    Abstract: A thermoset composite material and composite railroad crosstie fabricated from the thermoset composite material that comprises a substantially homogeneous blend of an amount of vulcanized rubber particles, polyurea binding agent and urea melamine. The thermoset composite material may also contain a granulated silica material. The thermoset composite material may comprise about 30% to about 50% by weight of the vulcanized rubber particles, and it is subjected to compression molding at a predetermined temperature and pressure for a resident time period forming the composite railroad crosstie. The thermoset composite material and railroad crosstie may further comprise a fibrous glass material in the form of unbundled fibers and/or one more glass mats encapsulated within the thermoset composite material. In addition or alternatively, an elongated core insert may be encapsulated in the thermoset composite material.

    Abstract: Particular embodiments of the invention include a closed-loop tread strip forming unit (100) and methods for forming tread strips using a closed-loop unit. Embodiments of such forming units include a tread strip extruder (110) located at a pre-cure end of the closed-loop tread strip forming unit. Such units include an uncured tread strip handling assembly (120) configured to transport the first uncured tread strip from the first tread strip extruder and to a first tread strip mold member (130). The unit further includes a curing press (150) having an inlet and an outlet, a pre-cure mold handling assembly (140) configured to insert the loaded tread strip mold member into the curing press, a post-cure mold handling assembly (160) configured to receive the loaded tread strip mold member from the outlet of the curing press, a return assembly (170) configured to transfer the first tread strip mold member to the pre-cure end to complete a closed-loop.
