Composite railway tie and method of manufacture thereof

摘要: A composite railway tie, and process for manufacture thereof, is disclosed. The tie comprises a main body portion being made of first material comprising binding constituent in proportion about 10% to 20% by volume, an aggregate 80% 90% volume. plastic chosen from the group polyethylene blend having at least polyethylene. form irregular multi-faceted pieces consisting crushed furnace slag, gravel, limestone, granite, basalt, trap rock, mixtures thereof. are distributed otherwise arranged within second so that opposed surfaces have partial contact, one with another, contiguous manner. In essence, (preferably polyethylene) holds together this interlocked fashion, as provide strong tie. An inner strengthening core, high tensile strength, may also be included
