摘要： The invention relates to a sleeper for the track superstructure, which is manufactured in one piece from a plastic material, with the sleeper having an elongated base shape with two end sections, which are connected by a middle section of the sleeper and held at a distance and on their upper side in each case one contact surface is provided for in each case one rail to be supported on the respective end section with a reinforcement extending in the longitudinal direction of the sleeper being embedded into the middle section. In order to design such a plastic sleeper such that it has optimised strength and can be reliably manufactured even using cost-effective plastic/sand mixtures having a high proportion of sand, the invention proposes that the reinforcement extends over the length of the middle section, that the reinforcement is in each case anchored in the respective end section an edge region of the end sections assigned to the middle section and in that the reinforcement is wholly or partially arranged in the upper quarter of the height of the sleeper.

摘要： 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.

摘要： A railroad crosstie comprising a laminated plurality of strips of a flexible polymeric material, preferably plies cut from rubber tire casings. The plies are glued together, preferably under pressure, to form a tie-shaped entity having any desired dimensions, for example, 9 inches wide by 7 inches high by 8.5 feet long. A T-shaped metal reinforcing spine is contained longitudinally within the laminated strips, the spine having both horizontally- and vertically-oriented load-bearing elements. Preferably, the laminated plies and the metal spine are bound together by a plurality of bailing straps. The crosstie further comprises a weather-resistant covering that preferably includes a heat-dispersing element such as ground glass or ceramic.

摘要： Thermoplastic polymers, rubbery polymeric components and reinforcing fillers are mixed and heated to a range of 380° F. to 440° F. The resulting mixture is then fed into a Banbury mixer, with the resulting mixture fed into a diverter feeding two molds. The velocity of the piston of each mold being filled is controlled to thereby control the density of the molded product along its length. As each mold is filled, it is deposited in a cool water bath (50° F.-60° F.) while the next mold is being filled. The molds are sequentially transferred to an air cooling rack to complete the process. A texture, generally comprising indentations perpendicular to the longitudinal axis on the molded object, provides a frictional surface between the railway crosstie and the ballast beneath the crosstie.

摘要： A variable thickness fabric mat for use with railroad track right of way beneath the track structure. The mat has a central portion of predetermined thickness, and lateral shoulder portions of a reduced thickness as compared to said cental portion, with the central portion being of a predetermined width of adequate dimension to generally completely underlie the railroad track structure. The mat provides a method for transmission of force from a train on the railroad track structure to be spread over a greater area of the underlying earth bearing surface, and with the mat possessing the capability of passing water, and aiding in draining water from the soil beneath the mat, as well as from the top and sides of the track support.

摘要： A reinforced railroad crosstie formed by molding and bonding comminuted lignocellulosic material into a monolithic beam around a plurality of wooden reinforcing members which have relatively clear and straight grain, a high modulus of rupture and a high modulus of elasticity and are able to withstand a high amount of compression without crushing. The reinforcing members are positioned within the crosstie proximate lines of maximum tensile stresses expected to be induced in the tie by different bending influences caused by passing trains and varying conditions of the underlying ballast. The members are also positioned within the crosstie so as to avoid interference with the spikes employed to fasten the rail to the tie.
