Rubber-reinforced concrete (reinforced concrete) heavy-duty decking, project A1.RBU.000 (A1.BTU.000) (hereinafter referred to as “the decking”), is designed for installation at railway crossings in straight and curved track sections where heavy vehicles and/or tracked machinery pass, to ensure safe, convenient and rapid crossing of railway tracks by vehicles at the same level as the top of the rail head.
The decking consists of high-strength rubber-reinforced concrete slabs manufactured using fibre-reinforced concrete and heavy concrete of class not lower than B50, and elastic rubber sealing profiles that provide rigidity to the overall structure:
-
internal seals secure the slabs between the rails within the track gauge;
-
external seals ensure tight adhesion of the outer slabs to the rails.
The decking is used on public and non-public railway tracks, metro tracks and tram tracks for the passage of vehicles with an axle load of up to 45 t/axle. The decking design for tracked machinery passage allows the replacement of worn rubber elements.
At the customer’s request, the slabs can be manufactured without a rubber coating, which allows increasing the axle load from passing vehicles.
The decking is installed on railway tracks with the following rail fastenings:
-
KB-65 on type Sh-1 reinforced concrete sleepers;
-
ARS-4 on type Sh-ARS reinforced concrete sleepers;
-
ZhBR-65 on type Sh3/Sh3-D reinforced concrete sleepers;
-
KD-65, DO-65, DO-50 on wooden sleepers.
The decking structure is modular and allows covering a railway crossing of the required width (slab multiples of 1300 mm, 1605 mm, 1950 mm, 2140 mm, 3020 mm, 3250 mm).
The modular structure provides the ability to:
-
cover a crossing of the required width, with the required width assembled using the appropriate number of slabs;
-
install on straight or curved sections of track (slab width is selected taking into account the radius of the section and operating conditions);
-
perform rapid installation (dismantling) of the decking during repair works and technical maintenance of the railway track;
-
extend the service life of the road surface at the junction with the decking;
-
reuse the decking slabs multiple times, including for temporary road crossings over railway tracks during construction works.
When installing the deckings, it is recommended to use support blocks and clamping beams to strengthen the decking structure and distribute the perceived load at the junction with the road surface.
