de préférence à base de matières plastiques recyclées. Ce composite présente une morphologie à deux phases dans laquelle les deux phases, à savoir la phase polystyrénique et la phase polyoléfinique, sont liées et restent continues dans l'ensemble du matériau.
