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.
