Resilient sole 1 which is attached to a concrete layer (2) or which is positioned between a concrete layer (2) and ballast (3), and which is formed by a layer (4) of recycled rubber, in the revulcanised state after devulcanisation, and a layer (5) of structured fibres which is arranged so as to be in contact with the rubber layer, the fibres being partially impregnated in the rubber layer and having a free thickness (8) of structured fibres, assembly comprising the sole and method for manufacturing same.

There is disclosed a railway geogrid construction suitable for use with high speed trains to mitigate the increased impact of Rayleigh waves generated at high speed and/or over soft subgrades, the construction comprising: a track bed (e.g. having rails for a train) which defines a track located on a track plane; a mass of particulate material (e.g. aggregate) forming a layer located beneath the track plane; and a geogrid located in and/or below the particulate mass in a plane (geogrid plane) substantially parallel to the track plane where the average distance between the track plane and geogrid plane, measured perpendicular to both is greater than 0.65 metres.

The invention is a system and method for repairing, improving, and stabilizing subgrade and subsoil/natural ground layers of a rail bed generally consisting of softer soils. One embodiment includes a method of installing subsurface inclusions and ballast fills comprising injected slurry mixtures of stabilizing material such as cement grout mixed with in situ soil. Another embodiment includes a system of installed ground inclusions and ballast fills. Another embodiment includes an integrated system of equipment for emplacing the system of inclusions and ballast fills.

The present disclosure relates to water-soluble binder compositions comprising at least one carbohydrate component and at least one nitrogen-containing compound. In addition, methods for manufacturing the disclosed compositions, as well as methods for reducing or eliminating particulate generation and/or exothermic heat production associated with mineable compositions such as coal, are provided.

A system for and method of stabilizing rail track structures using a load transfer apparatus is disclosed. The load transfer apparatus includes a vertical load transfer element with at least one cross-sectional rib and a top load transfer element with at least one longitudinal vertical fin, wherein the top load transfer element is used to transfer applied locomotive and rail car loads to the vertical load transfer element. In one embodiment, the vertical load transfer element comprises a plurality of cross-sectional ribs spaced along a length of the vertical load transfer element. In another embodiment, the top load transfer element comprises a plurality of longitudinal vertical fins spaced along a perimeter of the top load transfer element to enhance stability of the top load transfer element.

A track maintenance machine, constructed to be mobile on a track, for consolidation of a ballast bed underneath a track, includes a machine frame supported on an undercarriage and a consolidating device, connected to the machine frame, which includes at least one consolidating element constructed to be lowered. The consolidating element is constructed as a consolidating plate which, in a working position, is larger in a longitudinal direction of the track than a distance between two sleepers of the track, and the consolidating plate is disposed to be rotatable in order to turn the consolidating plate into a passing position for lowering or raising between two sleepers. A method for consolidation of the ballast bed underneath a track by using a track maintenance machine is also provided.

A system for and method of stabilizing rail track structures using a load transfer apparatus is disclosed. The load transfer apparatus includes a vertical load transfer element and a top load transfer element, wherein the top load transfer element is used to transfer applied locomotive and rail car loads to the vertical load transfer element. In one embodiment, the top load transfer element includes helical flights. In another embodiment, the top load transfer element includes a flared top. In yet another embodiment, the top load transfer element includes a load transfer cap. In a further embodiment, the top load transfer element includes two or more support legs each with a top support attached thereto. The railroad stabilization system can comprise any one type or any combinations of types of the aforementioned load transfer apparatuses.

A track bed for a railroad track, includes track ballast made from particulate matter and a multitude of railroad ties supported on the track ballast, wherein at least one region of the track ballast is stabilized by a bonding agent that bonds together particles of the particulate matter, wherein the bonding agent is based on a hydraulic binder, in particular cement, and the bonding agent leaves free voids between the bonded particles so that the track ballast has a water draining capability in the at least one stabilized region.

A protective coating system for a railway structure having a waterproof membrane and a ballast mat. The waterproof membrane is disposed on the railway structure. The ballast mat further has a ballast protection coating and a sealing layer. The ballast protection coating is a rubber compound and is disposed on the waterproof membrane. The sealing layer is disposed on the ballast protection layer.

An apparatus for discharging multi-component adhesives of at least two fluidic components onto a granular ballast bed of a railway rail train includes of at least two separate carriages, which can be transferred into a vehicle or a trailer by having the vehicle or the trailer equipped on the inside with rails onto which the carriages can be rolled. The wagons can thus be transported by road to the usage site and can be put into operation by placing them from the trailer onto the tracks of the railway track using extendable rails. The apparatus allows the fully automatic spreading of adhesives over long distances to a ballast bed, so that the ballast bed is bonded in so that trains can continue to run normally. The entire apparatus can be loaded, transported and unloaded on site and put into operation by just two persons.
