发明名称 USE OF RECYCLED PLASTICS FOR PREPARING HIGH PERFORMANCE COMPOSITE RAILROAD TIES
摘要 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.
