Concrete cracking

You face concrete cracking on track?

Vaperail brings its expertise to fix those issues.

To better undertsand concrete cracking, you need to assess numerous parameters:

  • Pre-stress of the sleeper
  • Dowel evolution stress applied to the dowel
  • Application sheet
Various stress applied

Thermal stress

The key components (concrete, plastic, metal) have very different thermal properties which will generate differential behaviors.

Mechanical stress

The tighetning force applied will generate mechanical stress. The mechanical stress is transfered to the concrete which needs to handle it.

Environment stress

– Dust and dirt
– Overrated equipment
– Materail ageing

Tensile stress

Tensile stress generate a dowel ovalization

From laboratory to Field tests, Vaperail gathers all data

Vaperail developped a solution which encompass:

  • A proven design
  • A metallic shell

This design withstand the stress applied to the concrete

Vaperail solution

Generate a gap between the concrete and the dowel skin to withstand stress applied to the concrete.
