Calenberg synthetic and natural rubber products deliver enhanced elasticity in trackbed structures and protect the overall track bed system thanks to their material characteristics.
This reduces maintenance and repair costs for our clients significantly.
 
Sub-ballast mats are available in different designs and rigidities for use with axle loads up to 250 kN and all train speeds.

The wear-resistant protective layer in USM G 1000 mats withstand mechanical impact such as those from ballast or light construction machinery passing over the mat without the granulate layer (isolating layer) being damaged.

Conical stud mats are used to meet project-specific requirements – from ballast protection in the case of a reduced ballast bed thickness through to efficient isolation of structure-borne sound and vibrations in mass-spring systems.

Using elastic rail pads and base plate pads in special rail fastening systems exploits the load-transferring effect of rails. Wheel forces acting on the rail are distributed across several support points, so that stress is greatly reduced on the directly affected rail support point.

TRACKBED AND SUB-BALLAST MATS

Calenberg track bed and sub-ballast mats (max. length 200 m) are made of synthetic and natural rubber and are available in various designs and rigidities for use at all train speeds and with axle loads up to 250 kN. These mats produce an effective reduction in vibration emissions from railway traffic.

The USM models are manufactured using high-grade rubber blends. They have a high mechanical load capacity and are permanently weather-resistant. The mats absorb virtually no water, excel thanks to their high electrical insulation resistance and provide drainage on the mat level.

The USM series is suitable for both ballasted and ballastless track systems.

 

  • Reduction in stress load on the ballast
  • Increased long-term stability for the track position
  • Reduction in the dynamic wheel forces
  • Reduction in the track and vehicle stress load
  • Potential for reduction in ballast height – important on bridges
  • Reduction in track maintenance costs
  • No replacement required thanks to high fatigue strength
  • Expected service life min. 60 years
