Road and railway construction

Út és vasútépítés 1

At road, railway and dam construction draining of the surface water below the structure, layer separation and filtration has to be handled by installing woven and non woven geotextiles. In case the subgrade’s load capacity does not reach a predefined value, the subgrade can be stabilized using geogrids and woven geotextiles and furthermore the structural thickness can also be reduced

Recommended geosynthetics as solution to problem concerning the application field:

Load capacity of the subgrade almost sufficient, layer separation and surface water drainage is recommended; to reduce cost during construction and increase the lifetime of the road

Recommended geosynthetic Function of the geosynthetic
Separation Filtration
  • Separation of structural layers
  • Prevents intermixing of layers
  • Filtration

Load capacity of the subgrade is not sufficient , subgrade stabilization is necessary; the layer thickness of the structure can be significantly reduced, while the lifetime of the road structure is increased

Recommended geosynthetic Function of the geosynthetic
  • Bontec LW woven geotextile
  • Bontec HW woven geotextile
  • Enkagrid TRC geogrid composite
Separation Filtration Reinforcement
  • Separation of structural layers
  • Prevents intermixing of layers
  • Filtration
  • Subgrade reinforcement
  • Reduced structural layer thickness
  • Enkagrid MAX biaxial geogrid
  • Enkagrid PRO uniaxial geogrid
Reinforcement
  • Subgrade reinforcement
  • Reduced structural layer thickness

Pavement rut formation on the wearing layer, prevent formations of cracks, increase lifetime of the wearing layer

Recommended geosynthetic Function of the geosynthetic
  • PAVEMAT tension relieving layer
Separation
  • Separation of structural layers
  • Delays formation of pavement ruts
  • Prevents water reaching the cracks of the lower layers
  • Tension distribution layer, prevents spreading of the cracks
