Abstract

A thermoset composite material that my used in the fabrication of structural components including railroad ties comprise a substantially homogeneous blend of an amount of vulcanized rubber particles including a predetermined ratio of different particles sizes, and a thermoset elastomeric binding agent added to the vulcanized rubber particles. The blend may comprise about 30% to about 97% by weight of the vulcanized rubber particles, and the blend is subjected to compression molding at a predetermined temperature and pressure for a resident time period forming the composite material. The ratio of different rubber particle sizes is selected so that the composite material has a desired density or is within a range of desired densities.
