Cutting and filling of rail joints

In “closed tracks”, where the track area is an integral part of the road, the interaction between the railway and road surface must be coordinated. The ZTV Fug-StB stipulates and regulates the requirements for joint material and joint geometries. In addition to the production (e.g. milling) of the rail joints, OAT also offers filling with various materials. The casting with bituminous rail joint compounds is considered to be the standard. Cooperating with various partners, OAT has developed its own system solution with a cold-processable, environmentally friendly plastic joint compound and improved the bituminous materials.

OPTIONS FOR
THE TRACK.

APPLICATION

In closed tracks (track is an integral part of the road) for the connection between the static track and the elastic (dynamic) rail bearing system.

Ensuring the running freedom of rail vehicle tyres

Filling the gaps in track support plates

CHARACTERISTICS

High daily output through simultaneous production of internal and external joints

Consistent dimensional accuracy thanks to preset milling dimensions

Milling machine is guided through the rails – damage to the rail is ruled out

OAT rail joints – milling technology …

… milled joint flank – the grain is exposed

Inner and outer joint can be made simultaneously
with different depths

ADVANTAGES

Filling the joints with OAT rail Elastic (bitumen):

  • Cost-effective variant of joint filling
  • Improved stretchability even at lower temperatures – higher movement absorption capability compared to standard materials in (head) deflections of the rail

Filling the joints with OAT rail 25 (plastic):

  • Flexible behaviour in the entire temperature range from -30 °C to +80 °C
  • Very good resilience – rail deflections > 0.7 mm absorbable
  • High stability, good consistency even at high temperatures – no sinking of shoe heels or bicycle tyres (risk of accident)
  • Can be used to create various designs through different colours
  • No pressing of asphalt into the joint possible, freedom of movement of railway tyres by maintaining the joint geometries
  • Excellent ageing behaviour with very long service life thanks to the material used
  • OAT’s own system solution with partners
  • Meets the ever-increasing requirements
  • All materials are tested according to TP/TL Fug-StB or DIN 45673-8
